Similar to many other supernatural creatures, ōkami look like normal humans. However, like werewolves, they grow canine-like teeth. In addition, they feed on human victims but, unlike the other species, each ōkami have a favorite type of prey. The one seen in the episode prefer to eat lone women, as specified by Rufus.
- Superhuman strength - Ōkami are strong enough to casually overpower normal humans and dig themselves out of the ground.
- Superhuman Agility - Ōkami are faster and more agile than normal humans, to the point where one was able to silently cling to ceiling rafters to hide.
- Superhuman Durability - Ōkami to survive a shotgun blast, but are not invulnerable. It takes having to be stabbed seven times with a special dagger to kill them.

- Fangs - Ōkami have razor sharp fangs, which they use to devour their prey.
- Bamboo dagger blessed by a Shintō priest - It is been shown that there is a method to effectively kill ōkami, which consists of stabbing them seven times with this weapon.
- Dismemberment - Bobby Singer made use of a woodchipper by shoving the ōkami into it to kill it. This also proved effective.
Ōkami (狼) is a Japanese word that means "wolf". However, in the same language, there is a word with the same pronunciation - Ōkami (大神, literally "great deity"), which is also a reverential title of some Japanese Shintō deities and, historically, the Emperor of Japan.
- According to Bobby Singer's Guide to Hunting, the Ōkami is a cousin to the Werewolf, but specific to Japan. Their characteristics and abilities are pretty much similar to their cousins, even up to their diet of human hearts.
- In the same book, Bobby also revealed that his first true intentional hunt involved an Ōkami.
