This is in the Animated TV Series category, but the question seems to pertain to the Megaman Battlenetwork 3 White game for Gameboy Advanced. I will answer the part about the game, being unsure about the TV series. MMBN 3 White ends with the deletion of Alpha by Megaman, and Megaman's subsequent self-deletion to save Lan's life. For a couple of months, the WWW is rounded up to await trial, and Dr. Cossak recuperates in a hospital while Lan struggles to adapt to life without Megaman. The day before he begins the sixth grade, his father decodes an electronic message left by his grandfather's avatar with Lan upon Alpha's deletion. He then installs Lan's new NetNavi while Lan is asleep. Lan is then woken up the next morning by Megaman. That's the ending to the main story. Plotwise, the FINAL ending is with Bass's resurrection in Secret Area 3 as BassGS, or Gospel Soul. Upon deletion, Megaman is rendered the most powerful Navi in the Net, and . . . they decide to go home.
