Talpha, an old enemy of Magnus, destroys buildings in North Am and threatens to keep doing so until Magnus is delivered to him. But when Magnus is found, he has just returned from the Unity sage and is no condition to fight. So Leeja has to come up with a plan in “Trouble Below.”
Bent on the destruction of Magnus, Talpa wreaks havoc upon North Am! But the Robot Fighter is in no shape to face Talpa, having just returned from the Unity Conflict. In response to Talpa's demands that Magnus be turned over to him, Leeja tells the robot to return to San Gabriel. Now recuperated, Magnus fights Talpa, alternately exposing the robot to extreme heat and cold, making it brittle enough to smash!
