This article is about a/an ally turned villain in Uchu Sentai Kyuranger.

Quervo (クエルボ Kuerubo) was a warrior from the Karasu System and the late best friend of Tsurugi Ohtori from 300 years ago. He was thought to be murdered by Don Armage, until it was later revealed that he formed a pact with Don Armage and merged with his powers, becoming the current incarnation of Don Armage, referred to in official materials as Don Quervo (ドン・クエルボ Don Kuerubo).[1]

Quervo would later be killed by Tsurugi himself in a bid to stop him after Don Armage was driven out of his body.

Character History

He was first indirectly mentioned by Eris as one of the 88 warriors of 88 star systems assembled by Tsurugi Ohtori in the Argo to fight the threat of the evil Jark Matter. Space.23: Become My Shield!

Tsurugi first met Quervo while infiltrating a confinement camp on the Karasu System. Though Quervo had found an escape plan, he was unable to execute it successfully on his own despite his many attempts. However, with Tsurugi's help, they were able to liberate everyone who was captured in the camp. Tsurugi offered to work together with Quervo, as he believed that Quervo's intellect combined with his own ability would be essential in freeing the universe from Jark Matter's control. The two would become partners from them on. Space.44: Don Armage's Identity

To gain the alleigance of the warrior of the Cepheus System, Quervo and Tsurugi peformed a set of nine trials at the Kyulin Temple on Achoruk. Negatively comparing himself with his comrade, Quervo was disheartened as he believed himself to not be worthy of fighting alongside one as strong as Tsurugi. Tsurugi, however, pointed out Quervo's great intellect, which would save them on many occasions. Space.38: Flaming Spheres! The 9 Crisis Strike!

Quervo was the best friend of Tsurugi Otori who was offered to be their strategist aboard the Argo. However, Quervo offered to shield Tsurugi instead. Tsurugi shrugged it off, obviously not needing as he was immortal thanks to the Houou Kyutama.

After the other eighty-six warriors were slain by Don Armage, with Quervo and Tsurugi left to stand up to him, Tsurugi tried to do a risky move that can cost his life, which failed to defeat Don Armage. However, after that, Quervo chose to sacrifiec himself and take Don Armage's killing blow that was meant for Tsurugi. Quervo sacrificed himself and told Tsurugi that he has to save the universe, but deep down he took the blow so his name would be well-known throughout the galaxy..

Quervo's death left a huge impact on Tsurugi, as he decided to only fight alone as he was afraid to sacrifice another comrade. Space.24: I Will Be A Shield to Fight!


Attempting to turn key XII on planet Toki in the Tokei System, Tsurugi met and was engaged by an illusion of Quervo, whom he soundly defeated as Houou Soldier. Space.25: Planet Toki, the Boy's Determination!

Returning to the Kyulin Temple in the company of the Kyurangers 333 years after his original visit, Tsurugi related his prior visit with Quervo to Shou Ronpo when he held similar insecurities, dissuading him from retiring from the team. Space.38: Shocking! 9 Continuous Dangers!

During the mission on Planet Southern Cross, Tsurugi was temporarily trapped in one of the Southern King's illusions, seeing a vision of Quervo who proclaimed that Tsurugi was the one who had killed him. Seeing Quervo's blood on his hands, Tsurugi screamed in terror. Space.41: Infiltrate! Planet Southern Cross

It was later revealed that Quervo made a deal with Don Armage, following the latter's initial defeat at the hands of Tsurugi. Craving power of his own due to feeling inferior as he was not as strong as Tsurugi, Don Armage fulfilled Quervo's wish and inhabited his dying body, allowing both of them to survive into the present. As such, Quervo inherited Don Armage's powers, becoming the current incarnation of Don Armage.

Don Armage previously revealed his true identity as Quervo to Tsurugi during the Kyurangers' mission on Planet Southern Cross. Tsurugi was shaken in disbelief at this fact, and kept it a secret from the Kyurangers until Don Armage personally revealed himself as Quervo to the team. Proclaiming himself to be Don Armage, Quervo flew off and hinted to the Kyurangers that they would meet again on Earth.

Behind the Scenes


Quervo is voiced by Daisuke Namikawa (浪川大輔 Namikawa Daisuke), who previously voiced Absolute God N Ma in Mahou Sentai Magiranger and Engine Speedor in Engine Sentai Go-Onger. His suit actor is Toshihiro Ogura (おぐらとしひろ Ogura Toshihiro).


Quervo's name is likely derived from the Spanish word "cuervo", which means "raven". This is fitting with his place of origin, the Karasu System, which is based on the constellation Corvus, named after the Latin word for "raven".


  • His role in the backstory of Tsurugi is similar to Utsusemimaru's former lord Moshinosuke Iwaizumi, as both's deaths has a big impact on their personality.
  • His role as a companion to a Sentai Red Ranger is also a reference to Engine Speedor, who was partnered with Sosuke Esumi/Go-On Red.
  • His role as a Red Ranger's friend who later made a pact to the main villain makes him similar to Doctor Kemp from Choujuu Sentai Liveman. However, unlike Doctor Kemp, he was the main villain himself, being the host of Don Armage, instead of one of his commanders.
