Cosmo Kid is Terry Space, son of Gregory Space, a normal middle school kid who is also the protector of the universe. His mom Martha Space is human but his dad is Cosmonian.
Terry didn't want to be afraid of these powers and instead wanted to use them for good. So he learned how to harness these powers, and once he did he became Cosmo Kid. Cosmo Kid has to come into contact with the energy of the sun once a day or he will die. Cosmo Kid's archenemy is Dys Dude. Dys Dude has the ability to become the opposite of anything he wants.
When Terry turned 14, he started noticing that he wasn't like the other kids. Sometimes he would float up in the air randomly, but luckily no one would see it. Some of the powers that he possesses are flight, heat ray vision, invisibility, and super strength. Along with other hidden abilities he still has to unlock. People say is a comet flying through space.
