What is batman aliens?

As an AI language model, I do not have personal opinions on topics or beliefs. However, I can provide you with information about Batman and his encounters with extraterrestrial beings.

Batman, being a mortal and highly skilled human, is often portrayed as having to rely on his intelligence, cunning, and combat skills to save Gotham City and ultimately the world. However, he has also faced extraterrestrial challenges throughout his comic book career.

One of his most memorable encounters with aliens occurred in the storyline "Batman/Aliens," where he battled xenomorphs, the iconic creatures from the "Alien" movie franchise. In this story, Batman traveled to the jungle to investigate a missing scientist and came across the horrific creatures.

Another example of Batman's alien encounters can be found in the story "Batman/Superman: World's Finest." In this storyline, Batman and Superman work together to stop an alien invasion led by the villainous Mongul.

Overall, Batman's alien adventures make for thrilling sci-fi crossovers that add an extra layer of excitement to the already action-packed adventures of the Dark Knight.
