I chose Gum-Gum Jet Rifle.

I wanted to say jet rifle, but then I saw get red hawk...

I was confused for a second and thought jet hammer was jet axe which is my favourite gear 2 technique. It's always funny to see him raise his leg so high and crush it on someone. From tge options I'd pick jet rifle.

Red Hawk

Red hawk most likely

Rew Hawk but I like the others too

Red hawk for sure
