Oh dear lord, I once created this ridiculous AU when I was in high school for my character Mr. Blueberry

He's the guy on the right. He has weird purple skin, an eye patch, and he is missing his left arm.

I make an AU for him (called The Merman). In the AU, the world implodes on itself, which kills the mass majority of the population. Mr. B finds a safe floating island in the sky and lives there with a bunch of other people, the island then at one point falls into the ocean and becomes a regular island. He finds a wife there and tries to start a family however, he falls into a deep depression because all his friends and family from earth are dead. He then can't take it anymore and commits suicide by jumping into the ocean. However, it didn't kill him (hence the whole merman aspect) but he stays down there for years in a weird coma. When he emerges onto land, he's cured of all his defects, so no one really recognizes him. He then comes across his two daughters, one who has gone bonkers and the other who was raised as a boy and has an identity crisis when Mr. B tells him that he was born female. Then there is something about racism and how Mr. B stands up against it....OK, the whole thing was really weird and I have no idea why I came up with it.
