Here are three more characters that came to mind. Let's see...

Kyokan is the biggest of the bunch and has quite an appetite for himself. He uses the gem on his muzzle to reflect any light that hits it and his tail is stretchy and the tip can stretch quite a bit. However this lug does have a soft spot for jelly or anything that jiggles. Despite his huge size he is kind but he can be klutz when he wanders to a populated area.

Bizel is a curious warslug that loves to go where his tail leads him. He uses the green patches on his tail to smell and his green horns to feel and listen to area surrounding him. He has a different kind of stomach which allows him absorb fluids that he drinks. Even though he does eat live prey his stomach can't digest any meat and the "acids" tickles them. Despite that he does enjoy letting them squirm around until the "acids" coats and encases them in an egg which he spits out.

Shinzui is a spirit dragon and he used to be an ordinary blue dragon until he had an unfortunate run in with a certain hybrid and through sheer will power he let his soul escape but left his body to be churned. Now he says that he haunts him and will never leave him. He is still able to devour live prey but they are only trapped within his spiritual body. He can absorb souls but it takes time and he's only capable of three things if his energy is low. Invisibly, transparency and sneaking into living bodies which gives them a huge chill.
