Boxing Glove

Boxing Glove is a gun that shoots a limited-range boxing glove with a chance to stun. Each time it kills an enemy, it gains a star up to 3 stars. When at 3 stars, it can be charged to consume the stars and fire a high-damage super punch. It also increases curse by 1.

Trivia

 * This weapon's function is a reference to Mike Tyson's Punch Out!!. Its description is a reference to Piston Honda, one of the boxers in the game.
 * In later Punch-Out games, the character's name was changed to Piston Hondo, more closely matching the weapon description.
 * Like some other cursed weapons, the Boxing Glove increases curse because melee weapons are rejected in the Gungeon.
 * This weapon may also be a reference to the KO Cannon in Terraria.
 * This weapon is also a reference to the Super Monkey Ball minigame, where players repeatedly punch each other with an extending boxing glove and charging the glove makes it glow and releases a more powerful punch.
