(Quick note:  I realized after drawing the armor that the proportions are way off.  The head should be a lot smaller compared to the body.  When I draw him again, I'll fix that.)

SO!  This is what Cato's armor looks like!  As opposed to normal protogens where their armor is attached to their bodies (or at least I presume that's how it is), Cato's armor is actually a suit that can be taken off.  Therefore, I didn't want it to look like a normal protogen suit.  I wanted it to be like a combination of the typical protogen suit and the Iron Man suit.  You can easily see the inspiration with the chest light and the hand lights.  It also is fully weaponized and has pretty much all of the features of the actual Iron Man suit.  (The only thing it doesn't have is Jarvis, but Cato himself is pretty much Jarvis.)
I normally HATE drawing armor, much less DESIGNING it, but I'm actually pretty satisfied with how this looks!
