    The son of Captain Boomerang and Meloni Thawne, Owen was born in the 30th century. At some point in his early childhood, and by some unknown means, he was returned to the present, where he was brought up by an adoptive mother. When he was a young man, rumours began to circulate that he was Boomerang's son with Golden Glider. Boomerang contacted him and apologized for abandoning him. The pair bonded for some time, and Boomerang began to train him in the use of his namesake. When his father was killed in a botched assassination of Jack Drake, Owen took up the mantle of Captain Boomerang.


    Owen Mercer was created by Brad Meltzer and Rags Morales. He made his first appearance in Identity Crisis #2.
