Looking at this, I'm more inclined to think of a fox than a wolverine. I'm not sure why a fox instead of a wolf, but it definitely doesn't say wolverine.

Wolverines are members of the weasel family, they're not like wolves. Using a wolf base to represent a wolverine character isn't the best idea; wolverines' muzzles are shorter than wolves', their ears are a completely different shape. Their bodies are a different shape, their skulls are not at all similar. Heck, even their leg joints aren't the same; wolves' back legs are digitigrade, they walk on the tips of their toes. Wolverines are plantigrade, they walk on the full foot like humans and bears do.
