So you'd assume he can speak right?

Well he can't. Hes legally mute.

I'd imagine if the trio decided to adopt a child it'd be Chid. Legally adorable but chaotic as hell. (He's chaotic neutral btw)

I'd also say he'd take more of a place like Dimentio, have the chaotic personality of Jevil, or just wanting to control the world to hunger like Marx.

Fuck now I wanna draw them together (Chid and the trio)-

You can also draw him all ya like!
