Aeon and Lizardman are the same character tho. It's just the fighting style that differs between games, unless you're referring to the generic Lizardman that was in SC2...
I actually though that Lizardman was in SC2 and also SC3, but seems no for this last game. So actually i just checked so basically Aeon has always been in all SC except SC2 where it was Lizardman. Interesting didn't know about this lol
