Wolverine

Wolverine is a superhero who appears in Never-ending story.

Never-ending story
After Brainiac's defeat by the Red Tornado and the fall of the Spongeternet, Wolverine saved SpongeBob SquarePants from Magneto, who wanted to strangle him with a pipe. He and all other Marvel characters were then sucked into a portal.

However, some popcorn (that was being eaten by Patrick Star, Gary the Snail, Squidward Tentacles, Sandy Cheeks, Eugene Krabs and Plankton) turned into a plot hole, and the Marvel characters came out of it. Uncle Grandpa and Steven Universe fixed the plot hole.
