Cloak & Dagger

Real Name(s): Tyrone Johnson and Tandy Bowen

Tyrone and Tandy were runaways upon whom the Maggia tested a designer drug of a new kind of heroin, which gave them powers.  Cloak can manipulate the Darkforce, and Dagger can throw daggers of solid light. 

Neither Cloak and Dagger have appeared in any episodes of the Avengers: Earth's Mightiest Heroes, but Cloak was confirmed as existing in the continuity by an appearance on Nick Fury's bulletin board of people suspected of being Skrull replacements, and as he and Dagger's origins are co-mingled so tightly, Dagger must also exist by inference.
