Well, now or never, I guess.
Does anyone else look at the prototype slate and think the names are kind of blah? Don't you want something more exciting? More explosive? More combustible? More... BOOM? (Okay, I guess Bomshelk kind of does this, but meh.) Let us put this name submission stage on TURBO with the following final submission:
Nitropod
I suppose the full meaning of "gastropod" is nullified by using just the "-pod" suffix, but the point is, CAP 3 presumably stores combustible fluid in its shell, which is the whole reason behind its typing and attacks and such (okay, we haven't decided on attacks, but still). I also think that the fluid could also serve as a sort of life fuel for CAP 3, and hence the name could be interpreted as describing "one who walks using volatile fuel".
I was originally enamored with using the "ign-" prefix somehow, but nothing came to mind for it. This name came up instead.
...BOOM!
