Nextwave
Little is known about the Captain's past before he joined H.A.T.E., the organization which assembled Nextwave. One flashback shows that when he was a child, his mother hanged his favorite teddy bear, Special Bear; due to this, he dislikes teddy bears even in adulthood. As with all of the flashbacks shown in the series, the accuracy of this memory is suspect, as Civil War: Battle Damage Report states that members of Nextwave may have had memories altered by the Beyond Corporation. He claims to be "from ☠☠☠☠ Brooklyn".
The Captain gained his powers from "the Heartstar of the space between the galaxies",[20] also referred to as the "Messianic Siddhe-complex", which was bestowed upon him by a pair of small, green, altruistic extraterrestrials named Spa-Fon and Squa-Tront[21] in order to make Brooklyn a better place. As the Captain was incredibly drunk at the time, it is unknown if he remembers this event exactly, as he immediately attacked both aliens, believing them to be gold-bearing leprechauns.
By his own admission, he used to go by Captain ☠☠☠☠, a moniker so offensive that, when he met Captain America, the Avenger beat him severely and left him unconscious in a dumpster with a bar of soap in his mouth. The Captain used a lot of codenames as well, all of them starting with 'Captain', and had to abandon them all because someone else was already using them. In Nextwave #7 he mentions that he had to pay a "marine-looking melon farmer" to even use his current codename.
The Captain continues to use his codename in the Nextwave group while the other members have dropped them; according to Aaron Stack, this is due to an inability to remember his real name. According to the official theme song of the comic, in tone with the satirical quality of the stories, he no longer has a name, with "The Captain" serving both as a moniker and as an impromptu first name.
Similar to the rest of Nextwave, the Captain dresses in civilian clothes—sneakers, camouflage pants, a trenchcoat, and a white T-shirt with a black star which resembles the Heartstar—despite becoming a superhero "for the mask", as he stated in issue #1.
The Captain is extremely cynical, foul-mouthed, and hard-drinking. His age is as yet undetermined, but he has said his mother conceived him while listening to Roxy Music's 1982 album Avalon.
A text box in one issue states that, despite his name, he is not actually the captain of anything.
