10 Bizarre Cameos In X-Men Comics

By the late '60s, early Marvel creators must've been running out of ideas, because in 1967, the X-Men #40 "borrowed" the concept of Frankenstein's Monster. To their credit, Marvel writers did put their own spin on it, going to great lengths to explain how Mary Shelley's book was actually non-fiction and Frankenstein's Monster was in fact a high-tech android with a possible mutant creator.

The X-Men ultimately defeat the monster and, in a big reveal, Professor X tells the team that Frankenstein's Monster was actually an android built by aliens. It was sent to Earth long ago to act as a liaison to humanity, only it malfunctioned and was condemned to be frozen in ice. When it was thawed, it misidentified the X-Men's bright costumes as those of its creators. It would almost be tragic if the plot wasn't so bonkers.

By the end of this fever dream, readers are left with a couple questions. Why did the alien race send a such a monstrous ambassador? Why did it look exactly like the Universal Pictures's version of Frankenstein's Monster? Why couldn't Professor X have figured this out before sending teenagers into battle? Who can really say? That's just Silver Age comics for you.

And to add further confusion to it all, the actual Frankenstein's Monster has appeared in several Marvel comics since, but this version of the character is a one-off never to appear again.
