Description
Kratos Aurion began as a knight from Meltokio approximately 4,000 years before the main events. He joined Mithos Yggdrasill to end the Kharlan War. As Mithos's only human companion, he helped forge pacts with Summon Spirits and witnessed the Eternal Sword's creation, which cleaved the world into Sylvarant and Tethe'alla. After the war and Martel's death, he became a founding Four Seraphim of Cruxis. To compensate for lacking elven blood, he ingested Aionis, gaining magical abilities and transforming into an angel. He resided on Derris-Kharlan.
Centuries later, he descended to Sylvarant and met Anna Irving, a human subjected to the Angelus Project. They fell in love and had a son, Lloyd Irving. Pursued by Cruxis, Anna transformed into a monster during her Exsphere removal. She attacked Lloyd, forcing Kratos to kill her to save their son. Believing Lloyd perished in the aftermath, he returned to Cruxis in despair, supporting Mithos's plan to reunite the worlds.
During Colette Brunel's Journey of Regeneration, he appeared as a mercenary hired to guard her. He joined Lloyd's party, recognizing his son at Anna's grave. At the Tower of Salvation, he revealed his allegiance to Cruxis, delivering Colette to them and engaging the party in combat. His motives remained ambiguous; he both opposed and aided the group, such as helping destroy the out-of-control Great Tree against Mithos's orders.
His past was fully disclosed during the party's confrontation at Welgaia, confirming his identity as Mithos's ancient companion. Yuan later exposed Kratos as Lloyd's father, leading to Lloyd's denial. Kratos blocked a fatal attack from Yuan to protect Lloyd. In Flanoir, he recounted Anna's death to Lloyd, influencing Zelos Wilder's choice about Aionis. He then guided Lloyd to wield the Eternal Sword, dueling him at Origin's seal to release mana. Injured but forgiven, he survived after Yuan shared mana.
Following Mithos's defeat, he advocated ending Exsphere use due to their human cost. Exiling himself to Derris-Kharlan, he scattered Cruxis's Exspheres into space using the Tower of Salvation. Later, he communicated with Yuan via hologram as Derris-Kharlan drifted into space, bidding a final farewell during an encounter with Emil Castagnier and Tenebrae.
