3x5 - MegaMan NT Warrior

While investigating a NetSaver case, Lan notices helicopter pilot Charlie Airstar at the scene of the crimes. Lan presumes Charlie is the culprit, but Charlie is really tracking the true criminal on his own: director of DNN network, Sunayama (and even has the nerve of pursuing Sunayama to Lan's school). Sunayama uses Asteroid DesertMan to fight back, but MegaMan and ProtoMan team up with Charlie's GyroMan to stop him.
