Try to justify your choices.

Pic related, for Superman. Think about it. Superman is the possible alien that could come down to Earth. Xenomorphs are everything that Kal-El isn't. It makes perfect sense. Plus there would be a lot of perfect conflict there since Superman cherishes all life. How would you defeat a Xenomorph hive without killing any of them?
