Terrosurs are Plasma lieutenants from Darkspore. They resemble large, muscular, anthropomorphic red and black reptiles. Their primary attack is hurling three orbs of fire at the player. This attack can also deflect attacks directed towards them. Occasionally, they will summon Electron Bursters to aid them in battle. They are encountered primarily on the planet of Cryos.
- Terrosaurs have the same head as Maldri.
