The Kojishi Voyager (コジシボイジャー; "Leo Minor," the lesser lion) is an auxiliary mecha from Uchu Sentai Kyuranger (2017, the 41st Super Sentai series). It belongs to Lucky, leader of the Kyurangers and bearer of Shishi Red (Leo). Its footage was later reused in the Western adaptation Power Rangers Cosmic Fury (2023), but no dedicated Power Rangers toy was released for it. In the story the Kojishi Voyager is a gift from Lucky's father, King Aslan; Lucky nicknamed it "Caesar." It normally exists in a palm-sized miniature form and is enlarged to battle scale via the Kojishi Kyutama. It is not a standalone main Megazord but a lion-shaped auxiliary/support Zord that expands the existing KyurenOh system.

Combination and battle mechanics: The Kojishi Voyager docks onto the Shishi Voyager (Shishi Red's core lion mecha) to form the Super Shishi Voyager. Within the larger Kyutama Gattai combination it upgrades KyurenOh into Super KyurenOh, chiefly contributing a powerful cannon and a marked boost in firepower; the added module also multiplies the number of possible Voyager arrangements (with Kojishi attached, the Washi Voyager can no longer serve as wings). Its defining traits are thus its power-up role and its miniature-to-battle-size transformation.

DX toy: The DX model was released by Bandai (Japan) on 2 November 2017 as "Kyutama Gattai 77 DX Kojishi Voyager" — Japan-exclusive, with no separate Hasbro/Power Rangers release. It is a smaller add-on set that combines with the Shishi Voyager from the DX KyurenOh to form the Super Shishi Voyager and, together with five Kyutama, enables the Super KyurenOh build. The matching Kojishi Kyutama is included. Like the rest of the Kyuranger DX Voyager line it is made mostly of plastic (ABS/PVC); no significant die-cast content is documented. The set is discontinued and available only on the secondary/collector market.
