Cloak And Dagger are runaways: two lonely teenagers who ran away to New York City to seek a better life. Fate, however, had other plans for them.
Tandy Bowen grew up in Shaker Heights, Ohio, the daugther of a multimillionaire and his trophy supermodel wife. Her dad abandoned the family while Tandy was very young, and her mother was too busy with her career and social life to pay much attention to the girl. Even her boyfriend forgot about her as soon as he went to college. Feeling empty and alone, Tandy boarded a bus for New York City with dreams of becoming a dancer.
Tyrone Johnson, or Ty, had a very different background. Ty was raised in the slums of South Boston, Massachusetts, and had been born with a speech impediment. When his best friend died because Ty was unable to say the words that might have saved him, the distraught teenager fled Boston.
The two teenagers met up in New York and became fast friends, but were captured and were taken to a lab. Chemist Simon Marsahall, who worked for gang leader Silvermane was developping a synthetic drug, a cheap version of heroin that could easily be smuggled. He began his tests on teenagers with only two survivors. Ty and Tyrone. This experiment led to their extraordinary powers.
The two use their powers together to defeat enemies. Cloak disorients them using his dark dimension and Dagger finishes the job with her daggers of light.
Recently, the duo aided Captain America and the Secret Avengers in Civil War.
