Behavior[ | ]

Phase 1[ | ]

Ultra War charges in from the side of the screen and has two attacks which he alternates between:

  • Throws a large, Giga BombGiga Bomb that deals contact-damage and explodes mid-air in a cross pattern that spreads across the entire screen, similar to Collectible Bomber Boy iconBomber Boy Bombs. The Bomb also releases a burst of 12 lines of 4 projectiles outward when it explodes. This attack is repeated 3 times.
  • Charges off-screen, then wraps around the bottom of the screen 3 times, creating 4 to 6 pillars of harmless light in alternating positions across the screen, from which large lava projectiles launch upwards with staggered timing.

Phase 2[ | ]

Ultra War dismounts from his hobby-horse and has two new attacks which it alternates between:

  • Chases Isaac, then lunges diagonally downwards in Isaac's direction. After, Ultra War releases 4 streams of fire in the cardinal directions as well as a small burst of slower moving fires in all directions. This attack is repeated 2 times.
  • Lunges diagonally downwards while holding a large bomb which explodes in a cross pattern that spreads across the entire screen. Ultra War then bounces across the sides of the screen 3 times while moving upwards before plummeting into the lava below. When Ultra War emerges, he creates 4 to 6 large lava projectiles that launch upwards with staggered timing.
  • Upon death, Ultra War explodes, which can damage Isaac at close range.

  • The lava projectiles can be slowed and knocked down with certain slowing items such as Censer and high knockback tears.
