Exodus - S2.E42

With the BT System fully armed, the Resistance and Spectra head to New Vestroia to initiate a mass evacuation. Many Bakugan are sent to Marucho's house on Earth including the Resistance's. However, Drago decides to remain behind to ensure that everyone has been rescued, remarking how many lives have been lost to protect New Vestroia such as Nobilion, Wavern dying, and also the six Ancient Warriors surrending their powers to six normal bakugan. Helios chases after Drago, refusing to allow Drago throw away his life while Helios still has a score to settle with Drago. Drago and Helios agree to destroy the BT System themselves. However, their powers are not enough. So, in a last attempt, Drago lifts the BT System from the ground and lifts it up to the atmosphere. Just as the BT System detonates, Drago hears Wavern's voice telling him to not give up and that he cannot die yet. Drago, given new determination, absorbs the attribute energies from the BT System and evolves while easily destroying the BT System. He returns to New Vestroia, greeted happily by everyone excluding Spectra and Helios. Mira questions Spectra on their terms of partnership, but Spectra declares he works alone. Spectra returns to his ship and leaves, but not before Helios declares his continuing rivalry with Drago.
