Part of team ups
David got involved in a battle with all extra Marvel Heroes, until the events of the Secret Invasion, Civil War and others. He retired at first, but he kept getting pulled back in to get involved in saving innocents from danger. He looks at Bill Foster’s grave, and began helping Bill’s nephew Tom Foster. Tom didn’t want his help, and wanted to know if he was on Tony’s side. Mike said he wasn't, and didn’t want any part of the Superhuman Registration Act, knowing what is like to lose someone important.
David became Gigantor out of retirement to keep fighting and save all innocents. His girlfriend wanted to help, but he said it was too dangerous, and he directed her to stay safe at the Avengers Mansion. Sally said that wherever he goes, she goes, and she used her powers to help and fight together, they kissed.
- Gigantor was originally a fan made character named Mike / Michael, inspired by the team called the Reserves, and the Giant Men team - David Scotty, Peter, and various others. After being renamed, he kept his name, as a middle name, now being the mainstream counterpart of David Scotty as well.
