Strong Man is just the 1936 version of
Strong Mad. Except he doesn't talk, he just kinda growls and moves his eyebrows. And he can't move his legs. He moves around by sort of bouncing from side to side.
Debut:
Parsnips-A-Plenty
Also appears in
Ballad of the Sneak and in the Easter Egg in
StrongBadEmail/little animal.
