Barb and Juniper, who are upset with each other, each steal a Krei battery so that they can each look for the orb that powers them. Meanwhile, Mole gets on Fred's nerves when he steals his idea for a superhero museum and carries a fake signed photo from "Lizard Guy", resulting in Fred revealing that he is Fredzilla and part of Big Hero 6. Unconcerned with their safety, Mole blackmails them with personal favors until he decides to become a member as well with a small red variant of Fred's suit. Barb and Juniper discover that the orb was taken out of the police archive and is in Mole's possession and head to his comic book store where they make up. Fred and Go Go defeat them with the former rescuing a semi-grateful Mole. When he tries taking the orb, he gets electrified and forgets the identities of Big Hero 6.
