Character story & background

Who is Mephistopheles Yōma?

Born from darkness, Yōma is the incarnation of a fallen god of time—also known as Kairos—in the world of Saint Seiya: Awakening – Knights of the Zodiac. Saint Seiya

Once a servant of time imprisoned in a human body, he broke free to spread chaos. Cruel and elegant, he manipulates time as others manipulate a blade. Saint Seiya

His arrival in the game

The SSA/KotZ community watched this character arrive like a silent cyclone. Videos showcase his massive AOE and “broken” gameplay. YouTube
When the Summon event was announced, the forums came alive:

“Yōma is the monster everyone fears but dreams of summoning.” YouTube

Fun facts

The name “Mephistopheles” evokes the demon from the Faust myth, “the one who does not love the light.” Saint Seiya
The wiki says that Yōma planted seeds of darkness in the hearts of several Saints before killing them, playing with time itself. Wikipedia
YouTube shows a “very hard pull” for Yōma, highlighting how obtaining this character has become a rite of passage for some. YouTube

The light faltered. The cosmos held its breath. Among the ruins of a forgotten temple, Yōma appeared—sharp silhouette, dark suit, a pocket watch slipping through the shadow of his fingers.
“Time has betrayed you all,” he murmured, his voice soft as a blade. “And I am the moment you never saw coming.”
He spun the watch: tick-tock… tick-tock… then everything stopped. Frozen rain suspended its drops in the air, birds held back their song, and the heroes froze in mid-stride. And he struck.
The wind of the past crumpled against him, and the echoes of ancient battles awoke. He did not simply kill: he erased, rewrote and reshaped the flesh of time.
When the moment resumed its course, Yōma was gone. The temple still trembled. The survivors wondered: “Was he a man… or time given form?”
For when Yōma opens the door, eternity enters. And whoever summons time may well end up trapped… in their own saber.
