Airshock's Stupidity
It was surely very weird, existing as a hammering tool for a brute that wasn't much more intelligent than his Fighting Hawk was. Airshock had received his fair share of concussions, particularly when facing his muscular rivals, Stronghold and Rayzor. In fact, sometimes, Airshock couldn't tell the difference between his two forms, although when he could, he had to admit his bird form was preferable. This was simply because it felt better to be a bull-headed bird than to be a bull-headed hammer.
Take his word for it; use your brawn, not your brain.
That's just Mumbo Jumbo.
