The Power-Fist is a close ranged item, dealing moderately high damage with the cost of low swing speed and terrible range. It is also developed by Fluffy for the R0B0-B34R5 to have a weapon to defend themselves against Naughty Bear.
Naughty rapidly delivers a barrage of punches to the victim's face before delivering the final blow to the victim.
The Power-Fist has no suicide animation. Instead, the bear swells up like a balloon and pops.
