Evil Gods

Evil God-class monsters (邪神級 (じゃしんきゅう) モンスター) 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.

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.
