Dark Stalkers are creatures that inhabit the ground below Callisto.
Description[]
They have blue shells protecting their green bodies. They have four blue legs, and can run fast. Long, sharp teeth protrude from their mouths. They have the ability to phase through rock.
They are small, but hunt in large numbers. In these colonies, they can chase their prey airborne, and can even dig underground. They will chase and try to eat anything that enters their territory.
Callisto[]
The Dark Stalkers followed the Doom Hunter to Callisto, staying below to guard the entrance to the floating city. The Defenders make their way to Callisto, but are attacked by the creatures and Kara is separated from the others. Kara tries to run from them and is cornered, but Sari uses her staff to scare them away momentarily. The two manage to get away by using the elevator to enter Callisto, where the other Defenders are waiting.
After the Defenders defeat the Doom Hunter and claim the Pure Stone, they are ambushed by Brackus. Sari casts a spell and knocks Brackus off the ledge, which alerts the Dark Stalkers to their presence above. He is able to go through his portal before they attack him, but Sari is not as lucky when she is knocked off the ledge by Kara's attack, as the creatures swarm her.
