Hacker (Adventurers: Masters of Time)

The Hacker is the main antagonist of the German-Britsh cartoon show Adventurers: Masters of Time.

Section heading
The man only known as the hacker was able to get his hands on a program invented by computer scientist Professor Krupnik which allowed him to travel through time. However, the hacker doesn't do the time travels himself, he rather sends two artificial beings who are tasked to alter the past for him while he monitors them in his lair. Mostly, those plans include major historical events, be it the sabotage of a play by Shakespeare, the destruction of a launching space shuttle or preventing the birth of Richard Lionheart by preventing his ancestor's marriage.

However, all of the hacker's attempts are stopped by Krupnik's students Fire, Paul, Kevin and Nikko who found a talking time travel device when looking for Krupnik, who seemingly had disappeared, but is able to give them instructions from afar.

Every episode of the show portrayed the hacker doing things almost the exact same way: At the beginning of the episode, the hacker activates the avatars and sends them to some point in world history to sabotage an event. He himself monitors their actions on a screen and occasionally comments on them. At the end, when his henchmen got defeated by the kids, he calls the avatars back to his base and yells at them before shutting them off again.

The only difference in this perpetual plot was the last episode before the show was cancelled: After his attempt of blowing up the Sphinx during Napoleon's conquest of Egypt failed, the Hacker revealed that Professor Kupnik was his prisoner.

Trivia

 * The Hacker's identity was never revealed as the show was cancelled.
 * Due to them having similiar arms, it's possible that the recurring Professor Grumer, another of the student's teachers who was constantly fooled by them into ignoring his suspicions concerning them having done something else in an incredible short amount of time, was the hacker.
