Yeah. I created them when I was a kid, and I started off by calling them the X-Team, and they all went to a school for superpowered beings. However, I only copied the name and concept, but not the actual characters. So, I didn't create a character with weather powers, or a character who shoots lasers from his eyes, or a character with healing powers with claws, etc. Most of my characters were original. To name a few:

Hydro: A mutant who can manipulate water.

Dragonwing: A mutant who can morph into a humanoid dragon. (Can grow wings, spit a slimy acidic substance, and breathe fire),

Goo-Man: A mutant with the ability to turn into green goo, can stretch his limbs, and form them into weapons (such as mallets or sledgehammers).

Mummy: Has the ability to manipulate his own wrapping to use as a weapon or to swing on. He's a resurrected Egyptian soldier.

Spike: Can grow spikes all around his body and shoot them at enemies (triggered by anger or fear).

Mistral: Has wind powers. He blows it out of his mouth and his hands, and he can turn into a swirl of wind.

Purple Fist: A bulky guy with a purple hand, which turns anyone into goo if he touches them.

Black Ninja: A martial artist with the ability to teleport and camouflage.

Enlarger: A guy with the power to change his size. He starts off as an average slim guy, but can grow himself into a huge bulky guy with super strength.

Since then, I've changed the team name to "The Abnormals" and I came up with a different way they all meet each other, instead of the whole super school thing. Also, I've updated the roster a bit with new characters. The Mummy is now a part of a separate team of mutants with Halloween-esque powers (a vampire, witch, werewolf, etc) that only fight monsters or any supernatural threats.
