Revenant

Harvey Lewinski is a major protagonist in The World of Heroes storyline. He is a socially awkward geek with ghostlike powers and a desire to make the world a better place. He was one of the top students at the ZPA, in combat at least. He has a mixed Jewish-African American background.

History
Harvey grew up in of New York City, though according to him he was born in a Jersey City hospital. He was a delinquent and one day went over his head by unknowingly delivering goods for a crime boss. He managed to turn himself at the ZPA, where he also met the love of his life.

Story
Harvey was a leading member of The Watchdogs, though he was also the one who turned to the authorities when things got serious. In spite of this, both he and his partner Darcy did most of the investigative work that eventually culminated in the end of The Doom Disciples. The duo have quite a few stories to tell, but none compare to The Bush Incident. Maybe one day, Harvey will tell it to you. Despite the both of them being 270 miles apart, they both had a feeling their paths would intersect once more. After all, you can't separate a Hero for too long.

He was also one of the two subjects taken by The Doom Disciples to try to force a second awakening. Unlike with Kiara, the procedure was successful on Harvey and improved his powers twofold... The catch being the trauma associated with it scarring him for the rest of his life.

Costume
Revenant's costume wasn't very elaborate. Normal clothing with a custom made mask that resembles an old goalie mask. His mask, dubbed "The Phantom Thrasher" had three "modes": Night, Thermal and Telescopic which allowed Revenant to snoop around easier.

Power
Harvey's powers are a very interesting case: two very different powers living inside the same Parahuman. Probably, Revenant is a new class of Parahuman all on his own. His powers allow him to become invisible and/or intangible at will, as well as fire green plasma from his fingertips, similar to Vigil's Vermilion Flames. In fact, he was even mentored by Vigil during his apprenticeships.
