It was even strong enough to be able to threaten Kitsunoh with a 2HKO from Brave Bird.
So yeah, Close Combat has nothing to do with fists/arms. (The Natural/Breed list now even includes Growlithe. Snubbull, Teddiurda, and Zangoose [Level-up] could all get it before)
I wouldn't worry about flavor when it comes to movepools. Most of the movepools that tend to win combine good competitive and flavor elements. Or at least, I always try to balance those in my submissions. I thought Tomohawk's movepool went a bit overboard, but I'm a harsh critic of those things.
