This creature is from the original, 1998/99 HλLF-LIFE video game. For more context you can refer to those two articles :


  • Base Of Operations: Xen.
  • Size: About llama-sized.


Powers and Abilities

Bullsquids aren’t too bright. They’ll hole up in a dark corner and attack anything that comes by. They can use their fine sense of smell to locate invisible/stealthy targets.

Bullsquids will close on their prey, spraying them with acid until they close to hand-to-hand range. Then, they will use their tentacles (in DC Heroes RPG terms, Claws).

It is theorized that their actions do not indicate an attack behavior, but rather a mating behavior. This has not been confirmed, however.


The Black Mesa complex is a private high-tech research installation (with strong ties to the U.S. government) located somewhere in the American Southwest. An accident in the Anomalous Materials Lab caused a dimensional breach into the world known as Xen.

The bullsquids were among the creatures to fall through the breach into our reality.


A large, bipedal slug with tentacles circling its mouth that spits mildly hallucinogenic acid. That pretty much sums it up.


Sits around and attacks (or attempts to mate with) anything that moves.

They are the natural predator of the headcrab and will attack them on sight, often ignoring more potentially deadly enemies.

DC Universe History

This would be a moderate-level threat to the Earth, probably a good challenge for Young Justice or a similarly-powered team. It might be a good solo challenge for Batman.
