Ryusoul Gattai Kishiryuzin (キシリュウジン, frequently romanized "Kishiryujin") is a movie-exclusive mecha from the Japanese series Kishiryu Sentai Ryusoulger (2019), the Sentai team of the Ryusoul knights (RyusoulRed/Koh and others). It appears only in the summer film "Kishiryu Sentai Ryusoulger the Movie: Time Slip! Dinosaur Panic." Unlike the main Megazord KishiRyuOh, Kishiryuzin is built around the film-exclusive Kishiryu Dinomigo — a Ceratosaurus-themed Zord described in-story as the very first Kishiryu, created roughly 65 million years ago — combined with the two cobra-themed Cobrago. Because the mecha appears only in this movie, it was never adapted for the US series Power Rangers Dino Fury (Hasbro), so there is no official US/Dino Fury name. It is Japan-exclusive.

In combination, Dinomigo forms the humanoid torso, the two Cobrago become shoulder armor and a pair of blades (the "Knight ByuByu Swords"), and an enlarged ByuByuSoul serves as the head. Kishiryuzin is portrayed as an especially powerful dual-sword fighter, depicted as stronger than the standard KishiRyuOh. In-film figures cite roughly 50 m in height, about 2,400 tonnes, and up to 300 km/h. Who ultimately pilots the mecha in the film is not clearly documented across sources, so no fixed attribution is made here.

The DX toy was released by Bandai Japan within the "Kishiryu Series EX" assortment as "Ryusoul Gattai DX Kishiryuzin" (released 27 July 2019, roughly 5,500 yen MSRP). The set includes Kishiryu Dinomigo, both Cobrago, and a ByuByuSoul figure, and it plugs into the DX line's RyuSoul system: inserted RyuSoul figures trigger sounds, and the individual Kishiryu can combine with other models in the range. As is typical for the DX Ryusoulger line, the model is predominantly plastic (ABS/PVC); meaningful die-cast content is not documented for this set. Being a Japan-only release with no Hasbro counterpart and tied to a single theatrical film, it is a comparatively niche set that collectors encounter less often.
