Red-Brief J

Red-Brief J is a boss in the video game Wario World. Named after his attire, Red Brief-J is a large, bipedal, anthropomorphic bull. His body is covered in a few scorch=marks and the top of his head and horns are made out of pure steel. The boss of Thrillsville, players face him after clearing Beanstalk Way.

Red-Brief J has the largest variety of attacks of any of the bosses in the game. Before he starts any attack, he will strut around after Wario with his hooves on his hips. Wario must not go near his feet when he does this, because fire erupts from them while he's walking. In his first and most common attack, he absorbs orange energy and charges toward Wario at full speed. The number of charges equals six minus the current HP. His second attack is to point and shoot homing fireballs from the hooves on his arms. His third attack only happens when he has taken damage. It involves drawing in purple energy and jumping extremely high, then landing at the middle, briefly dunking half the arena in lava. Stand on the middle area to avoid this attack. His fourth attack happens when he's on 2-3 HP. He jumps in the air and starts spinning while drawing in blue energy. He starts front-flipping and then dives head-first into Wario. In his final attack, which only happens when he's on 1 HP, he draws in pink energy and spins like a ballerina towards Wario. This attack has an extremely effective homing ability, so it is very tough to dodge.

To defeat the bull, who is invulnerable to Wario's punches, Wario must wait for Red to do one of his huge charges. If dodged just right, the hulking bull would lose control and end up teetering on the edge of the arena over the lava. When this happens, Wario must immediately Ground Pound the middle section of the stage, causing Red-Brief J to fall off. Should Wario continue to assault Red-Brief J up close with his punches, the boss will counter-attack with one of his available attacks. After five dunks in the lava, Red-Brief J succumbs and Wario receives the third Giant Treasure Chest Key.
