User blog comment:Tacozilla99/Who would win, Gigan (millenium) vs Legion/@comment-1030114-20160116113605

Legion can open her horn and disrupt mechanical systems with her radio wave blasts, as well as cause destruction. When her horn gets torn off (which given the fact that Gigan uses bladed weaponry, that's almost a certainty) she can release tentacles that cut through anything.

I'd say Legion's going to win with this one.
