A reference sheet for a character I discussed with friends this week, meet Tiss the robotic sergal!

With a modular chassis that can be adjusted to a multitude of body types, ability to consume regular food for fuel, soft-touch shell and autonomous sentient AI her model is suited to living and working together with organics, and interacting with them naturally, while preserving the artificial frame's durability and strength.
"Muscle" color depends on the heat carrier fluid used, and can be changed by draining and swapping it out. Multiple body types and attachable parts can be added and replaced on the fly - but most robots of her model stick to a favored configuration.

Tiss and prefers to stick to a universal body variant, convertible to both a taur form for extreme mobility, and a nimbler bipedal for constrained spaces - while not as efficient as a singular variant, it's more versatile.

As usual, I love comments and critique!
