Oblivion is a realm shown in the Season 2.

In Season 2, after Darkar turns Bloom into Dark Bloom, the Trix ask him a share of the Ultimate Power that he will obtain in the Realix Dimension, telling him that they do not expect to be treated as simple pawns of his. Darkar then betrays them and bans them to the Realm of Oblivion, telling them that they were indeed his pawns. There, the Trix fuse into the Mega Trix and go to seek revenge from Darkar in Realix.

After Bloom is healed and turns back from Dark Bloom to her former self, Darkar threatens to ban the Winx, the Specialists, Faragonda, Griffin and Codatorta into Oblivion.

Tritannus, who was the villain in Season 5 was banished here at the end of the Season 5.
