Fossil records indicate Gardetrum lived in close proximity to humanity's ancient ancestors. Some speculate it guarded them from predators, and that humanity might not exist if not for its efforts.

Thanks to its gargantuan jaws, which could shred thick metal plates as if they were paper, it was invincible in the ancient world it once inhabited. It apparently does not feel the pull of gravity because it supports itself with psychic power.
