Superman's got a lot of look-alikes. Even just in the DCU, there's Mon-El, Captain Marvel, Ultraman, and arguably Ultra Boy. Branch out a bit and you find Hyperion, the Sentry, Samaritan, Apollo, Supreme, Maxi-Man, and so forth.
So, who's your favorite? Which knock-off Kryptonian tops your list?
I'll answer somewhere in the comments, methinks.
