Forever Dekaranger (フォーエバー・デカレンジャー Fōebā Dekarenjā) is the fiftieth and final episode of Tokusou Sentai Dekaranger.
With DekaBase fallen and the technology of the Earth Dekaranger in the hands of Abrella, Ban and his five partner Dekaranger must make a final stand to figure out a way to take back their base and stop the evil black-market Alienizer once and for all.
With the Dekabase being taken over by Agent Abrella, the Dekarangers were able to split up and escape thanks to K-9. However they were not out of the woods as the Dekarangers are without access to their powers. While Tetsu holds off DekaBase Robo with DekaWing Robo, the other Dekarangers utilize their personal talents to overcome Agent Abrella's ploy. With their combined efforts they were able to foil Abrella's efforts. The six Dekarangers then assemble and defeat him once and for all.

- This is the first Sentai finale to use farewell greeting of Sentai teams, and will not occur again until the Finale of Kyoryuger nine years later.
