2. He’s heavy.
That cool unbreakable Adamantium skeleton puts Wolverine around the 300 lb. mark.
3. He was a member of the Fantastic Four.
Wolverine, Ghost Rider, Spider-Man, and the Hulk became the New Fantastic Four for a 3-issue run (FF 347-349) back in 1990. The arc is too complex to explain, but it involved Skrulls, Mole Man, and The Punisher.
4. He fought alongside Captain America in WWII.
Logan, pre-Adamantium and pre-Wolverine, teamed up with Cap to fight ninjas. It’s the first time the two heroes met and they saved the life of a very young Black Widow (UXM 268).
5. He’s met Captain Kirk and Captain Picard.
A 1996 one-shot brings the X-men to Kirk’s Enterprise (where Spock neck pinches Wolverine) and 1998’s Planet X was a novel set in the Next Generation Era (Wolverine hangs out with Worf).
