Season 5
In The Rise of Tritannus, Tritannus stole the powers of the gatekeepers of the portals that connect the ocean of Andros to the oceans of all the realms of the Magic Dimension, namely those of Andros and of Earth and he vowed to do the same to all the members of their kind so that he will be able to enter the Infinite Ocean and activate the Emperor's Throne, which will allow him to conquer the whole Magic Dimension.

In The Emperor's Throne, after entering the Infinote Ocean with the Trix, his mutants and Daphne as his prisoner, Tritannus tried to activate the Emperor's Throne but failed and tried to damage the Throne with his trident, causing the Throne to attack him, and had Daphne imprisoned when she warned him of the dangers of the Sirenix he stole from her.

Because the attack by the Emperor's Throne drained him of his powers, he had to go to Earth with the Trix to refuel his powers. however the Winx found them, and when Tritannus and the Trix fled into the Infinite Ocean the Winx followed them, surprising the Trix and Tritannus. When the Winx tried attacking Tritannus, he showed them Queen Ligea. King Neptune, Nereus and Tressa, turned into mutants, and told the Winx that they will have to destroy Aisha's family to destroy him, and he ran away with the Trix to activate the Emperor's Throne.

Later, when inspecting the Throne to find out why it was not working, Tritannus found out that the legs of the Throne were broken and decided to steal the seals of the Pillars of the Infinite Ocean and fit them where the leg of the Throne was broken to repair it and activate it. When he took the seal of the Pillar of Light this caused an eclipse in the whole Magic Dimension that made all the realms unstable/
