Incrediboy

Buddy Pine, also known as Syndrome and Incrediboy in his youth, is the main antagonist of the Disney/Pixar film The Incredibles. He is Mr. Incredible's "biggest fan" and a megalomaniacal tech genius.

How The Incredibles Should Have Ended
Buddy is first seen meeting with Mr. Incredible as the latter confronts Bomb Voyage. As Buddy unveils his jet boots, Mr. Incredible begins to tell Buddy off, then realizes that Buddy's gadgets can be beneficial. He decides to meet with Buddy in a few days to talk.

Fifteen years later, Mr. Incredible explains to Batman and Superman that he recruited Buddy to be his benefactor and sidekick. As Buddy flies by, Mr. Incredible remarks how different things would be if he turned Buddy down. The scene then changes to Buddy as Syndrome at the Villain Pub.
