Deathgaliens
The Space Outlaws Dethgalien are a group of alien rogues who travel around the universe in a starship called the Sagittariark to hunt life on other planets for sport as part of their Blood Game, with the winner chosen by who ever amuses the owner the most. They choose Earth as the venue for their 100th Blood Game due to its apparent lack of defenses, only to encounter and eventually be disassembled by the Zyuohgers.

Ginis
Ginis is a conglomerate of countless Moebas, the owner of the Dethgaliens, and host of the Blood Games who normally resides within the Sagittariark as he is dependent on its power supply. After choosing Earth and losing one of his Team Leaders, Jagged, to the Zyuohgers, Ginis offers his remaining Leaders, Quval and Azald, a special prize for eliminating them. Following multiple failed attempts, Ginis grows bored until Bangray arrives on Earth to hunt Cube Whale. The former tasks Naria with using Gift Custom to compete with Bangray and collect data on Cube Whale, but the Zyuohgers destroy the machine. Despite this, Ginis has Naria save its data, which he later uses to absorb Earth's energy and evolve into Shin Ginis to thwart Quval's attempt on his life. When the Zyuohgers kill Quval and Azald, Ginis decides to end the Blood Game himself by using his cells and the Sagittariark to destroy Earth. While the Zyuohgers destroy the starship, Ginis survives to implant his cells directly into Earth and challenge them to stop him before he destroys the planet. During their fight, he reveals the Blood Games were a means to prove himself as a superior life form, though the Zyuohgers discover his secret. A livid Ginis kills Naria for being nearby when this occurred and enlarges, only to be destroyed by Wild Tousai Dodeka King.

In his original form, Ginis can spawn silver Moeba Medals so his Players can summon Moebas to assist them and upgrade Moeba Medals into gold Continue Medals so his Players can be revived and enlarged. After evolving into Shin Ginis, he gains a pair of wings capable of firing lasers, a pair of swords generated from his arms, and the ability to fire a beam from his palm capable of enlarging Players.

Moebas
Moebas are amoeba-like extensions of Ginis who are created from Moeba Medals to serve as the Dethgaliens' foot soldiers. They also pilot pyramid-like Triangular fighter crafts.

Gift
Gift is a powerful robotic war machine that Ginis created, but rarely uses in his Blood Games to avoid making the proceedings too one-sided. It is capable of enlarging itself and possesses several weapons at its disposal, such as the Ablation Railguns, which can destroy entire planets. It is eventually destroyed by Wild Zyuoh King. Ginis later creates the upgraded Mass-Produced Gifts to protect the Sagittariark during his attempt to destroy Earth, though the Zyuohgers destroy them all.

Naria
Naria is Ginis' smithsonite-themed secretary who is usually tasked with bringing Continue Medals to fallen Team Leaders and Players in order to revive and enlarge them. While helping enact Ginis' endgame however, she enlarges herself to protect the Sagittariark, but the Zyuohgers defeat her and cause her to revert to her original size. When she learns her master is composed of countless Moebas, which he had kept secret, she accepts him for what he is and resolves to continue serving him. However, he takes her compassion as an unacceptable insult and kills her.

In battle, she wields the Nunchacrusher nunchaku, which can also be used as a gun.

Gift Custom
Gift Custom is an upgraded version of Ginis' original Gift war machine that is armed with the Big Pile Launcher and the 12-Tube Missile Pod. Instead of being automated, this model is piloted by Naria. It is destroyed by DodekaiOh, but Naria escapes before then, taking with her a record of battle data that Ginis later uses to evolve into Shin Ginis.

Azald
Azald is a hot-tempered Boleite-themed Team Leader who enjoys making his victims suffer physically and employs Players who utilize brute force. He was originally Azald Legacy, an ancient monster who referred to himself as the Cosmic God of Destruction and attacked Earth in the past before he was driven off by Cetus. Following this, Azald was found by Ginis, who reconstructed the latter into his current form. Initially watching the 100th Blood Game from the sidelines, Azald personally battles the Zyuohgers after they free Ginis' Extra Player, Misao Mondo, from the Dethgaliens' control. After Bud uses the Whale Change Gun to wound him, Azald regains his memories and full power as Azald Legacy, breaks off from the Dethgaliens, and attempts to destroy Earth. However, the Zyuohgers discover his weakness and eventually destroy him permanently.

In battle, Azald wields the Azald Natta great sword, possesses a durable cuboid body, and is functionally immortal so long as his core remains intact. As Azald Legacy, he can destroy his surroundings with simple gestures.

Quval
Quval is a cautious bismuth-themed Team Leader who enjoys making his victims suffer mentally, employs Players who rely on strategy and deception, and is the sole survivor of a world the Dethgaliens destroyed, having joined them under false pretenses to seek revenge. While battling the Zyuohgers and pursuing his goal, Quval slices off Bangray's hand and attaches it to himself to make use of the latter's mental powers before mounting an attempt on Ginis' life. When Ginis thwarts this however, Quval returns to him and tries to earn his forgiveness by personally killing the Zyuohgers. Despite receiving five Continue Medals to enlarge himself and significantly increase his power, Quval is destroyed by Wild Tousai Dodeka King.

In battle, Quval is armed with the Fasticker, which has a blaster and rapier mode, the Switchusha injector, and the Voltaic Knuckle gauntlet.
