A New Knight / Conclusion! The Strongest Mode

S1, E26: The Tenkai Knights take on Vilius and the Tenkai Dragon's evil side in an epic battle. Dromus decides to join Bravenwolf alongside the other Guardians. The Dragon is split back into five cubes that fuse with the Knights (and Dromus), gaining the Phoenix mode with the power to destroy Vilius for good and restore the portal.
