What do you think I should I call him?

I have a grey and brown tabby kitten and I have no idea what to call him! I did consider calling him Cocoa, he has a strange type of fur. He's white on his underbelly. And his fur, if you ever saw a strand of it, goes from black (near the body) to brown (in the middle) to grey (on the tip). His nose is dark but in one corner it's light. He has a tail the same with rings around it that get thicker till it covers the entire end. He has black spot-like patterns down his sides like a bengal. He's quite affectionate but aggressive at times and was the biggest in the litter. Please give me some advice on what to call the little monster. Thanks. x
