Black Daizyuzin

is a Japanese Tokusatsu drama, the 49th and currently final installment in Toei Company's Super Sentai series. It is the sixth produced in the Reiwa era, and a commemoration of the 50th anniversary of the franchise. This is the only series to combine the motifs of modern, prehistoric, and mythical creatures. It is also the third special anniversary series, following Kaizoku Sentai Gokaiger and Kikai Sentai Zenkaiger.

The series premiered on February 16, 2025, joining Kamen Rider Gavv and later, Kamen Rider ZEZTZ in the Super Hero Time lineup on TV Asahi following Bakuage Sentai Boonboomger's finale. Upon concluding, a new Toei tokusatsu franchise called Project R.E.D. (Records of Extraordinary Dimensions) and its premiere entry Super Space Sheriff Gavan Infinity will replace Gozyuger in the Super Hero Time block, bringing the Super Sentai franchise to a hiatus.

Gozyuger started airing in South Korea as Power Rangers No. 1 Force.

The "Universe War" was a large-scale conflict involving 49 Super Sentai and their mecha against a threat known as Cladis. At the brink of defeat, the Sentai offered their powers, creating the "Sentai Rings" to summon the ultimate savior Tega Sword, who destroyed Cladis but also provoked the destruction and recreation of the universe with the rings scattered across the cosmos.
