I ended up drawing more of them, it's a good chance to practice anatomy!
Demya and the Hand have a pretty tight bond and have spent several centuries roaming together, so having a third party join them is an odd addition for both. Their dynamic gets a little fucked but it also helps them grow as a pair.

Kleobis is (un)fortunately in for the ride, considering he can't really do much about it. The Hand has a soft spot for him since it was the one to find him first, so it enjoys carrying him around and making sure he's relatively comfortable.

People tend to underestimate Demya and the Hand in a fight because they think the Hand is a tool Demya has to consciously control rather than an actual sentient creature, and often end up assuming that if they knock Demya out, the fight is over. If anything, that'll just turn the Hand into a murderous killing machine. Ain't that too bad.
Amongst other traits, the Hand can also shapeshift (in a minor way), change size and twist around at its convenience, not being hindered by pesky things like bones or muscles. It's just a demon parasite Hand, it does what it wants!

(the hand and kleobis belong to my friend Destroy, but they don't have an account on here)
