Cyberchase is an American–Canadian[1] mathematics, environmental sciences, and meteorology cartoon that currently airs on PBS Kids. The show revolves around three Earth children (Matt, Jackie, and Inez), who use mathematics and problem-solving skills in a quest to save Cyberspace from a villain known as The Hacker. The three are transported into Cyberspace by Motherboard, the ruler of this virtual realm. Together with Motherboard's helper, Digit (a robotic bird), the three new friends compose the Cybersquad.

Each animated episode is followed by a live-action For Real interstitial before the credits, hosted by young, comedic actors who explore the episode's math topic in the real world. The show itself is created by Thirteen Education for WNET aka Channel Thirteen.

After the 5th episode of Season 8 in 2010, Cyberchase went on hiatus. However, on April 3, 2013, it was announced on the show`s official Facebook page that it would return for a 9th season during the fall.[2]

On February 10, 2015, Gilbert Gottfried, the voice of Digit, announced that five new episodes were expected to be broadcast in the latter half of that year as the show`s 10th season.[3] In April 2015, the show`s Twitter account retweeted a photo indicating that the season would focus on health, math and the environment.[4][better source needed]

In January 2017, it was announced that Cyberchase would be returning for an eleventh season, with 10 new episodes set to air later in the year.[5] In May, producer Kristin DiQuollo and director Meeka Stuart answered questions about the show in a 19-minute video.[6]

In October 2018, it was announced that Cyberchase would air for a twelfth season in 2019.[7]

Webisodes (2001, 2003, and 2005)[edit]

Preceding the televised animated episodes, in December 2001, three webisodes called "How It All Started" were added to the website.

  • Webisode 1 had 11 panels.[9]
  • Webisode 2 had 13 panels.[10]
  • Webisode 3 had 13 panels.[11]

By April 13, 2003, the trilogy was expanded into "Web Adventures", with a 4th webisode called called NUMBERLESS PUDDLES![12] which had 20 panels.[13]

On December 14, 2005, a 5th webisode called HACKER JACK was added,[14] which had 4 panels.[15]

The "Web Adventures" webisodes page was still up in December 2012,[16] but as of March 8, 2014,[17] it was changed into a redirect to the Math Games page introduced in 2011.[18]

Season 1 (2002)[edit]

In the pilot episode "Lost My Marbles", Hacker infects Motherboard with a computer virus. At a library on Earth, while looking at a computer, Jackie, Matt, and Inez (who accidentally let Hacker unleash the virus by touching the computer map at the same time) are sucked through an interdimensional portal into Cyberspace. In their first adventure, they go to an island to rescue Dr. Marbles. In subsequent adventures, they return to Cyberspace to thwart Hacker's evil plans, which vary from ruining Motherboard to trying to take over a Cybersite. Throughout the season, the Cybersquad searched for a new encryptor chip for Motherboard. In Episode 9, Buzz and Delete nearly retrieved the encryptor chip, but lost it in a dust storm, much to Hacker's frustration.

This is also the only season to use traditional cel animation, before switching to digital ink-and-paint which was used in Seasons 2–5, before finally switching to flash animation from the start of the sixth season to the eleventh season.

Season 2 (2003)[edit]

This season is a continuation of the same basic plot of season one. However, the focus on the search for the Encryptor Chip is shown less as the season deals more with a new scenario; each episode involving Hacker seeking to take over a cybersite or all of Cyberspace, or plot a nefarious scheme in which he is wreaking chaos and havoc somewhere. In addition, a continued appearance of Wicked, a witch from the cybersite Happily-Ever-After occurred, revealing her strong feeling towards Hacker, while Hacker only used her abilities as a witch to further his own evil tactics as seen in episode "The Wedding Scammer", although he did show mutual feelings towards her in "Harriet Hippo & the Mean Green", but once again, he became self-centered and cared less about her. In a way, the occurrences of "The Wedding Scammer" are the only of Wicked's evenings where she is successful with her affections. The character of Sam Vander Rom (Al Roker) is introduced in 204 and 208 and Erica Ram is introduced in 211, where she hosts Cyberscoop alongside him. In this second season, Hacker continues to run rampant, causing more chaos, and thus the Cybersquad returns to almost every Cybersite. The Wicked Witch also makes additional appearances. This is the first season to use digital ink and paint.

Season 3 (2004–05)[edit]

In the third season, the kids meet Slider, a rebel-style skateboarder who lives in the cybersite Radopolis. He first appears in the episode "The Borg of the Ring" where he retrieved the Totally Rad Ring of Radopolis from Hacker. Once again and then a third time Hacker tries to take control of Radopolis, first by almost winning a competition, then by putting everyone except Digit, Slider, and the Cybersquad asleep so he fails. The kids are told his father, Coop, had abandoned him. Coop was on a distant cyber-planet, but the kids didn't know that yet.

This season contains the first two-part episode of the series, "The Snelfu Snafu". While Slider was searching for his father, he stumbled across the location of the elusive encryptor chip. When he alerted the Cybersquad, they soon discovered it was in the hands of an auctioneer. The kids eventually earned enough snelfus (the Cyberspace term for dollars) to win it, but they discovered the chip was infected to drain Motherboard, replacing her with Hacker. The kids were then placed in the dungeon at the new Hacker Control Central; when they escaped, they searched for the encryptor chip because Motherboard was trapped in it. Upon finding it, they also rescued Dr. Marbles. However, when they attempted to put the chip in the circuits, the hardware rejected it because Hacker has corrupted it. Dr. Marbles was forced to reboot Motherboard, destroying the chip in the process. This concludes the Encryptor Chip story-arc. Also, Hacker rejects Wicked, setting the stage for some of the future episodes.[22]

However, the Cybersquad was able to thwart Hacker's plans again by dismantling the device so it could not be used again and allowing the effects of the Transformatron to wear off. This is the last season directed by Larry Jacobs, who had directed every episode up to this point.

Season 5 (2006–07)[edit]

At long last, Slider's dad comes home. However, simply because many of the parts used on the Transformatron before have disappeared does not mean Hacker has given up on it, so now the Cybersquad find themselves building, fixing, and inventing devices to stop Hacker from taking over. When the Transformatron goes on the loose, Digit and the kids must dispose of the NIC card, the only power source of Hacker's machine. New villains Olga (Annika Walter) and the Trashinator (Phill Collins) make their debut during this season.

During the season, a special two-hour program, "Cyberchase: My Big Idea!" was broadcast. The program comprised episodes 64–67 shown sequentially, and was oriented on the theme of inventions. Each episode covered a different invention topic. The program was hosted by Bianca and Harry from Cyberchase For Real! and in between episodes, they talked about inventions that were made by kids, and showed clips of kids who had made inventions of their own.

Len Carlson, as the original voice of Buzz, was replaced about halfway through the season by Philip Williams. Carlson died in 2006, and the episode "EcoHaven Ooze" was dedicated to him. This was the last season that was animated by Nelvana, before moving over to Flash animation by Title Entertainment, starting with season six.[citation needed]

Season 6 (2007–08)[edit]

Finally, the NIC card had been disposed of, which means that there are no more episodes involving the Transformatron. Unfortunately, Hacker hopes to expand his group of evil doers, now including Baskerville, Trashinator, and a gorilla named Tonga. With new allies for Hacker, the Cybersquad once again attempts to stop him. Meanwhile, love chaos ensues between Hacker and Wicked when Hacker starts to want Wicked back, but the Wicked Witch could want nothing more than to spit on him. This is the first season to use Flash animation.[citation needed]

This is the first season where Buzz is voiced by Philip Williams from beginning to end.

Season 8 (2010)[edit]

Season 8 premieres on July 2, 2010, and introduced Ledge (Alex Karzis), a fan of Hacker and was to get himself a place on Hacker's side to help take over Cyberspace. He tries to do so by making a machine that can turn everyone in Sensible Flats into "Hackerized" versions of themselves. Though this impresses Hacker, Inez eventually unplugs the machine, resulting an angry Hacker to cast Ledge away for his failure. This results with Ledge becoming Hacker's most dangerous rival. Aside from Ledge's failure, Hacker does not like Ledge because he heavily insults him and the possible fact that Ledge is less arrogant but more intelligent than Hacker, even though he is equally evil. The Cybersquad also does not like Ledge because of his deception that led almost all of them into danger in Sensible Flats he had caused by pretending to help them, as he thinks more wisely of his plans. It was then in episode 94, that Hacker and the Cybersquad were forced to work together to stop Ledge from stealing one of Hacker's previous inventions that can be used to help Motherboard, though the invention ends up being destroyed.

Though five additional episodes were announced,[citation needed] the following titles did not air: "The Dangerous CyberSpider", "DrainDroppers", "An Amazing Flying Shrew", "Hacker's Coin", and "Snowing in a Winter".[citation needed]

Season 9 (2013–14)[edit]

On April 3, 2013, it was announced on the official Facebook page that the show would return for a 9th season.[citation needed] The season premiered November 4, 2013, after being on hiatus since 2010. Issues in development for episode 95 caused some versions of the aired episode to air with the title "placeholder" cards in place. e.g. act 1, act 2, and act 3. In this season, Harley, Alicia, and Harry (from For Real) now work at Camp Henry teaching 8-year-old kids about the environment. Season 9 was animated in Flash by Pip Animation in Ottawa.[28]

Hacker wishes to build Hackerspace by drilling on Ecotopia. He captured an aged Doctor Marbles and stole his journal to help him locate the Reformat Button. In searching for the button, Buzz and Delete capture Ollie's mom Abby, and accidentally drill into the inner slime core. Hacker locks Doctor Marbles and Abby away while he recalculates the location of the button. Motherboard sends the Cybersquad into Ecotopia to investigate where the slime came from, and what they can do to help. They soon realize that many of the animals of the Cybersite have lost their homes due to the slime destroying 2/3rds of the Preserve. In order to fix this, they must install a new preserve and format it in a way that the animals can live comfortably, plus they need to relocate the animals. Using an ark they are able to bring the animals to the new preserve, but by just narrowly escaping a whirlpool. Soon after, the Cybersquad and Ollie notice that the orangutans are in the wrong portion of the preserve. In order to figure out why, Inez and Ollie return to the old preserve and examine the wildlife. But in order to do so, Inez must overcome her fear of bats, and Ollie must overcome his fear of heights. If that wasn't enough, they overhear Hacker looking for the button and realize he has caused the inner slime core to erupt. Ollie spots his mother with Hacker, so he desperately wants to save her. The Cybersquad and Ollie formulate a plan that succeeds in rescuing Dr. Marbles and Abby, while installing a lock on the Reformat Button, thus ejecting Hacker into Cyberspace. The movie finishes with Inez and Ollie enjoying a sandwich high up in a tree.

For Real: Harry shows 100 favorite moments of the series in honor of the 100th episode of Cyberchase.

Note: This is an hour-long two-part special.
