Progress PET

The Progress PET, also known as the PET III, and PErsonal Terminal, featured in MegaMan Battle Network 5, the Megaman Movie, (Rockman: The Program of Light and Darkness) and the 51-episode 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, if the Operator pressed their navi's symbol, the PET would project 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. It's Predecessor is the Advance PET and Advance PET II (Megaman Axess). It's Successor is the Link PET EX (Megaman Beast) and the Link PET EX DX (Megaman Beast+).
