Ah yes, the giant evil roomba, for some reason these scared me which is why I never played Sky Rail in multiplayer

Still looks good, though. This is my favorite GUN robot, not really sure why.

Like the others, these are made relative to the size of Sonic's Genesis sprites in comparison to their relative size in the game itself, but are not necessarily "Genesis style" themselves. The "treadless" ones are for charging, and there's more turning frames than the others simply because they turn fairly slow. I know the spikes on Rhino Spike are off from how they appear in game, but I decided that having them tilted different ways probably wasn't worth the effort since it's a minor detail. Rhino Spring from Sonic Rush is not included because it looks too different; I may make a separate sheet for the Sonic Rush GUN robots later. Regardless, my next focus is the Hornet series.
