Atari Strong Bad
From Homestar Runner Wiki
Atari Strong Bad is the form Strong Bad takes when he appears in Atari 2600 games and related places. He is also in the upcoming Homestar Runner RPG for the Atari 2600, as the villain. He appears to be able to speak normally, though so far all he's been heard to say is "I wanna get this freakin' duck away from me!" In addition to his more lifelike form, Strong Bad also appears as a single red dot in Secret Collect. He claims that this dot only looks "kinda like" him.
