List of The Hardy Boys characters

Many characters have appeared in the fictional series of books about The Hardy Boys.

Character history

Original series

At the beginning of the original Hardy Boys series, Frank is only 16 years old (as opposed to 18 after the revisions between 1959 and 1974) and both he and Joe want to follow in their famous father Fenton Hardy's footsteps as detectives. When the father of one of their school friends is wrongly accused of stealing, the Hardy boys take it upon themselves to clear his name and solve the mystery.

After Frank and Joe solve their first case, Fenton—although he had not wanted his sons to get into the detective business because of the dangers involved—starts asking for their help on some of his cases.

Fenton and his boys working together play a bigger part in this series than in any of the following Hardy Boys series.

In this series, Frank is in the same grade as Joe (who is a year younger), because he lost a year due to sickness, but in all the other series he is a grade ahead of Joe and him losing a year is never mentioned.

Casefiles

In the Casefiles, the differences between Frank and Joe are more pronounced as Joe's personality is somewhat changed because of the death of his girlfriend, Iola Morton. Frank (although the death of Iola does affect him somewhat) stays more or less the same.

In the Casefiles series, the Hardy boys collaborate with The Gray Man, who works for the Network—a secret government intelligence agency—to fight the Assassins, an international terrorist organization responsible for his girlfriend Iola's death.

Also, the Casefiles were written between the late 1980s and 1990s unlike the original series (1927–79), home computers were available, and because of this Frank's character is modernized and he becomes a PC computer buff; in one book he is even able to hack into the Bayport City computer system. Frank is also well-versed in the making of bombs and is also able to disassemble them, which saves his and many other's lives many times. As was the case in the previous series, Joe acts as the mechanic for the boys and is often described as being very athletic.

Super Mysteries

This was a series of 36 paperback novels in which the Hardy Boys teamed up with intelligent young female sleuth Nancy Drew.

One character arc seen throughout the series is the mutual attraction between Nancy and Frank. The couple shared a kiss twice in the series; the first in book 5, The Last Resort, when the two are trapped after an avalanche and fear that they will die. The second is in Secrets of the Nile, where they kiss on a balcony after the case is solved. However, the kiss is interrupted by Bess Marvin. Another hint at their relationship is when Nancy's longtime love interest Ned Nickerson saves her. However, a disheveled Nancy calls out Frank's name instead, believing him to be her saviour, and severely disheartening Ned.

The two decide not to pursue relationships, believing that they belong with their current partners, Ned Nickerson, and Callie Shaw. Both partners are jealous of the time and bond shared by the detectives, especially shown in Ned Nickerson. He greatly disapproves of Nancy's sleuthing in the series, as well as the time she spends solving them with the Hardys.

Another romance is hinted at between Joe Hardy and Bess Marvin, although there is much less evidence of this attraction. Neither relationship was ever given a final closure.

Undercover Brothers

In this series, Frank and Joe are both undercover agents for American Teens Against Crime (ATAC), an organization founded by Fenton Hardy.

This is the first series in which Frank and Joe are regularly single (not dating Callie Shaw and Iola Morton, as they did in the previous series), and have different love interests from book to book. Frank becomes nervous around teenage girls, even though they are attracted to him more in this series than any other. In contrast, Joe, in a similar manner to his personality in the Casefiles series, is a huge flirt; however, unlike in Casefiles, girls are relatively less interested in him, preferring Frank, which greatly annoys and frustrates Joe. The brothers use a more modernized speech style, and frequently tease and get on each other's nerves; nonetheless, they are still very close and protective of each other as in all of the previous series.

Vehicles owned by Frank and Joe

Frank and Joe owned a large number of cars or automobiles. In the originals, they have motorcycles, but Joe totals his in The Shore Road Mystery and they purchase a yellow convertible soon afterwards. The car appears in the series, for over fifty books, before it is blown up in #74 Tic-Tac-Terror. Frank and Joe receive a newer model of their yellow convertible from a jewelry firm because they successfully recovered an emerald valued at $1 million dollars in the same book. The Hardys use this new yellow convertible between #75 Trapped At Sea and #84 Revenge of the Desert Phantom, at which point Chief Collig gives the Hardys a black surplus police van, which the Hardys use until Mystery Stories #190 Motocross Madness. It is unknown what the Hardys did with their second yellow convertible after Collig gives them the van.

In the Casefiles, the Hardys' second yellow convertible is blown up by the Assassins (which also kills Iola Morton). After Frank and Joe save the Bayport Mall from being destroyed by the Assassins, they are given a black van by the Bayport Mall Association. In Casefiles #100 True Thriller the van is also blown up. They finally purchase a blue van which remains with them until the end of the series. In the Undercover Brothers series, Frank and Joe own custom sport bikes, decked out with the latest in accessories. They also own a speedboat named the Sleuth, which is equipped with a Ham Radio transmitter, as is described in The Secret Warning. The boys also own and store, in the same boathouse as their boat, an iceboat. The iceboat only makes one appearance in The Mystery of Cabin Island.

Sports played by Frank and Joe

Frank plays many school sports along with his brother. Frank is the captain and quarterback of the Bayport High football team, but by the time of the later Digests, he gives up his place on the team so he can concentrate on his studies. He also does endurance running for the Bayport High track team and is on the swim team. He also plays baseball, basketball, and soccer. Frank is also interested in martial arts, the game of chess and, in The Clue of the Broken Blade, fencing.

Frank Hardy

In-universe information
Gender	Male
Occupation	A.T.A.C agent, affiliated with The Network
Relatives	Father: Fenton Hardy Mother: Laura Hardy Brother: Joe Hardy Aunt: Gertrude Hardy
Home	Bayport

Frank Hardy is the older (18) of the two Hardy brothers in The Hardy Boys novel series by Franklin W. Dixon. In the Hardy Boys (2020 TV Series), Frank is 16 years old, 4 years older than Joe (12).

Frank has dark brown hair and dark eyes, inherited his parents' good looks, and, like Joe, has a muscular frame. He lives in the town of Bayport, NY with his parents, Fenton and Laura; his younger brother, Joe; and his aunt, Gertrude.

Joe is not only Frank's younger brother but his best friend and crime-fighting partner. Working together, the two have solved countless mysteries. Around Bayport, Frank and Joe have quite a reputation as amateur detectives. The Hardy boys are often helped by their friends, most notably best buddy Chet Morton.

Compared to his brother Joe, Frank is the more logical, rational one. While Joe wants to jump straight into a situation, Frank is the one to hold him back and think through all the logical possibilities. More than once, Frank has surprised the villains by having the entire case figured out. Frank is also usually the one that must look for Joe when he gets lost or kidnapped.

In the Casefiles series, Joe jokingly refers to Frank as the brains of their operation and himself as the brawn. The Hardy boys make an excellent team because their abilities mesh perfectly.

Frank and Joe both attend Bayport High, along with their friends Biff Hooper, Tony Prito, Phil Cohen, Iola Morton (excluding the Casefiles) and the aforementioned Chet and Callie.

Frank is said to be a bomb buff (see Countdown to Terror in which he defuses two bombs) and has disarmed an atomic bomb saving the town of Halifax.

Frank is very protective of Joe, as every time someone threatens or hurts his younger brother, Frank goes into a cold-blooded rage.

Frank and Callie have a mild romance in the casefiles series, obviously has a crush on Nancy, and in the Hardy Boys adventures series, seems to hug and hold Joe's hand multiple times.

Fenton Hardy is a private investigator in the popular Hardy Boys novels.

Father of Frank and Joe, Mr. Hardy is married to Laura Hardy, and brother to Aunt Gertrude. After retiring as a NYPD Detective Lieutenant from the city's 71st Precinct, Hardy became a famous private investigator. He lives with his family in Bayport. He is also the co-founder of a top-secret organization, ATAC, American Teens Against Crime, the agency for which his sons, Frank and Joe, work.

An excellent shot with a pistol, one Bayport criminal alleges Fenton Hardy never misses.

Laura Hardy

Laura Hardy is the pretty and petite stay-at-home (in the Undercover Brothers, as a librarian) mother of Frank and Joe. She is married to Fenton Hardy the private investigator and they all live in fictitious Bayport with Fenton's sister, Aunt Gertrude.

Aunt Gertrude

Occupation	Homemaker
Relatives	Brother: Fenton Hardy Sister-in-law: Laura Hardy Nephews: Frank Hardy, Joe Hardy
Home	Bayport

Gertrude "Trudy" Hardy is the unmarried aunt of Frank and Joe Hardy (the Hardy Boys of the title) and the sister of their father, Fenton.

She is known to have a peppery temper and on more than one occasion to go "on the warpath". She owns an old Volkswagen Beetle. In the Undercover Brothers series she goes by Trudy, and sometimes Frank and Joe call her Aunt T.

In some installments of the original series, Gertrude appears to be a full-time resident of the Hardy household. In others, she is often present for a visit, sometimes brief and sometimes extended. Her maternal care for the boys doesn't seem to put her in any conflict with the brothers' actual mother Laura, but her characteristics — genial overbearingness, comic frettiness, moral disapproval — make her a much more developed character. In the TV series The Hardy Boys/Nancy Drew mysteries, the mother has been completely written out and Aunt Gertrude has become Frank and Joe's only maternal figure.

Gertrude frequently expresses her maternal care for the boys and their friends through her cooking, and it is generally agreed (particularly by the occasionally gluttonous Chet Morton) that she excels in this area.

Chet Morton

Chester "Chet" Morton appears in most of The Hardy Boys books. He often tags along on the boys' little adventures. He is portrayed as a stout fellow and is often described as "plump" or "chubby", with a love for food. The books describe his bright yellow jalopy, which he had named "Queen", as the "pride of Chet's life", and he works on it daily to "soup up" the engine. His stature and not-athletic nature make him a frequent source of comic relief; however, it is noted that he can move fast when needed. His whimsical nature is frequently a distraction for him, though it occasionally leads to an unexpected break in the case. Throughout the original canon, Chet is always diving into new hobbies like botany in The Shore Road Mystery or ballooning in The Clue of the Hissing Serpent.

Iola Morton

Iola Morton is the girlfriend of Joe Hardy throughout the book series.

She has dark hair, green eyes, and a medium frame. Her best friend is Callie Shaw, the girlfriend of Frank Hardy. Iola is the sister of Hardy Boys' close friend Chet Morton. She lives on a farm near Bayport with her parents and her brother. She is usually paired with Joe as he thinks "she was quite the nicest girl in Bayport High".

In The Hardy Boys Casefiles first book, Dead on Target, she is killed by a car bomb meant for Frank and Joe. However, Iola appears in the Original Continuity books which ran during and long after the Casefiles series had ended. In many other Hardy Boys books, she is mentioned alive.

Iola is featured in The Hardy Boys: Undercover Brothers, but she and Joe are not dating. In the graphic novels also released under the Undercover Brothers banner, however, they are.

Iola once again appears in the Hardy Boys Adventures series, but she is again not dating Joe.

Biff Hooper

Allen "Biff" Hooper is a six-foot, blond-haired, muscular friend of the Hardy boys. He excels at boxing, wrestling, football and fencing. He has an ambling gait, "with which he could cover a tremendous amount of territory in a short time".

His nickname comes from a distant relative who was a boxer named Biff. He owns a bloodhound named Sherlock and a Great Dane named Tivoli, and a motorboat named Envoy. He can play the harmonica.

In one of the Casefiles he is part of "The Circle of Twelve", which is a group of vandals. He is in the group because of his girlfriend. His association with the Circle of Twelve nearly gets him killed.

In the Clues Brothers series, he is depicted as a bully rather than a friend to the Hardys. He first appears in secret files #5 Monster Of A Mystery.

In the Hulu 2020 series, Biff is a girl in the adaptation with her nickname being shortened for Elizabeth when she couldn't pronounce her name correctly in kindergarten.

Tony Prito

Gender	Male
Occupation	Prito co., Mr. Pizza Restaurant manager
Relatives	Father: Mr. Prito Mother: Mrs. Prito (nee Simone) Uncle: Matt Simone Aunt: Mrs. Simone (nee Mulvaney) Cousin: Mike Simone
Home	Bayport

Tony Prito appears in the popular The Hardy Boys book series by Franklin W. Dixon.

Son of Italian immigrants and a close friend of Frank and Joe Hardy, Tony works for his father's construction company and in the Casefiles is also the manager of Bayport's local pizza parlor, Mr. Pizza. He is the owner of the motorboat Napoli, which is destroyed in #36 and replaced with the Napoli II, and drives one of the Prito Co. pickup trucks.

He attends Bayport High and is a standout second baseman on the school's baseball team and a talented wide receiver on the football team.

Tony is a handsome 19-year-old with curly black hair, brown eyes, and olive skin. Though not big, he is wiry, with lightning-quick reflexes. In Casefiles #41, Highway Robbery, it is said that he is five inches shorter and twenty pounds lighter than the Hardy Boys, who are 6-1 and 6 feet, so Tony is around 5-7 or 5–8 feet.

Callie Shaw

First appearance	The Hardy Boys #1 The Tower Treasure (1927)
In-universe information
Gender	Female
Occupation	Student
Relatives	Father: Mr. Shaw Mother: Mrs. Shaw Cousin: Pollie Shaw
Home	Bayport

Callie is the girlfriend of the elder Hardy boy, Frank Hardy. She first appeared in 1927 in the first volume of the series, and she appeared or was mentioned in almost all of the following 57 volumes (as well as most of subsequent 'Digest' series), but never had an important role until 1987 and the death of best friend Iola Morton in The Hardy Boys Casefiles #1 Dead on Target. She is a blonde with brown eyes and tends to start giggling like mad for no reason.

Original series

Other than being described as "Frank's favorite date" and "one of the prettiest girls attending Bayport School", the virginal Callie does not have much, if any, of a role in the first 58 books; however, from book 59 (Night Of The Werewolf) till book 190 (Motocross Madness), Callie is made to be more of a modern woman (depending on the decade in which the stories were written) and is not presented to be a "frail" woman as in the stories from the 1920s to the 1970s, but she still retains her personality and characteristics of the earlier books.

In the original books, Callie lives with her older cousin Pollie Shaw, the proprietor of a beauty parlor in Bayport, while her parents live in the country, sending her an allowance to pay for her expenses. By 1959, she lives with her parents, only a few blocks away from the Hardys’ home, where she lives for the remainder of the series and spin-off series.

Casefiles

Callie's role is greatly increased in the Casefiles series. Following the death of Iola in book #1, no longer is she merely Frank's date, but a competitive, brave, young woman, who is always ready to assist the Hardys on their cases, whether they want her to or not. Working on their cases, Callie saves the Hardy brothers, more than once, notably in book #8 See No Evil and #80 Dead of Night. The Hardy Boys spend much of the latter novel mourning her, incorrectly thinking she has been slain. In some of the early Casefiles, she and Frank's younger brother, Joe occasionally seem to be at odds, by the end of the series, however, they get along quite well.

Undercover Brothers

In this Hardy Boys series Callie's role has again been reduced; in the first 20 books of the series she only appeared once and was no longer described as Frank's girlfriend, but just as a ‘‘close friend of the Hardys’’.

TV portraits

In the 1970s TV show, The Hardy Boys/Nancy Drew Mysteries, Callie was played by Lisa Eilbacher. In the show, Callie works part-time for the Hardy boys' dad, Fenton Hardy (Ed Gilbert).

Occupation	High school student
Relatives	Father: Mr. Cohen Mother: Mrs. Cohen
Home	Bayport

Philip Cohen appears in The Hardy Boys book series by Franklin W. Dixon.

A close friend of Frank Hardy, Phil is very artistic and a genius when it comes to electronics; in the series he often helps out the Hardys when they need a video to be digitally restored or a computer system hacked into. (However, due to the time period that the original series was set in, these talents were not discussed; instead, Phil was essentially an "everyman" that would occasionally help out the Hardys.) Phil is also skilled at painting and is a great tennis player. In The Mysterious Caravan, book #54 in the original series, it is said that he holds the county tennis championship. Helping the Hardys, Phil has faced quite a bit of danger throughout the series, but no matter what happens, always has a good sense of humour.

Phil is tall, slender, and agile with wavy brown hair, glasses and dark eyes.

Also notable is that Phil is Jewish and along with fellow Hardy Boys character Tony Prito, was one of the first fictional non-WASP characters to be portrayed as a normal, fully assimilated teenager.

Chief Ezra Collig

Police Chief Ezra Collig (in The Disappearing Floor, his first name is "Clint") is the Chief of the Bayport Police. His acceptance of the Hardys varies from book to book; in some he welcomes their assistance, while in others he resents it, claiming his Department is capable of handling the investigations without amateur help.

Sam Radley

Sam Radley is a friend and fellow private investigator to Fenton Hardy. Sam often works for Fenton as an operative, along with Fenton's sons, Frank and Joe.

Sam is a skilled detective and tireless worker, who sometimes has to camp out at stakeouts for days on end while working for Fenton Hardy.

Ethel Radley

Ethel Radley is the wife of Sam Radley and a good friend of the Hardy family.

Jerry Gilroy

Jerry Gilroy was a close friend of the Hardy Boys. He appeared occasionally in the first 20 books and then again in The Short-Wave Mystery at a party hosted by Chet Morton, but was not involved again after that. Also notable is that in The Great Airport Mystery, he is referred to as Jerry Madden.

Jack Wayne

Jack Wayne is a veteran pilot who often flies assignments for Fenton Hardy and his boys. His plane is named Skyhappy Sal; however, it crashed and burned while the Hardy boys were investigating The Disappearing Floor.

Home	Manhattan

Vanessa Bender is Joe Hardy's girlfriend in most of The Hardy Boys Casefiles book series after the death of his first girlfriend, Iola Morton, in Casefiles #1 Dead on Target.

Frank and Joe Hardy (the Hardy Boys of the title) first met her sometime after Iola's death when she first moved to Bayport from Manhattan, they got to know her better when they were working on a case for her mother in Casefiles #69 Mayhem in Motion. After the case was successfully wrapped up she and Joe started dating and when the Casefiles series was canceled in 1998 with the publication of #127 Dead in the Water, they were still a steady couple.

The Gray Man

Arthur E. Gray
The Hardy Boys character
First appearance	The Hardy Boys Casefiles #1 Dead on Target (1987)
In-universe information
Gender	Male
Occupation	The Network agent

The Gray Man is a high-ranking member of a top-secret crime-fighting organization called the Network. He is Frank and Joe Hardy's contact in the agency.

The Hardys first met him at the funeral of Joe's girlfriend, Iola Morton, who was killed in a terrorist car bomb planted by The Assassins. Following the events of Iola's death, Frank and Joe had vowed to track down her killers, and the Gray Man was a man in the know, having battled Iola's killers previously.

At first, he and the Hardys didn't see eye to eye at all and were almost always feuding, due to their conflicting views. He considered the Hardys to be just amateurs (and still somewhat does), while they didn't agree with his and the Network's often cold-hearted and violent methods (and still don't always). Gradually, however, they gained respect (albeit a slightly grudging one) for each other, and even became good friends over time, though (as said before) he still considers them amateurs and, in turn, they don't always trust him.

Samuel Peterson

First partner, Sam Peterson is the chief of police in New York City in the Casefiles series. When he and Fenton worked together they cracked some of the toughest cases in the department's history.

In Casefiles #5 Edge of Destruction he ran for Mayor of New York City, but had to pull out of the campaign because of heart problems.

Peterson lives with his wife in New York, and is a powerfully built black man, with graying black hair.

Brian Conrad

Brian Conrad is 17 years old, 6 feet 2 inches tall, weighs 210 lbs, and has short blond hair and blue eyes. He grew up in fictional Bayport, and still lives there with his family, in a small house. Unlike the rest of the houses in the area, though, the Conrad house is very poorly kept. He goes to the same school as Frank and Joe Hardy (the Hardy Boys of the title), Bayport High, with his sister Belinda Conrad. He does not like Joe Hardy at all and has a history of vandalism. He developed a soft spot for Frank Hardy, and treats him slightly better than he treats Joe.
