Blatantly stolen from Voice's idea to have this only with swords, just adding boxing gloves it's still a horrible ripoff on my part.
So I'll add this: You can actually control the speed of the fan so you can effectively duck and dodge your opponent's punches. Maybe even have the arms retracts or go
to a non position with less air flow.
Okay, thats a new addition. You actually control the boxing match so it's not just random flailing. Would still only need one fan, this would just be accomplished with flaps acting as valves into the chamber. Might even add control of the fan too so you could duck even lower.
I'd have multiple chambers too so you push the right fan button, the right arm punches, left the left punches. Back off both of them you duck, push both forward you lean forward.
