7. He Was A Wimpy Kid
What X-Men Origins: Wolverine didn't explore was that Wolverine was a sickly child who was the son of rich plantation owners. Suffering from various allergies, the young James Howlett (that's his real name) was a delicate boy whose only friends were a young girl named Rose and the groundskeeper's son, Dog. For years, it was believed that Sabretooth was Dog, but it has since been confirmed that that isn't the case. Regardless, as well as revealing this very different side of the character, the series also insinuated that Wolverine had a brother who had claws too. He apparently died, but could Marvel bring him back? It's yet to happen...
