The Papyrox are Nighlok-like monsters created by Serrator from special sheets of paper using his large, finger-like claws. The first Papyrox appeared in Something Fishy, where it easily overpowered the Battlewing Megazord. After Antonio successfully drove off Serrator with his newly completed LightZord, he revealed the LightZord's Mega Mode, which destroyed the Papyrox.
The second Papyrox appeared in He Ain't Heavy Metal, He's My Brother, alongside some Moogers and Spitfangs. They were all destroyed by the teamwork of the Samurai Megazord, Claw Battlezord and Bull Megazord.
The third Papyrox appeared in Trust Me, alongside a pair of Spitfangs. While the Spitfangs were destroyed by the Claw Armor Megazord, the Papyrox was destroyed by the Samurai Gigazord, with Jayden Shiba using the Shogun Mode and Shogun Spear to power up its final attack.
- His counterpart in the Super Sentai series that Samurai was based on is Kirigami.
