Before the Darkspore mutated Scaldron's entire biosphere, four-footed crater mites lived humble lives, attaching themselves to larger creatures and consuming their sloughed-off skin cells. Following transfection, the crater mites became novas, oversized homunculi with highly unstable metabolisms. When their fight-or-flight reaction is overstimulated, novas quite literally explode, engulfing any nearby foe in a highly destructive, flammable mucus, so viscous that it's nearly impossible to remove. By fleeing, foes feed more oxygen to the flames. Few creatures of their size inflict as much damage as novas do.
Their main and only ability was to run towards the nearest hero and explode violently, covering all nearby heroes in a flaming mucus that actually increased in duration the more they moved around. The burning effect would cause very high damage over time. If they appeared in large numbers, this could be deadly. If you got hit by them and could not switch heroes, standing still or having Meditron's Syndrome Shift or Tork's Sporogenesis was a good way to end the debuff.
A good way to prevent them from coming to you was to use Andromeda's Repulsion Sphere, Gravity Storm or Force Pulse, plus all her variant abilities minus Shooting Star.
