Mega Man Battle Network 3

MegaMan Battle Network 3 (Rockman.EXE 3) takes place not long after MegaMan Battle Network 2. There are two versions: White (no subtitle in Japan) and Blue (Black in Japan). A NetNavi tournament called the N1 Grand Prix took place. Half of the game involved qualifying for the tournament. Once Lan and MegaMan get into the competition, the tournament was discovered as a set-up by WWW to intimidate the world about their return.

WWW had already been attacking in between qualification rounds. As with before, Lan and MegaMan had to defeat the WWW net navis. However, the net operators always managed to escape with special programs known as TetraCodes. The codes were required for WWW's plan to revive the net beast Alpha (Proto in Japan).

Alpha was the orignal prototype of the internet. However, he went beserk and devoured any navis and programs. The scientists were forced to seal Alpha to prevent further damage.

In addition to the TetraCodes, WWW had needed Bass in order to awaken Alpha. It was revealed that Dr. Wily, head of WWW, was moving behind-the-scenes in net mafia Gospel, and had put them to the task of creating a copy Bass specifically for the resurrection. This time, Wily didn't need a fake Bass because he tricked the true Bass into removing the final security measure. When Lan and MegaMan arrived, they fought and destroyed Alpha. In its last moments, Alpha absorbed MegaMan, and the navi was thought to have been deleted. However, a letter Lan's grand-father left them contained coding that let MegaMan be restored.
