1. Wolverine is only 5’ 3”. He’s as tall as Mila Kunis.
Hugh Jackman is 6’ 2”. They used tricky camera angles to make him look shorter.
2. Wolverine’s senses are so well honed, he can identify shape shifters and sense when people are lying.
It’s even been suggested that his sense of smell is so strong, he can smell light waves.
3. Wolverine is probably a liberal.
At the very least, he doesn’t seem to be a huge fan of George W. Bush.
4. Wolverine’s origin story has changed several times. There are rumors that he was originally going to be an actual wolverine that mutated into a human.
It’s not clear how this rumor got started. Wolverine’s creator, Len Wein, denies that he ever stated this as the original origin, but the idea that Wolverine was an actual wolverine is so persistent that it even came up in the DVD extras for X-Men Origins: Wolverine.
And then, at some point, Sabretooth was originally supposed to be Wolverine’s father.
When Chris Claremont created Sabertooth (originally as a villain in the Iron Fist books) he intended Wolverine’s long-time rival to be his father. This potential origin was later scrapped, and eventually S.H.I.E.L.D. conducted genetics tests to confirm that Wolverine and Sabertooth were not related.
5. Wolverine has a son named Daken and a “daughter” who is actually a female clone of himself named X-23.
Daken is the child of Wolverine and his deceased wife Itsu, and serves as Dark Wolverine on the Dark Avengers. X-23 is a female, two-clawed version of Wolverine who started as a villain, but is currently working with the Avengers via the Avengers Academy.
(Some claim that Daken is a gay character, but writer Marjorie Liu claims that it’s more likely that Daken just uses sexuality to manipulate others.)
6. Wolverine is old. Like, 130 years old old.
According to his most recent origin story, Wolverine was born as James Howlett sometime in 1880s. He fought in both World War One and World War Two. He even worked as a covert agent for the CIA during the Cold War.
(There’s even a scene in X-Men Origins: Wolverine where Wolverine can be seen fighting in the American Civil War, but that’s probably not canon since James Howlett is Canadian, and the Civil War ended two decades before he was born.)
He can speak English, Japanese, Russian, Chinese, Cheyenne, Spanish, Arabic, and Lakota fluently. He also knows a bit of French, Filipino, Thai, Vietnamese, German, Italian, Portuguese, Korean, Hindi, and Persian.
8. He’s also used that time to become an expert in virtually every form of martial arts.
Despite that, he fought Spock once and lost. Yes… Spock. From Star Trek.
He also lost to Squirrel Girl once.
9. Despite constantly being described as a loner, Wolverine has been on more teams that any other character in the Marvel universe.
According to Comic Vine, Wolverine has appeared on 35 different teams.
10. Despite being regularly depicted as a heavy drinker, Wolverine’s healing factor makes him much less susceptible to the effects of drugs and alcohol.
11. The lore behind Wolverine’s secondary power, his signature claws, is all over the place.
When Wolverine was first created, his claws were just part of his gloves. Later on, they changed it so that the claws were surgically inserted by the Weapon X program. Then at some point, Magneto used his power to rip the adamantium out of Wolverine’s body, revealing that Wolverine had bone claws all along.
12. The name of the fictional metal grafted to Wolverine’s skeleton, “adamantium,” is derived from the Greek word “adamastos”, meaning “untameable”.
Adamant (and it’s variations, adamantine and adamantium) makes appearances in Greek Mythology, the works of Shakespeake, and even in The Lord of the Rings. In myth, the metal was ‘a legendary stone said to be impenetrable, often identified with the diamond or loadstone.’
The scientist who accidentally created adamantium did so while trying to repeat the process of creating vibranium, which is the (fictional) metal that Captain America’s shield is made of.
13. Wolverine is virtually indestructible. He’s bounced back from being run over by a steamroller…
…from been ripped in half by the Hulk and left for dead for over 3 years…
14. He’s not totally invulnerable though.
Professor Xavier states in the Xavier Protocols that the only way to stop Wolverine is to decapitate him and remove the head from the vicinity of his body.
There are also certain materials that suppress Wolverine’s healing factor, such as carbonadium and a katana of mystic origin called the Muramasa blade.
15. At some point, Bob Hoskins, Russel Crowe, and Dougray Scott were all considered to play Wolverine in X-Men films.
And before Brian Singer came along to direct the first X-men movie in 2000, Kathryn Bigelow was attached to direct an X-Men film.
