He is roughly the same height as Thor but in MUA he towers over Thor. They should have switched these two around height wise. I realize on the pc this can be modified but on the consoles, nope.
According to MDB, Cage and Thor both are 6'6'', as is Colossus. I believe that Luke Cage is probabaly augmented in his height because he is a bruiser, as Juggernaut is at 6'10''. But then again, MDB states that Thing is only 6'.
actually Colossus is 7'5" when he's transformed...
