I originally made this character years ago on a generator I found somewhere on DeviantArt, which I unfortunately can’t find anymore.
Despite his human appearance, Novocaine is actually an alien in disguise. The young alien hero arrived on Earth just as the then teenage human hero Adrenaline was starting out his career. Novocaine befriended the young hero and recruited him to help him track down a criminal from his planet.
After his mission was complete, Novocaine thanked his new friend for his help and left Earth to return home. Years later, Novocaine has returned to Earth with a new mission and once again seeks out his old friend but his mission is a little less cut and dry than tracking down a criminal this time and Adrenaline now finds himself in a complicated position where he has to decide whether helping his old friend is worth potentially putting his entire planet in jeopardy.
