Series & First Appearance
Xellos first appeared in the anime series Slayers NEXT, which aired in 1996. The character was created by Hajime Kanzaka, with designs by Yoshiko Nishikawa. Xellos has since maintained a significant presence in the Slayers franchise, featuring in various adaptations and spin-offs, including light novels and manga.
Profile at a Glance
Xellos is an enigmatic figure appearing to be in his mid-20s, but as a mazoku priest, he is technically over a thousand years old. He serves as an antagonist and occasional ally to the main characters, primarily to the protagonist Lina Inverse. Xellos is affiliated with Zelas Metallium, one of the five Demon Lords, and showcases immense powers, primarily through manipulation and deception rather than outright violence.
Personality & Motivations
Xellos embodies playful trickery and cunning intelligence, often deriving joy from chaos and deception. Known as the "Trickster Priest," he rarely lies outright but enjoys misdirecting others, frequently employing his famous catchphrase, "Sore wa himitsu desu" ("That is a secret") to maintain an air of mystery. His motivations often revolve around serving Zelas and exploring the myriad outcomes of situations rather than achieving traditional villainous goals. Unlike other mazoku, who embody pure malice, Xellos possesses a complex character that shows curiosity towards human behavior, particularly towards Lina, who consistently challenges his expectations.
Abilities / Powers
Xellos is considered one of the most powerful mazoku due to Zelas’s significant investment in his creation. He is nearly immune to most forms of black magic and is exceptionally fast, which allows him to evade attacks with ease. However, he holds a vulnerability regarding spells that call upon the power of the Lord of Nightmares. Instead of typically engaging in direct combat, he prefers to manipulate events from the shadows and let others carry out his plans for him. This proficiency in strategy makes him a formidable opponent, as he can often outthink his rivals rather than overpower them.
Major Story Arcs & Growth
Xellos plays a crucial role throughout the Slayers series, particularly during Slayers NEXT, where his true allegiance and objectives become a focal point. One significant turning moment is during the Kōma War, where he singlehandedly killed thousands of golden dragons, earning him their eternal hatred. His character evolves as he interacts with Lina and her companions, revealing a more nuanced side, particularly in the way he responds to Lina’s unique perspective on their battles. As the series progresses, the depth of his character becomes evident as his motivations and conflicting emotions are explored.
Notable Relationships
Xellos’s primary interaction is with Lina Inverse, a constant source of intrigue for him. Their relationship is characterized by a mix of mutual respect and playful antagonism, with Xellos often viewing Lina’s strong-willed nature as an engaging challenge. While the Slayers group generally distrusts him, his link to Zelas Metallium places him in a unique position of influence, further complicating his dynamics with both allies and foes. Other mazoku, such as his disdain for golden dragons, significantly shape his characterization and narrative importance.

This moment emphasizes his playful nature and cunning intelligence. Another iconic line is from Slayers TRY, where he comments, "I prefer to play games with my food," underscoring his predatory yet whimsical approach to his relationships with others. These quotes and scenes resonate strongly with fans, encapsulating his chaotic essence and adding to his enigmatic persona.
