Java

Java is a fictional character appearing in American comic books published by DC Comics.

Java is the Neanderthal servant of Simon Stagg. He was first discovered by fortune hunter Rex Mason and revived by the scientific wizardry of Stagg Enterprises. Java was present the day that Mason discovered the Orb of Ra inside the pyramid of Ahk-Ton in Egypt. The Orb was responsible for transforming Rex Mason into the metamorphae known as Metamorpho the Element Man after Java knocked out Rex Mason in the presence of it.

For years, Java lusted after Simon's daughter Sapphire Stagg, but was unable to win her heart because she was in love with Metamorpho. This bred a bitter rivalry between the two; one that persisted for many years. Java even risked his life once to save Sapphire from a melting skyscraper, and was transformed into a petrified fossil for his actions. Stagg's scientific prowess saved his life and returned him to normal.

During a time when Metamorpho was believed to be dead, Sapphire relented to Java's persistent advances and married him. Java became the father figure to Sapphire and Rex's mutant son, Joey. Java was not an inherently evil individual, but his moral base had been compromised due to his constant exposure to the unscrupulous Simon Stagg. He was also extremely selfish when it came to his wants and desires. When Rex abducted Joey from Stagg Mansion, Java flew into a rage and was determined to kill him. Even Simon's command over him could not quell Java's emotions. Frustrated by the Neanderthal's rare act of defiance, Simon Stagg shot him in the head, seemingly killing him.

Java did not remain dead for long however. The means behind his resurrection are unknown, but he was seen once again several years later attending the funeral of Metamorpho (who at the time was believed to be dead).

During the "Brightest Day" storyline, Java was with Simon Stagg at his Canadian estate at the time when Metamorpho persuaded him to help him and the Outsiders get back into the United States. Later that night, Java pays Metamorpho a visit while he was sleeping. For some reason, Java still had the Orb of Ra in his possession. Java uses the orb to knock Metamorpho around until Metamorpho becomes unconscious. Java then takes Metamorpho's body down to Simon Stagg's lab where he plans to merge him with Chemo. It doesn't go well as Java calls in Simon Stagg's servant Freight Train to help stop it. Freight Train manages to use an electrical wire which causes Chemo to vomit out Metamorpho. Simon Stagg later placed Java's mind into the body of a Shaggy Man which was defeated by Freight Train.

In 2011, "The New 52" rebooted the DC universe. Java's history with Simon Stagg and Rex Mason remains the same.

Java was present when Simon Stagg had opened a portal to the Dark Multiverse and is trying to close it with Metamorpho who was transmuted to Nth Metal. He is present when Mister Terrific, Plastic Man, Metamorpho, and Phantom Girl return from the Dark Multiverse.

Java was revealed to have been operating as the villain Doctor Dread and has formed a counterpart of the Terrifics called the Dreadfuls. They were defeated by the Terrifics.

Java in other media

Java makes appearance in the two-part Justice League episode "Metamorphosis", voiced by Richard Moll. Like the comics, Java serves as Stagg's assistant. After an unsuccessful presentation of his new "Metamorpho" project, Stagg ordered Java to transport valuable mutagen samples by train. He was told not to let the briefcase out of his sight, but one of the attendants checked it into the luggage compartment, citing regulations. One of the vials broke, damaging the carriage and causing it to derail until the train was stopped by Green Lantern. Stagg reprimanded Java for this failure, as it drew unwarranted attention to his operations. True enough, Stagg hadn't finished when Rex Mason inquired about Java's presence on the train. This and the fact that Mason was seeing Stagg's daughter Sapphire led him to test out the Metamorpho project on Mason. The morning after, Java accompanied Stagg to Mason's hospital room. After learning what had happened, Rex went mad, but Java could not stop him and was knocked out with a bed pan. Following Mason's trail, Stagg was eager to get pictures of everything, using them to pit Mason against his old friend John Stewart. After reviewing the success of his designs in battle, he sat back to consider the military applications, but Mason caught on to him and easily dispatched Java. Down but not out, Java reached for a canister of liquid nitrogen and froze him. Java oversaw Stagg's attempts to refine the Metamorpho mutagen when Metamorpho barged into the lab. This time, Mason went straight for the nitrogen, knocking Java into a cabinet. In Mason's fight with Stagg, a giant synthetic creature was released, which destroyed half the laboratory. Java was able to get out before Green Lantern and Batman investigated the place.

Java appears in The Flash episode "Fastest Man Alive", portrayed by Michasha Armstrong. This version is an African-American who is the head of security for Stagg Enterprises. Danton Black paid him off so that he can attack Simon Stagg at a university gathering that was honoring him. Later on, Danton Black tried to get Java to grant him access to Simon Stagg's house. Java refused and punched Danton when he threatened him. In retaliation, Danton multiplies and beats Java to death.

John Wilson, also known as John Henry, is a fictional DC Comics superhero.

John Henry was a veteran of the Korean War. After the conflict, Wilson discharged and took work in a local machine shop and settled down in Knoxville, Tennessee with his wife Lucille and baby daughter Loretta. On the night of March 17, 1955, John and his family were attacked by the local Ku Klux Klan. He was lynched and his family was burned to death. After the Klan left, John survived his lynching. Devastated by the death of his family, John followed the Klan members. John then forged two iron sledgehammers and became the vigilante known as John Henry. For three months, John plagued the Klan and had killed two Klansmen in his crusade. John Henry's reputation attracted the news media and remained a hot staple on the public, including the Martian J'onn J'onzz, who considered him an actual American hero.

Tragically, John was wounded by the Klan and stumbled into a backyard. He was discovered by a young white girl, who outed him out despite John's pleading for help. Once caught he was burned alive.

However, his death didn't go unmentioned and his endeavors was highlighted in the television news show The Big Picture, which its host extolled Wilson's stance against racism and criticized the American government for ignoring the serious issue. J'onn J'onzz saw this and was very dismayed of Wilson's death, which contributed his demoralizing faith for humanity.

Following the defeat of The Centre, a young John Henry Irons sat reading near John Wilson's gravestone.

Rhea Jones

Rhea Jones is a fictional character appearing in American comic books published by DC Comics.

Rhea Jones was the daughter of an Air Force official. After tagging along with her father to a government base in the Arctic, an explosion involving a powerful radioactive electromagnet killed her father and granted her electromagnetic abilities. Rather than stick around and be dissected and experimented on by the army, she ran away and joined the circus. After a few years, Rhea was recruited by Arani Caulder to join her new Doom Patrol.

After being recruited by Arani Caulder, aka Celsius, Rhea was now one of three new recruits into the Doom Patrol, along with Scott Fischer and Wayne Hawkins aka Karma. Celsius gave her the codename Lodestone. Her demonstrated abilities allowed her to fly, give herself Earth reinforced superstrength, create limited force fields, and attract or repel metallic objects like bullets.

Following the Invasion! storyline, Rhea and Scott were struck by a disease created by the Dominators. Her powers went wild, and then she lapsed into a coma, but ultimately she lived while Scott died.

At the start of Grant Morrison's surrealistic run of the Doom Patrol, Rhea was put into a coma that would last until halfway into the series. While in the hospital, she was kidnapped by the butterfly collector known as Red Jack, who claimed to be God, Jack the Ripper, and many others. He sought to make Rhea his bride. The new Doom Patrol followed Jack into his house, which our world is a room in. As he battled the Doom Patrol, Rhea awoke from her coma and stabbed Jack in the back, then immediately became comatose again.

Brought back to the Doom Patrol's new mountainside headquarters, Niles Caulder, the Chief, did experiments on Rhea showing that her coma wasn't normal. She was instead going through a form of metamorphosis, and her human form is the chrysalis.

Rhea awoke from her coma in issue #36 during "The Orthodoxy/Geomancer War". It was revealed that she was The Pupa, a weapon sought by the aliens Orthodoxy and Geomancers. Rhea's original body shattered, and out emerged a magnetic butterfly, explaining why she was sought out by Red Jack. After awaking, her facial features disappeared and her eyes were now on her chest and back. Her ears had also become two twinkling lights. She no longer wears clothes and seems to think nothing of it.

Rhea was actually what some call a Lodestone, a being in tune with the Earth's electromagnetic waves, its nerve system. They are the Earth's expression in flesh. The Ultraquist Geomancers kidnapped Rhea, and Rebis in the process, before she was able to fully bond with the Earth.

After ending the conflict between the Orthodoxy and the Geomancers (with help from Rebis and Robotman), Rhea pointed out a bright star in the sky, and left to go visit it. Promising to visit, she has not been seen since. Her only subsequent appearance to date has a brief flashback to her early days with Arani Desai and Valentina Vostok when the two returned during Blackest Night.

Rhea Jones in other media

• Rhea Jones makes a cameo appearance in the Batman: The Brave and the Bold episode "The Last Patrol". She appears on a poster advertising a carnival's freak show.
• Rhea Jones / Lodestone appears in the Doom Patrol episode "Doom Patrol Patrol", portrayed by Lesa Wilson as a young woman and an uncredited actress as an old woman. This version was a member of a 1950s incarnation of the Doom Patrol before they were defeated by Mr. Nobody and disbanded. As most of the team were left mentally ill following the battle, Joshua Clay became their caretaker.
