I'm gonna start out with Wictor:
A shadow cat monster with the the ability to turn any parts of his body into cage looking mouths. Sometimes the mouths have teeth, sometimes they don't.
He can eat almost any kind of meat bur prefer live prey, especially anything he can hold a conversation with. He will captures such prey in a mouth cage, for a quick chat before dinner. Unfortunately for him, he's pretty naive and not the sharpest tool in the shed, so his prey often manages to talk their way out of getting eaten.
He's extremely curious and if something pique his interest he will not cease asking questions until his curiosity is satisfied.
When turning a body part into a mouth cage, the skin and flesh of that body part becomes extremely dense (or tough, I'm not exactly sure which word would be the most correct to use here). Dense enough to withstand bites, cuts from sharp weapons, punches and gun shots. Still able to catch on fire though and he's not magic proof.
He's capable of lifting very heavy loads, but sunlight makes him weak and uncomfortable.
He has an intense fascination with anything that gives off any kind of light and will unconditionally love whatever/whoever is giving off said light.
Wictor rarely stands on his hind legs and prefers walking on all fours.
And I think that's all for now!
