Little Mac is the main villain and final boss from the fangame Abobo's Big Adventure. He is revealed as the mastermind behind Aboboy's kidnapping, after Abobo kills Kirby and saves Doc Louis. Little Mac wanted to prove that nobody could stop him, so he ordered his goons to kidnap Aboboy and stop Abobo.

Little Mac is fought on the Punch Out level, which is also the last level. After taking some punishment, he paralyzes Abobo and uses a secret "?" box with many power-ups, transforming into a super-muscular form called Big Mac. After being defeated, he loses all power-ups and returns to his normal self, so Abobo decapitates him with the NES Power Glove.
