Progress PET

The Progress PET (also known as the PET III, Progress Personal Exploration Terminal, and Progress PErsonal Terminal.)With MegaMan Battle Network 5, the Megaman Movie: The Program of Light and Darkness, and the 51-episodes Stream anime series, the Progress PET was introduced. This PET returns to a design similar to the anime/third game PET with a wider design, and somewhat resembles a traditional GBA, PSP, or flat faced phone. In the anime, this PET features a holographic touch screen, allowing the Operator/NetOp to drag-and-drop Battle Chip data onto their NetNavi with touch alone. This PET also allows for the attachment of various accessory upgrades, specifically for upgrading NetNavis' abilities during battle. Also, in the anime, the PET also enhanced Lan and Chaud's Cross Fusion strength and also giving them a new design during the fusion.
