Robotack's Death at Sea (ロボタック海に死す Robotakku Umi ni Shisu?) is the 45th and final episode of Tetsuwan Tantei Robotack. As Robotack was the last installment in the Metal Hero Series, this was proved to be the final overall Metal Heroes episode. However, the franchise would be revived in 2012, the 30th Birthday year of the Metal Hero Series and the original Uchuu Keiji Gavan with Kaizoku Sentai Gokaiger vs. Uchuu Keiji Gavan: The Movie (January 2012) and then Uchuu Keiji Gavan: The Movie (October 2012) which introduces Gavan Type G and the next generation of the Space Sheriffs.
