Ooh, teal is my favourite. For teal:
- everyone is infected by the monster thing, only it is seen as a good thing. Society has adapted to the change, and the new powers are seen as 'the next step in human evolution' Sasha is seen as a saviour type figure, as he was the 'original'. Izea can either agree with the majority or hate what humanity has become.
-monsters haunt the streets at night, terrorizing anyone who is out at night. Izea is one of the few who knows how to kill them, but he is a recluse who hates himself for killing his best friend.

I might be able to think of more, but for now this is all I can come up with
