Christian McDonald is The Cure

One night while he was getting a bite to eat Christian McDonald discovered a tiny meteorite fragment, he took it home with him and brought it to his bedroom. While he was bored tossing it in the air and catching it, It suddenly stuck to his hand and painfully absorbed into his body, the next thing that happens is a white semi-liquid substance starts seeping from his pores and turns into a costume for him, humorously enough it took on the form of his OC's Carl Brock's "Cure" Costume, he tested out his new abilities and soon mastered them, he went onto the Internet and searched for other areas that have been pelted by meteors and Soon afterwards he was confronted by a mysterious man saying he wants to talk to him about something called "The Reserve Avenger Initiative." He initially denied the invitation but soon found that other people who were exposed to the meteorites have joined, He eventually relented and became the Team Medic using the codename "Cure."
