The Onslaught Variant of Underminds.

The Underminds are Plasma Lieutenants from parts unknown. Pyrokinetic zealots, the Underminds serve a support role to the Darkspore legions. Though they can easily kill a Hero on their own if they want to...
  • Onslaught Variant: Undermind
  • Invasion Variant: Pyrotechnic Undermind
  • Apocalypse Variant: Subversionist Undermind


While many assume that underminds emerged from the superhot domains of Cryos, no one knows where they actually evolved. Some suspect they're an original product of the Corruptor's mind, constructed gene by gene from a million different species. Whatever their origin, the cunning and craven underminds inflict damage on those who attack their allies, thus making them highly dangerous to engage. They attack foes with short-range lasers, and also heal their wounded allies.


The Underminds are dangerous on their own, and worse when with allies. Plasma Heroes are a liability here, as an Undermind can mortally wound them on a whim.

Tempests are the way to go. Their high Resist helps with the burns, and they can attack from afar. Tork's Sporogenisis can cleanse the Squad and all Allies of the burns and Energy Vulnerability. With Meditron, one can wait for the Undermind to have its say, then use Syndrome Shift.

Of course, if a Hero has a piece of gear that renders them immune to Burns, then all this is irrelevant. The Undermind will be rendered useless, allowing you to pick it off at your leisure.


  • Underminds have Char's feet and Lumin's hands.

  • Due to their head being made practically completely made out of "details", their real mouth remains unknown.
  • Note~ On Onslaught, there is a Mini-boss Undermind named Kaai the Craven Blaster. It has the Persistent and Persistent Aura buffs. It is encountered on The Desert Necropolis. During Invasion, Underminds are much more powerful and are known as Pyrotechnic Underminds. The Mini-boss of these new enemies is called Pretor the Pyro Incinerator. It has the Persistent, Persistent Aura and Carapace buffs. In Apocalyse, they are even stronger, and are called Subversionist Underminds.
