Freakazoid

Freakazoid is the titular main protagonist from the Freakazoid series.

Freakazoid is born on Christmas Day when Dexter Douglas entered a computer code by accident, activating a flaw in his brand new Pinnacle computer chip. He was suddenly zapped in the computer, where he absorbed the knowledge of the Internet and gained superpowers. His initial transformations were unstable and unpredictable, but Dexter soon learned that he could change into Freakazoid by saying "Freak out," and back to Dexter by saying "Freak in."

Personality
Freakazoid possesses all the knowledge of the Internet, but at great cost to his sanity. He behaves in a very silly fashion, and often defeats villains in unorthodox ways, such as subjecting Longhorn to the seventh inning stretch, or getting Cobra Queen to say tongue twisters until she passes out (Freakazoid admits that he has no idea why this worked). He also frequently breaks the fourth wall and is very aware that he is on a TV show. When  Freakazoid  breaks character on-set, he tends to talk in a voice similar to Jerry Lewis's "serious" voice.

Although Freakazoid and Dexter share the same body and also seem to share one another's knowledge, they seem to be separate entities. For instance, Freakazoid wishes to cut Dexter out of the main title of the show, and gets annoyed when an episode spends too much time with Dexter. Still, Freakazoid sympathizes with Dexter. He likes to wrestle with Dexter's brother Duncan Douglas in revenge for Duncan's bullying of Dexter, and initially tries to get Valerie to like Dexter (before deciding to be shallow and just letting Valerie kiss him as Freakazoid).

When Dexter isn't Freakazoid, Freakazoid spends his time in an area of Dexter's brain called the Freak-a-Zone, where he reflects, has profound thoughts and watches Rat Patrol. Freakazoid sometimes speaks to his inner child, whom he has named Billy. Billy claims to have grown quite large.

Freakazoid loves hospital water, but hates hospitals, because they store blood in refrigerators. He occasionally picks up some off-the-books additional cash by doing skywriting for the Happy Clown Cafe. His favorite ancient race is the Ancient Egyptians, partly because you can't even see the spackle in their buildings.

Abilities
Super intellect: Freakazoid has all the knowledge on the internet, but because of the ever-increasing knowledge gathered there, it leaves him mentally insane.

Superhuman Strength: Freakazoid has a varying degree of suprehuman strength, sometimes only slightly stronger than normal people, while at other times stronger than Cave Guy.

Superhuman Speed: Freakazoid can move at light speed, for example when he once crossed the globe in mere moments to yell at a Tibetan monk for raking too loudly.

Cartoon Physics: Freakazoid can impart the laws of physics in absurd ways to a level that even rivals those of Animaniacs.

4th Wall Awareness: Freakazoid has the knowledge that he is in a television show and that a audience watching him, he relatively often communicates and interacts with the audience who watch him, or the people animating him.

Telekinesis: Freakazoid can in very rare cases use telekinesis in a state of high anger. He only shows this feature in "Two Against Freak".

Trivia

 * Freakazoid was designed by Bruce Timm.
 * Mike Allred, creator of the comic Madman, has claimed that Timm told him Madman was an influence on the design of Freakazoid.
 * When Timm left the project, Tom Ruegger was brought in to develop the character and came up with the madcap personality.
 * Paul Rugg started as a story editor and writer on the show, but also became the voice when all of the auditioning voice actors were trying to be too manic and do a Robin Williams-type shtick. The producers were unable to give the auditionees any feedback, since they had no idea what voice they wanted; they simply knew that they did not want the version of the character they were hearing in auditions. Finally, in hearing Rugg give readings to the auditionees, Ruegger realized that he should do the voice. Rugg auditioned for the role by reading the episode "Dance of Doom" and improvising extensively between the scripted lines. The tape from that audition became the final audio for the episode.
