Humanoid Evil God

Evil-God-class monsters (邪神級モンスター(じゃしんきゅうモンスター), Jashin-kyū Monsutā^?) are high-level monsters that inhabit the barren frostland of Jötunheimr. There are two types of Evil Gods: beast-types and humanoid-types. The most prominent Evil God is a beast-type named Tonkii.

Chronology

Fairy Dance Arc

They were first mentioned based on the sum of Yurudo that Kirito handed over to the Sylph and Cait Sith lords to fund their quest. They first appeared after Kirito and Leafa were transported to Jötunheimr by a trap, and Kirito and Leafa encountered a fight between a two-headed giant-type evil god and beast-type evil god. Upon Leafa's request, Kirito aided the beast-type evil god by luring them on ice and then cracking the ice, causing both evil gods to fall into the water, where the beast-type evil god had the advantage and thus managed to win the battle.

Caliber

During the Caliber events, the Evil Gods represent two different factions, the Humanoid type for Þrym, and the Beast-type as the one protecting Alfheim. A quest emerged offering Excaliber as the so-called reward for eliminating all of the beast-type monsters being eliminated. However, if this quest were to be completed, it would trigger an end of the world event, called «Ragnarök», that would lead to the giants invading Alfheim, while the players would only be rewarded with the Fake Sword Caliburn. An alternative quest was offered by Urðr to stop the frost giants by retrieving Excaliber from the frost giant castle, Þrymheimr.
