KishiRyuOh (Jp. キシリュウオー) is the primary Megazord of the 2019 Super Sentai series Kishiryu Sentai Ryusoulger. It is formed from the „Kishiryu" (Knight Dragons), the living dragon-mecha of the Ryusoulger team. Its base configuration, „ThreeKnights" (Jp. スリーナイツ), combines the three core Kishiryu of the lead trio: Tyramigo (a Tyrannosaurus piloted by Koh / RyusoulRed) serves as the torso and head, while Triken and Ankyloze – the Kishiryu of teammates Melto (RyusoulBlue) and Asuna – form the arms. In the American adaptation Power Rangers Dino Fury (2021–2022), Tyramigo corresponds to the T-Rex Champion Zord and the assembled robot to the Dino Fury Megazord.

As the „ThreeKnights" form, KishiRyuOh is the show's baseline combination, later expanded or reconfigured with additional Kishiryu (for example FiveKnights, which adds TigerLance and MilNeedle, plus larger super-combinations). Its signature play feature is the RyuSoul system: small collectible figures („RyuSouls") are inserted into Tyramigo to trigger combination announcements, sounds and lights. In robot mode KishiRyuOh fights with a sword as its main weapon.

The DX toy was produced by Bandai Japan and released in 2019 alongside the show. The three Kishiryu were sold as individually numbered items (01–03) that connect together into KishiRyuOh ThreeKnights. As is typical of recent DX lines, construction is predominantly ABS/PVC plastic with only minimal die-cast; the electronics housed in Tyramigo play sounds and voice clips activated by the inserted RyuSoul figures. This is the standard Japanese DX release, not a limited or recolored special edition. For Dino Fury, Hasbro issued its own, considerably simplified Zord toys that are not engineering-identical to Bandai's DX line.
