Progress PET

The Progress PET was introduced in Mega Man Battle Network 5 and the third episode of Stream. It is the forth design of the PET, not counting the Advanced PET 2, and was used to combat Nebula and Duo.

Description
The Progress PET's design differs vastly from that of its predecessor. Rather than being held vertically it demands to be held horizontally, much like a traditional GBA or PSP. Like the Advanced PET it can be customized in a wide variety of colors. Along to top and bottom are slots called custom gates which can be used to install accessory upgrades. These upgrades can do anything from improving the abilities of your navi to providing a better grip for the operator. On the right side of the device is a retractable cover which conceals a jack-in port and a slot for Battle Chips. Touching the navi mark to the left of this will bring up a holographic touch screen which will allow the user to drag-and-drop battle chips to their navi. In the center of the PET is a screen and to the left are two buttons, a directional pad and an LED. Battle Chips also differ in design than other generations.

In the Games
Lan gets this PET sometime before ''Battle Network 5. ''The few mentions of it in game most are just E-mails and message board posts discussing how to use it. Lan’s friends PET's are stolen by Nebula early in the game. When they are taking a vacation on Oran Isle Dex mentions that he is using a SubPET. While trying to solve a theft on a cruise ship, Colonel or Protoman(depending on the version) mentions that navis jack-in using inferred rays. Before facing the final boss Lan gets an opportunity to take back the stolen PETs. Gate Devices can again be used in as a Japanese exclusive.
