Could someone enumerate the differences between the two? I know Gigastorm has the orange horn on his head rather than the flat orange panel, and I know there are some deco differences. If you look it up on tfu.info, there don't appear to be any accessories with Gigastorm, other than the Full-Tilt robot. If that is the case, it's a real shame; I think Gigastorm looks cool with that horn. Could someone shed some light on this situation?
