@Milkman and @Dead Cruiser, character accepted.
I did want to ask though, since Casey's mother was the previous bearer of the mark, was she a superhero? I think it would be interesting if she was, and also went by the name Galaxion, but after giving birth to Casey, Galaxion 'vanished'. When Casey starts being a superhero, people will recognize him as a younger, male version of Galaxion, and will start calling him "Galaxy Boy", until he publicly tells people to stop calling him that. At least, I think it would be interesting since there are a lot of female superheroes who are 'derived' from male superheroes, but not that many who are the other way around. If Mrs. Nakamura was the previous Galaxion, I might say that she was offered a spot in the Dream Corps., whether she accepted or not is up to you, Dead Cruiser. After her powers went away, the appearance of a new Galaxion would really pique the interest of the Dream Corps.
I've finished the first two Dream Corps. members, Justice and Kingfisher, and am still working on the others. Pacifist is partially filled in but not complete yet. In addition to Lorne Industries as offered by @Sep, Kingfisher's company, Crown Heavy Industries is also open for any tech related tie-ins. I actually want @Rin's Zeta to maybe be part of a collaboration project between Crown Heavy Industries and Dr. Coscarelli, with permission of course.
Perhaps even a bit of Lorne in @Rin (But thats more optional) as it is possible he designed a security system without knowing what it was for.
ThunderTech, the company of Thunderbolt anyone can really play with but since Lorne bought the building and Thunderbolt disappeared it's not been in the best condition.
