A Lethal Protector called Marcus Morgan (Invincible x Male Oc)

One day, a fallen meteor crash landed on US soil. But with the meteor came an unwanted guest. A parasitic like creature slithered away from the crash to find a suitable host. And in it the alien found a host in a teenage boy with mental problems and family issues.

How will the boy cope with hosting an alien parasite within his body while also dealing with the problems of keeping it under control while also managing his normal life? How will he deal with the fact his world is now under the threat of constant alien attacks, and even a greater threat that lurks just within the hero agency that was sworn to protect their world.
