(to be edited in relation to this list).
Miracle (marvel) man: "KIMOTA"
@thor_ul: Absolutely! I was going to go with all the magic word speaking guys I could think of, but changed my mind and went with DC characters only. Since Miracleman is Marvel, I left him off.
I'd put Zatana higher on the list.
Also, no He-Man "By the power of Greyskulll. I have the power!"?
@stumpy49er: It wasn't really a ranking- I just added characters as I thought of them. Of course, some of them are speculation leading towards fan-fic. ;)
