If mutations are the efforts of evolution, that would make Wolverine the perfectly evolved human.
He's not the strongest, but I guess he really is the perfect one.
In term of survivalibility.
And that's what evolution is. Survival of the fittest.
And speaking about Wolverine, I suddenly remember that Archie has a Wolverine variant of Sonic.

I came up with a backstory... but I dunno if it will be liked.
He was once the daughter of a monastery-like hive colony. She and all her other sisters are the same and must collect flowers to be made into honey for their queen-mother.
One day, Charmy flew far from the colony in search of flowers and ended up on Newtrogic High Zone where she got captured and held with Knuckles, Vector, Mighty, Heavy and Bomb.
Despite the predicament, it was the most excitement Charmy ever had! The others mistaken her for a boy, but "it felt right for him" that he never said otherwise on the matter and wanted to be part of the lads.
After the Metal Sonic Kai battle, the Chaotix Crew was formed with Charmy. (Perhaps later Mighty left the Chaotix Crew and they rebranded as Team Chaotix).
That would be my story for Charmy. The reason I figured Charmy is kid-trans is that worker bees are identified as female and Charmy has a stinger and an affinity for flowers.
The story is good I guess. The thing is Charmy is already disliked by many fans.
Making a him a kid-trans character will be a problematic since it would serve as a fuel for homophobic fans to bully the character even more.
