Meeting Ruby's Group in Mantle

Pietro is described by Maria as "one of Atlas' finest minds" that works with the Kingdom of Atlas on its technological projects, having been the one to build her prosthetic eyes and adjusting them every decade.

Upon arriving in Mantle, Maria Calavera took Ruby's Group to Pietro's Pharmacy and introduced everyone. There, he explained his business in the city; aiding the citizens by providing them prosthesis. Pietro informed them he had heard of the team through his daughter, Penny. After the Creatures of Grimm attacked the city, Pietro and Maria watched as Ace Operatives captured the Huntsmen.

After Ironwood and Ruby's group came to a mutual understanding over each other's actions, Pietro was tasked with upgrading Team RWBY's and Team JNPR's weapons and armor, fitting each new addition to the individual's needs. He also repaired Yang Xiao Long's broken prosthetic, providing a new model.

After Tyrian Callows frames of Penny during a massacre at Robyn Hill's election party, Pietro's daughter returns to his laboratory for comfort. Ruby Rose talks with Pietro about Penny's recovery from the trauma of the party. Pietro states that the footage of Penny was taken from previous incidents of her around Mantle. Pietro says that whoever was responsible for the fall of Beacon would be able to break into Mantle, but that Atlas has been upgraded. Weiss Schnee asks who might be able to break into Atlas, to which Pietro replies that it would include systems Weiss points out would be controlled by the Schnee Dust Company. Pietro expresses his concern about Penny; Ruby states that if she's dismantled, she can be reactivated. Pietro however reveals that Penny's Aura is in fact part of his. He even states if the people of Mantle get their wish to have Penny destroyed, he won't be able to bring her back with his current remaining Aura. Ruby reassures and promises Pietro that they will find the culprit.
