Mildew

Mildew is a light green alien fungus with powers of recovery, teleportation, recovery, summoning, and transforming.

Creating New Species Members
Mildew was originally from a unknown planet, left the sole survivor. He hitched a ride on a comet to Earth, where he got the technology necessary to create other new members of his species. He went to a uninhabited planet and created more Mildewians there who looked up to his as a sort of god. Mildew would make a close connection with his first creation, Mildew Jr. Eventually, the two had a falling out and Mildew pretended Mildew Jr didn't even exist.

Hosting KFANP
Mildew headed back to Earth and began hosting Kerfuffle For A Neat Prize, much to the jealousy of Mildud, leading to his making his own show. Mildew would generally be a lighthearted host, much to the annoyance of some contestants. He offered a 8 sided prism, or as he calls it, "A Neat Prize," and got 24 contestants onboard. When a contestant was eliminated, he would suck them into his pocket dimension. Mildew got turned blue to his Malberry allergy in KFANP 4.

Post KFANP
Sometime after KFANP, Mildew would regain his normal greenish hue and would go back to the other Mildewians and host Battle For Mildew, with the winner being Mildew Joe due to Mildud and Mildew Joe leaving for TMSS.
