Combat Pragmatist: Victim is this, much more so than his successor that appears in the sequels. To be fair, noogai created this iteration of the Animation specifically for torture (aptly naming it "victim"). It's only natural for this little guy to come up with some dirty tricks to fight back.
His Name Is...: The Animator's programmer friend was just about to reveal how to stop the Chosen One when AIM was killed.
Hoist by His Own Petard: AIM is killed when the Chosen One throws the open AIM window at him.
Shock and Awe: The Chosen One, again. Burns the Flash 8 icon with a storm cloud's lightning bolt.
Serial Escalation: In-universe example; When the Animator goes over what power level to make the new Animation, he goes through "victim", "killer", "BEAST", and finally stops on "The Chosen One".
On a more meta level, the Animator. It's pretty clear that as villainous as he may be, he's pretty much defenseless and is merely trying to survive The Chosen One's Roaring Rampage of Revenge.
Hoist by His Own Petard: The Dark Lord and the desktop icons may have stood a better chance of winning had the Animator not left a game of Minesweeper open.
Screw Destiny: The Dark Lord's very purpose in life was to destroy the chosen one. They eventually team up to get revenge on the animator.
Shout Out: Pitting together the Chosen One and the Dark Lord is, of course, one to Harry Potter.
Stop Helping Me!: Subverted. You'd think Clippy offering his help to the Animator would be quite ineffectual like in real life, but he turns out to be a surprisingly competent fighter.
