X-Men crossover "Utopia", in which writer Matt Fraction stated they would be presented with a chance "to have their reputations exonerated and their records sealed [if they join the Dark X-Men]." Fraction explained, "Osborn presents it to them as the ultimate public service, [in which] they can work off their past indiscretions—[such as] Cloak's dealings with the Avengers during the Skrull invasion." Fraction claimed the more appealing part of Dark X-Men was to see how Cloak and Dagger react in a real superhero team scenario. To tie in with the 2015 storyline "Secret Wars", ND Stevenson and Sanford Greene created a spin-off series based on Runaways. Fictional character biography Origin Tyrone "Ty" Johnson (Cloak) and Tandy Bowen (Dagger) meet in New York City as runaways. Tyrone is a 17-year-old boy from Boston, Massachusetts, with a stutter who ran away from his struggling parents to New York City when his speech impediment prevented him from stopping his friend from being shot by the police, who mistakenly believed he had just robbed a store. Tandy is a 16-year-old girl from a privileged upbringing (born in Shaker Heights, Ohio) who ran away because her multi-millionaire mother was too busy with a supermodel career and social life to spend time with her daughter. When they meet, Tyrone considers stealing Tandy's purse, but before he can, a thief steals it and Tyrone retrieves it for her. Afterwards, they have dinner and quickly become friends. When naïve Tandy accepts an offer of shelter from some strange men, wary Tyrone goes along to protect her. The two teens are soon forcibly delivered to Simon Marshall, a criminal chemist who's developing a new synthetic heroin for Silvermane and the Maggia with tests on runaway teens that have fatal results. Johnson and Bowen somehow survive injections of the drug and they flee. During their escape, the drug turns them into super-powered beings. Tyrone finds himself engulfed in darkness and seized by a strange hunger that eases in the presence of Tandy who now glows with a brilliant light. Tyrone tries to hide his shadowy appearance in a makeshift cloak by absorbing Marshall's thugs into his darkness while Tandy strikes them down with daggers of light. The two teens dub themselves "Cloak & Dagger", declaring war on drug crime and helping runaway children. They are aided by local priest Father Delgado and Detective Brigid O'Reilly.
