Description
Omegaman Dexia, a bounty hunter from Planet Omega Centauri, serves Chojin Enma by capturing escaped prisoners from the Chojin Graveyard. He is the younger twin brother of Omegaman Aristera, king of Omega Centauri and leader of the Six Spears. Though nearly identical to his brother, Dexia possesses unique physical traits: a giant right hand on his back, a slightly different mask design, and a tail.

Sent to Earth as a spy, Dexia infiltrated the Perfect Chojin ranks. His mission was gathering intelligence on Chojin Enma and the elusive Magnet Power for Omega Centauri, while also studying Earth's weaknesses for his planet's strategic benefit. His combat prowess earned him recognition as a Perfect Chojin and consideration for the elite "Large Numbers". Under escalating orders to assassinate Neptuneman, he joined Super Phoenix's team during the Survivor Match for the Kinniku Throne.

Dexia maintains a stoic, professional bounty hunter demeanor, successfully capturing formidable fighters like Sunshine and Sneagator. He employs manipulative and cruel tactics, notably using his Omega Metamorphosis ability to transform into the deceased Prince Kamehame to exploit Kinnikuman's emotions. Despite this, he respects worthy opponents, encouraging Kinnikuman during their final battle. His loyalty remains exclusively to his brother, whom he views as his sovereign.

In the Kinniku Throne tournament, Dexia defeated Geronimo and Moaiman using his Omega Catastrophe Drop technique. He fought in a tag-team match alongside Super Phoenix against Kinnikuman and Neptuneman, culminating in Neptuneman's death. Dexia then battled Kinnikuman alone. After transforming into Kamehame, he inadvertently enabled Kinnikuman to master the 100 Special Techniques. Kinnikuman reversed the metamorphosis and defeated Dexia with the Muscle Spark, causing Dexia's prophecy page to burn and erase him from existence.

Posthumously, Dexia's legacy endured. Aristera revealed his full name, innate Omega Metamorphosis ability, and exceptional Chojin Kyodo—the highest among Omega Centaurians. Dexia's intelligence-gathering mission was part of the Six Spears' broader plan to acquire Friendship Power and heal their dying planet; his report on this power proved crucial for Omega Centauri's strategies. While Aristera denied seeking vengeance for Dexia's death, he blamed Super Phoenix for his brother's mission failure. Dexia's final act of trusting Kinnikuman influenced the Six Spears to seek understanding of Earth's Burning Inner Strength.
