Origin

Moon Squire believed that he had found Ancient Egyptian texts on a hidden message board, which put him in contact with Khonshu. However, this was a false memory implanted by Hydra, which had trained and experimented on Squire to turn her into a beloved superhero (resembling a sidekick of Moon Knight) and represent a Hydra new world order. As a member of The Assembly, she would have a run in with Spider-Woman, who helped reveal the truth to her and her teammates.

New Champions

After he was saved from Hydra, he was returned to his family and assembled with his former Assembly teammates as the "New Champions." When Hellrune got in over her head looking for her long lost family, she casted a spell to teleport her team to her location, however, the spell teleported additional teen heroes who also look like sidekicks but aren't.

While everyone else was fighting, Hellrune was drawn away by a voice belonging to her sorceress aunt. She was freed form her prison by Hellrune and then helped Runie tap into her magic potential ending the viking zombie horde. In the aftermath, Liberty extends membership to all the teens that were teleported there, but only a few accepted communicators for future meet ups, including Hellrune who thought she needed to stay with her newfound relative.
