Answering what was believed to be a distress call, actually a trap set by the Pro-Registration. Cloak, entering a factory with the other Anti-Registration Members, was shot on Iron Man's order and was protected by Dagger throughout the rest of the mission.
Tyrone Johnson was born in Boston, Massachusetts to Ortis and Adina Johnson on June, 2th 1993. He also has an older brother named Billy. Tyrone had a debilitating stutter and ran away from home 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 supermodel mother was too busy with her 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. Afterward, 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 criminal chemist Simon Marshall who is really the demon known as D'sparye in disguise, developing new synthetic heroin to influence the genetic makeup of anyone who uses it, testing it on runaway teens with fatal results.
Johnson and Bowen somehow survive the injections of the drug, and they flee. During their escape, the drug turns them into superpowered beings giving him the ability to teleport. Tyrone finds himself engulfed in darkness and seized by a strange hunger that eases in the presence of Tandy glowing with a brilliant light. He and Tandy seek help from Dr. Strange who gives Tyrone a cloak to hide his newly shadowy appearance. The two teens dub themselves "Cloak & Dagger", declaring war on drug crime and helping runaway children and teens.
Marvel: Ultimate Alliance 2: Story
Cloak, as well as Dagger, joined Captain America's pro-registration side during the Superhuman Civil War. He used his teleporting ability to transport the Secret Avengers to and from destinations, serving as an easy one-man extraction unit. He teleported the White Star and Secret Avenger forces to the Geffen-Meyer Power Plant where he was shot by a S.H.I.E.L.D. sniper. His injured body was protected by Dagger and White Star units, and he eventually escaped the battle with the rest of the Anti-Registration movement. He would later aid in the attack on the Negative Zone Prison and escaped it. It is unknown whether or not he was taken into the Fold, but it is likely.
