Professor Worminkle

Professor Worminkle is the true main antagonist of Worms 4: Mayhem and Worms: Ultimate Mayhem, who plans to train your team and use them to help him to achieve his goal to take over the world. In the first part of the Story, he only seemed to be a good mentor, but he acts quite strange sometimes, hiding his evil plans. In the cutscene before the mission "Fast Food Dino", he takes your team to the prehistoric era after he discovers you reading a sheet of paper explaining his evil plans and leaves your team there to die. However, the Professor's Time Machine crashes into a mountain on an island while he was heading for home after he betrayed your team and he was trying to repair it ever since. In the final mission, your team finally catches up with the Professor (with the Time Machine almost fixed), who is still on the mountain trying to fix the Time Machine. The island he's on is full of Dino-Worms. After the Dino-Worms are defeated, the Professor finally fixes the Time Machine, and when your team reaches his location, he thinks your team is going to save him and go home with him, but your team still wants revenge after the Professor betrayed them. So your team gets in the Time Machine and goes back home without the Professor, leaving the Professor in panic and stranded on the prehistoric island forever, and the world is saved.

The Professor is one of the most evil and intelligent villains of the Worms series. Also, the Professor has a friend named Mike who appears in the mission "Mike's Secret Laboratory". The Professor describes Mike as "his brightest pupil". It is possible that Mike was secretly helping the Professor achieve his goals.

Personality
Professor Worminkle is a manipulative mastermind. He is very intelligent, but also cold and heartless, since he makes you do all the work just so he can achieve his own goals and leaves you to die after all you've done for him. Also, in the description for one of the Story missions, the Professor claims that he's a pacifist, which is why he doesn't help your team battle the enemy Worms throughout Story Mode. But it's possible that he was lying.

Physical Appearance
The Professor is quite old. He is mostly bald and has some white hair around his head, he has a white mustache, and he wears half-circle glasses. He also has an unlockable flag called "Prof", which is basically a picture of the Professor. His hair, glasses, mustache, and flag can be unlocked if you complete Story Mode.

In Facebook Worms
Professor Worminkle also briefly reappears in the Facebook version of Worms, where strangely, he teaches you how to play and is your first opponent, although in Worms 4: Mayhem (and Worms: Ultimate Mayhem) he was your main enemy and was left stranded on the prehistoric island. He also appears to be much friendlier in this game. However, it could be possible that the Professor in this game is not Worminkle, since he is simply refered to as "Professor" and not "Worminkle" (and since Worminkle was stranded on the island forever), but this is unlikely since the Professor in this game strongly resembles Worminkle.

Trivia

 * In Worms 4: Mayhem and Worms: Ultimate Mayhem, the Professor is sometimes refered to as "Prof". "Prof" is also the name of his flag.
