I liked Black. He was a fun character. This never got explored, but Blue and Black were actually twins, separated in their infancy. I know, Black and Blue, right? 01 is also very clearly Hypotenuse Man, who was a character I used as my avatar for a long while.
Azure's interactions with Marx are still some of my favorite parts of the reboots.
