Ms. Madd is the NetOp of ColorMan.EXE and a member of the WWW.

MegaMan Battle Network Edit

She is a member of the WWW and uses ColorMan.EXE to cause a bus to explode with Mayl and Kai on it. However, MegaMan.EXE defeats her.

MegaMan NT Warrior Edit

Ms. Madd is still a member of the WWW and uses ColorMan.EXE to cause a traffic jam. However Yai desperately needed to use the restroom and was stuck. Lan and MegaMan.EXE defeat her and Yai gets to go to the bathroom. She also partcipates in the N1 Grand Prix with Mr. Match, Count Zap, and Yahoot but is defeated early by Mayl and Roll.EXE but re-enters by rigging the lottery to determine two returning competiters. She fights with Mr. Match against Lan and Mayl in a tag match. Their in-fighting causes them to start out losing but get the upper hand when a rigged battlechip causes Roll.EXE to turn on MegaMan.EXE. Luckily they manage to revers the effects of the battleChip and defeat Ms. Madd and Mr. Match. After the WWW is disbanded when Lord Wily goes missing, they start a curry shop to make a living.
