Powers and Abilities
In Realm of Death, his mother, Sandra, is kidnapped by Fistrick and his gang. When Ben gets there with Tetrax and Sevenseven, he finds out Fistrick has a pistol to her head. However, it turns out to be a Null Void projector. Fistrick shoots out a portal and Ben is nudged into the portal by Captain Nemesis' laser blast. When he gets there, he is saved from falling to his death by a Plumber named Magnus Declan. Magnus leads him to a tent, his home, and they begin talking. Later on, they are attacked by Null Void creatures. After a long battle, Magnus' tent is destroyed, leaving them without a home. Magnus intends to go off on his own, but Ben convinces him to take him with him, making them partners.
