Prince Bully is a boss that first appears in Super Mario 3D World as the enemy of the World 6-A: Prince Bully Blockade. He is a large Bully with red feet, made out of silver metal with large, gold horns. The fact that he has a crest of red feathers like those of Corinthian or Gallic helmets & that he also spews fire from his stove-like mouth makes him a half centurion helmet & half furnace.
Prince Bully appears as the Enemy Blockade of World 6 (World 6-A: Prince Bully Blockade). Like other Bullies, he will attempt to ram into the player. This will not damage the player, though. If the player retaliates by ramming into Prince Bully, he will spit out a fireball that will damage the player.
In the second encounter in World Castle-B: Prince Bully Blockade Is Back, Prince Bully (who has probably strengthened himself & done a self-promotion) has blue crest feathers and blue shoes instead of red ones. He also spits out three blue fireballs instead of one and the amount of fireballs will increase by one each time he's damaged, but his general attack pattern is similar to the first encounter.
In both encounters, the player should force him into a nearby Clear Pipe, where he gets sucked in & spat out by another, rolled into a cylinder, at which point he must be pounced on, throwing him across the room. After three hits, Prince Bully is defeated and a Green Star will appear.
