Mac

Mac is a character hailing from the Foster's Home cartoon, debuting in SBF2.

Biography
Mac was a very pessimistic child when he arrived on the show, both towards the people around him, and in the challenges, due to him barley trying in any of them. He had come close to death twice in the series, barely edging out King Dedede in "Brief Construction Montage", and again in "Drive the River Down". Most people on the show hated Mac except for Byron, who revealed that he thought of Mac like his second son. The two spent most days digging and mining for minerals, since Mac claimed he had nothing better to do.

His depressing and pessimistic attitude was unknown for a while, until the episode "Drive the River Down", where he reveals to Byron that his friends and family had died in a wildfire, and according to Mac, he was the one that started it. He then reveals that his purpose for joining Total Moonman was so that "he could walk away with cash, or finally end it all". Byron is able to talk him out of this goal, but only slightly helps Mac in the longrun.

In "The Boy Who Cried Rainbow", Mac gets the real wake-up slap to end the pessimistic attitude from Rainbow, when she talks some sense into him with her own story about her rough life as a child. This significantly helps Mac, and the two separate. Later in the episode, when Rainbow tries to punish Kneesocks for cheating, Mac is hit with the permanent serum instead, causing him to turn into a Weavile. However, Mac is ecstatic at the result, now knowing that he can start a fresh new life. Rainbow then takes him off the show and back to her facility for further study, resulting in his elimination.

He returns in the finale of SBF2 alogwith Raiinbow, where his only purpose for arriving was to kill the loser of the challenge. In this case, it was Kneesocks. Due to their previous meetings, Mac had little to no problem with mauling the demon to death in the episode.
