Freyr

is the God of Sun and the older brother of Freyja appearing in The Seven Deadly Sins: Grand Cross.

History
Freyr ruled Midgard for thousands of years along with his sister Freyja and the other Gods. However, as Ragnarok was coming, he started to grow weak and sick, forcing his sister to use their fairy subjects as sacrifices to replenish him.

Abilities
Freyr is a powerful god. However, the approaching Ragnarok weakened him over time, to the point of him struggling against King (who got his small wings at the time) with backup from Jormungand, Fenrir and Puca though both parties were holding back.

Freyja
Freyr deeply cares about his sister and convinced her to let King and the others go when they went to rescue their friend Helka.
