The last two battles are with Lucemon, the evil digimon from season 4 of Digimon. Keep Agumon in his mega form. Use DR Drive, Attack X2, Mega Drive (abilities), Invisible (item), and All Or Nothing (item). Keep attacking Lucemon until he faints. If both of your allies faint, Invisible wears off and you must revive them. When they are back, Invisible will return on Agumon.
