S3·E47 Why Are You Here?

Charlie is startled to discover Tesla has been sleeping in his apartment. Meanwhile, Dark MegaMan lures Ms. Yuri into a trap to steal her Crest of Duo. When she refuses to comply, Dr. Regal then appears and steals it himself. Lan, Charlie, and Tesla battle with the remaining Darkloids, deleting CosmoMan and forcing Dark MegaMan to retreat. Dr. Wily explains that Dr. Regal needs the data within the Crests of Duo to achieve access to the power within Duo's comet. Dr. Regal has planned such a thing for decades as he had already taken Baryl's Crest twenty years ago when Baryl was alive.
