Slime coated, I can leave electric wake. Nature's mistake, not a snake for Pete's sake!

I have jaws but cannot bite, I grip and twist with all my might, What am I?

What redundancy? My name? Sure, they’re technically the same. First: Green, purple, red or white. Last: Cornucopias looming fame Together I’m still my last name though, and my first is also. If you dried me out like my first, the raise in would be colossal.

I'm the silver curve that takes a swoop. You might do this when feeling cuddly. I'm the only one welcome in a liquid group, Because who gives a fork? I don't.

Not present, nor one who repents. I coil my words with dark accents, Can you guess my intents?
