Beings from the fifth dimension have science so advance, we take it for magic! This make the beings not bound by any third dimensional rules / laws, making them essentially omnipotent. Bat-Mite and Mr. Mxyzptlk are two of them. Here some info about hem:
- Bat-Mite: Bat-Mite is Batman's biggest fan and sometimes his biggest headache. He appears in our 3D views as a small child or elf in a Batman costume. He loves to see Batman in action usually causing him to make strange events to see his hero in action. However, he will leave Batman alone, when he figures out he angered his idol.
- Mister Mxyzptlk: He appears like a small old man. He came to Metropolis to pulls pranks and take over the world! But settled on tormenting Superman. His only weaknesses are he is gullible and if he says Kltzyxm (his name backwards), he sent back to the fifth dimension for 90 days. He is usually presented as a magic-like trickster. He is name is pronounced "mix-yez-pittle-ik" .
Despite their differences sometimes they teamed up to tormenting Batman and Superman.
