Cloak (Marvel) Wiki

Tyrone "Ty" Johnson, known alongside his partner as "Cloak & Dagger", is a superhero appearing in Marvel comic books. They debuted as a duo in Peter Parker, the Spectacular Spider-Man #64, published in 1982.

A teenage boy with struggling parents, he struggles with a speech impediment, which prevented him from saving a friend that was unjustly shot by police, assuming he had robbed a store. Tyrone ran from home in distress.

He considered stealing Tandy's purse to get by, but instead prevented a thief from doing it. He and Tandy quickly become friends. Shortly thereafter, they're abducted by the Maggia and used as guinea pigs for designer drugs. Tandy, Tyrone, and a Chinese immigrant (later retconned to be Mr. Negative) were the sole survivors. The pair eventually escapes and discovers that the drugs have granted them powers.

Cloak can teleport and turn intangible through the darkforce. Dagger can create daggers and heal through the lightforce. They draw power from one another, further strengthening their newfound bond.
