Behavior[ | ]

Unlike the other Ultra Harbingers, Ultra Death has only one phase and has three attacks which he cycles through indefinitely:

  • Summons a rectangle of 11 Ultra Death ScytheUltra Death Scythes which close in towards Ultra Death's position and continue in the same direction until disappearing off screen. Ultra Death uses this attack 3 times in a succession.
  • Flies off screen, then reappears travelling slowly while summoning waves of Ultra Death HeadUltra Death Heads which move up and down across the screen in the same direction. At the end of the attack, the skulls freeze in place and Ultra Death summons three harmless scythes which spin outwards, destroying the skulls.
  • Immediately after the previous attack, the screen darkens and Ultra Death disappears into the darkness. Ultra Death appears next to Isaac and swings his Scythe before disappearing again, darkening the screen with each attack. This attack is repeated 4 times, afterwards, the screen returns to normal and Ultra Death reappears.
    • His position during this attack can be indicated by a faint glowing red eye.

  • Ultra Death can be seen facepalming in the background after killing Boss Ultra War ingameUltra War.
  • The wave of Ultra Death Heads loosely resembles one of Boss Conquest ingameConquest's attack.
    • This could be compensation for Conquest's lack of appearance despite his Harbinger role.
