Helos is a figure of Marleyan legend, renowned for slaying the Devil of All Earth. The story of Helos was fabricated by the Tybur family and Karl Fritz to worsen the Eldian civil war, and it is unknown whether or not Helos ever truly existed.
Helos has been described in legend as a beautiful man. In his statue in Liberio as well as Willy Tybur's play, Helos wears a feathered bicorn hat along with a soldier's tailcoat and breeches.
According to legend, Helos was a brave and heroic man, willing to face off against the Devil of All Earth despite the overwhelming odds. He was also clever and cunning, able to fuel the in-fighting among the Eldians and bring about the fall of their empire.

History: When he inherited the Founding Titan, Karl Fritz decided to conspire with the Tybur family to send Eldia on a path towards destruction as retribution for the atrocities the empire committed throughout humanity's history. As part of this effort, the Fritz and the Tyburs instigated the continuing Eldian civil conflicts by fabricating a Marleyan hero known as Helos.
How Helos echoes later: In the aftermath of the Marley Mid-East War, the Tybur family visits Liberio shortly before a festival in which Willy Tybur, head of the household, is to address an international press conference. During this visit, Willy admires the statue of Helos slaying the Devil and later expresses his fondness of the hero to Commander Magath. However, Magath is less impressed with the display, considering it to be as hollow as Marley's reputation.
