Original PET

The first two Battle Network games used a model simply called “PET”. This PET was used to combat the WWW and Gospel crime organizations.

Description
Much like the Advanced PET this model flips open, with a screen on the left side and a keyboard on the right. A camera can be found in the middle next to the screen, most likely so the Navi can see the operator. Battle chips can be sent with a slot on the right side of the keyboard. Along the bottom is a battery which doubles as a handle which folds up for easy storage. A retractable cord lets the user Jack-In. This PET has only been seen in one color.

In the games
The first two games are the only time this PET was seen. In MegaMan Battle Network 2, Lan receives a wireless adaptor from Mayl before he leaves for Netopia. The adaptor is believed to come in two pieces, one to connect to the PET, and the other to connect to the desired jack-in port. Helpful as it is its also difficult to use, as the user must throw the device into the port. This is the first intense of wirelessly Jacking-In, a feature which would become standard later on.

In the Anime
This PET did not appear in the anime, but can be found in early concept art.

In the Manga
Lan uses this PET in volumes one through four of the NT Warrior manga. It is smashed on page 57, when Airman and Arashi attack Lan and Chaud. Lan then attempts to change the battery in an attempt to save MegaMan. As a result of this incident Lan gets to try the newest model. In a flashback of Lan introducing MegaMan to his class he mentions that it is the latest model implying there were others before it.
