Punisher (Trevor Castle) is the Amalgam of Marvel Comics' Punisher (Frank Castle) and DC Comics' Steve Trevor.
History[]
Former captain in the United States Marine Corps in 1972, Trevor Castle served for five years in the Vietnam War. For his heroism, Castle was twice decorated with the Bronze Star and the Silver Star and four times with the Purple Heart.
When his wife and children were killed by the Mafia, Castle declared a war on crime and became the ruthless vigilante known only as the Punisher. At one point, he was almost killed by a criminal and laid dying in the streets from wounds. Luckily, Punisher was found and nursed back to health by Diana Prince.
Falling in love, the pair became a crime-fighting duo and eventually got married, having a son named Ryan Castiglione together. Though the couple split up, they were eventually reunited as a result of their son's kidnapping by the minions of Thanoseid.
