C.Q. Cumber (specifically this one, as there are a lot of them around the Deepsea Metro) is an entity that works for Commander Tartar. While his gender is unknown, he prefers he/they/it pronouns.
If you even slightly screw up a test, he WILL splat (kill) you. Dropped the 8-ball? Congrats, you're going to get splatted by a ticked-off, humanoid sea cucumber.
C. Q. has the ability to grow around 8 legs out of his back and take a position similar to that of a spider. If he does this, you should run.
