The battle is intense and Dan and Drago are pushed to their limits. However, they are eventually able to defeat Masquerade and destroy the Silent Core. With the Silent Core destroyed, Earth is saved and the Bakugan are able to return to their home dimension.
In the final scene, Dan and Drago say goodbye to each other and Drago returns to the Bakugan dimension. Dan is sad to see Drago go, but he knows that they will always be friends.
The last episode of Bakugan: Battle Brawlers is a bittersweet one, but it is also a fitting end to the series. It is a story about friendship, courage, and the power of good to triumph over evil.
