MegaMan NT Warrior - Season 3 Episode 46 Pursued Crest

The CrossFusion Members formulate a plan to infiltrate Neo WWW's hideout and rescue Tesla. Also, the member's Crests of Duo have mysteriously faded away, the first three victims being Chaud, Raika, and Princes Pride. Count Zap also assists Mr. Gauss in the rescue of his niece. To pass security, the members must scan their hands. But once inside, the Darkloids Cloudman and LarkMan attack. Battling up to the top, they reach Dark MegaMan, who reveals that Mr. Gauss tricked the members into the tower in exchange for Tesla. The hand scans gave Dark MegaMan the data that rested within Duo's Crests. As the members escape the tower, Tesla CrossFuses and vanishes.
