1. Since he doesn't have legs, Gub floats an inch above the ground. 2. His head and arms are detached from his body but he can't take his head off or anything like that. 3. I'm making all of this up as I go lol. 4. He is still a human, this is just what humans look like in the Gubiverse. 5. I'm not gonna expand on the "Gubiverse" this isn't some multiverse thing it's just the world he lives in. 6. RASM isn't in the Gubiverse, Gub in RASM represents me and my scratch account. 7. Gub is short for Gubudubuggy (no last name) 8. His name originates from a keyboard spam. (It was originally closer to gububugy, but I don't remember exactly.) 9. The RASM version of Gub may be expanded on, though that would be more of an expansion on the RASM universe rather than Gub. 10. His clothes are part of his body and he has no reproductive organs, so don't even THINK about drawing *special* art. 11. He is an immortal ageless being whose power transcends this universe. 12. That last one was a joke, he's just a normal guy 13. Or is he? 14. Yeah, he is. 15. I'm out of ideas.
Big thanks to @Nitemanuim for the Gub redesign.
