Wonder Woman: Why are you Superman’s younger brother? Eric replied: On the first day of travel, I, who was also a baby, climbed into Superman’s baby capsule, pushed him out, occupied the nest by myself, and became a “son of Krypton”.

Superman: Why don’t you save the plane? Eric replied: I will not lift things by stepping on the air.

Batman: Why didn’t kryptonite work for you this time? Eric replied: I originally wanted to get along with you as a Kryptonian, but in exchange it was alienation.
