GB! Ink, when he's a few days away from transforming, gets really kinky/dirty-minded... Error still struggles to figure out what exactly causes this, and Ink has the worst memory in the multiverse, so... he isn't much help.

Sometimes, GB! Error will cough up balls of strings, very much like a cat with hair balls. (that's gross, and I'm sorry, but I needed to share—)

Static (Sniper! Error) has really poor eyesight, but refuses to wear his glasses (cuz who does that in the military, lets be honest here), so instead of shooting his targets in the head (like Sharpie or Neon do), he just shoots them in the chest. It's a wider space, and there's more room for mistakes to be made and still get a fatal shot.

Disease GB! Ink gets really irritable when he's lectured about his 'condition', and gets really snarky when people try to tell him not to do things related to passing on the disease.

When GB! Fresh transforms, his 'fresh' filter stops working, and he always ends up cursing like a f*cking sailor.

Werewolf! Ink has a habit of getting on top of tables and howling for no reason at all. He has terrible impulse control. He's basically a giant puppy, what did you expect?!

Vamp! Error has to feed every once in awhile to keep himself alive, so that means that he oftentimes will take one of Ink's pet guinea pigs as a sacrifice... Ink is none too happy about this.

GB! Ink still does art in his blaster form, but it is much more abstract than normal. He uses Broomy exclusively to draw in his GB form.

GB! Ink loves sweet things. Cakes, doughnuts, cookies, ice cream, soda... and also, mint tea...?

Disease GB! Ink's tattoo markings give off a faint red glow when he's in his blaster form.

Ok, I think that's enough headcanons for now—
