Half-Life geneworm monster



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


  • Group Affiliation: Race-X.
  • Base Of Operations: Xen.
  • Size: About 20′ tall, 50′ long


Powers and Abilities

Geneworm is the apparent leader of the Race-X forces. Geneworm’s greatest power comes from the loyalty of its numerous minions, but it also has considerable power of its own including great physical strength and the ability to fire radioactive blasts.

Geneworm can also bring nearby servants directly to it by finding them telepathically and teleporting them to its location for direct support.


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. Geneworm is the leader of the Race-X forces and, unlike Nihilanth (who led the Xen forces), actually attempted to enter the Earth dimension.


Geneworm resembles a giant green squid with glowing yellow eyes and a pickaxe protrusion from its forehead. The latter greatly resembles a Xen tentacle’s head. When it opens its mouth a glowing purple teleportation sphere can be seen within, much like Ultron’s ionic furnace glows within his mouth.


Emerge from dimensional gate, scream and break stuff. Start teleporting in Shocktroopers as its ass is getting kicked.

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.

Dimensional Portal [BODY 06, Dimension Travel (Travel): 10, Growth: 06, Joined: 10, Limitations: the Dimensional Portal consists of plant-based biotechnology and can thus be affected by Powers that affect plants, Dimension Travel requires 8 APs of time to activate during which time the character is caught in the portal and can be affected by actions from either dimension, Joined is Always On.
The Dimensional Portal is a huge green wall of vegetation with a large gap occupying most of its center. This gap is filled by a swirling, nebulous purple cloud. It is from this cloud that dimensional travellers appear ; they do not emerge from the cloud so much as they “fade in” to our reality. The Portal served as the means by which Geneworm was able to enter the Earth dimension].
