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.

Magnetrix, a fellow former Hydra cadet who did not get the invite, decides to mess with the team. They set up a meeting with Ms. Marvel and her Champions roster, jailbreaking Psycho-Man to give them an angsty push. Liberty and Ms. Marvel accidentally find Magnetrix while they fought. Magnetrix's panicked and used her powers on the two before escaping, causing their heads to clear from Psycho-Man's powers. They were now able to take on Psycho-Man freeing everyone else from their rage-filled mind-control. The two teams parted ways with the old Champions giving the new team their blessing.
