They're both different adaptations of the same character, but comics Slade Wilson could probably brutally murder and torture Teen Titans TV show Slade Wilson in a thousand different and horrendously terrible ways in under 3 seconds of battle.
The Teen Titans TV Show was still awesome, though.
@josephandersonofindia: Welcome to comic vine and those two pics are different versions of the same character. Second pic would win. Also contact one of the mods to bring this thread to the battle forum.
