Dilgear

ディルギア

Dilgear was a half-beastman, half-troll who served as a henchman to Zelgadiss Graywords and his great-grandfather, Rezo the Red Priest.
Unlike Zolf, Rodimus, and Noonsa, Dilgear was genuinely violent in battle, going so far as to kill his enemies. Although Dilgear was under Zelgadiss's command, his ultimate loyalty lay with Rezo. Consequently, Zelgadiss was not surprised when the half-breed turned against the chimera after Zelgadiss severed ties with Rezo following Noonsa's death. In their first encounter, Dilgear found himself outmatched and retreated. During their second battle, when Zolf and Rodimus arrived, Dilgear believed he had been rescued; however, Rodimus stated that their loyalty was to Zelgadiss, not Rezo. Zolf seriously wounded Dilgear shortly thereafter, and his final words were: "Just wait until I come back to life!".
Due to his half-troll regenerative abilities, he did indeed return, but he never exacted his revenge. With nowhere else to go, he wandered into Zephilia and passed out from hunger. Luna Inverse, who frequently fed stray dogs and cats, found him and decided to take him in. He awoke chained in a giant doghouse in her backyard. To his horror, Luna renamed him Spot. However, feeling indebted to her for saving his life, he developed a sense of loyalty and remained her pet. Some fans mistakenly identified Dilgear as the beast form of Greater Beast Zelas Metallium. In reality, Zelas and Luna would be enemies, as the former is a mazoku while the latter serves the shinzoku.
In the manga, Dilgear appeared differently than in the original novels or the anime. Rather than being one of Zelgadiss and Rezo's henchmen, he was a bounty hunter sent by Eris Vrumugun, alongside Rahanimu and Vrumugun, to eliminate Gourry Gabriev and Lina Inverse. Strangely, Dilgear vanished shortly after his introduction. It is possible that he either fled or was simply killed off-screen.
