Space Marines are genetically enhanced superhuman warriors, created to
serve the God-Emperor of Mankind. They are considered among the most elite and powerful soldiers in the
galaxy, tasked with defending the Imperium of Man against countless threats, including alien races, heretics, and demonic entities from the
Warp.
Space Gweems are the
dopey cousins of Space Marines created from the leftover parts after they are created. Pysically, they are similar to Space Marines except that their cranium is filled in completely with solid muscle. Space Gweems have a fierce distinct battlecry; however, it is entoned at a frequency undetectable by
humans, Space Marines, and Space Gweems. Strangely, only crustaceans can detect it.
