Ultimately, Gabumon and Matt achieve a final evolution into Gabumon (Bond of Friendship), a manifestation of their matured connection that defeats Eosmon but hastens their separation. The film concludes with Gabumon and Matt cherishing their remaining moments together, accepting their parting as a natural step forward. Gabumon’s selflessness prevails as he prioritizes Matt’s growth over their partnership’s continuity.
