Season 5
At Gardenia in planet Earth, an oil spill occurs and oil floats its way deep into the ocean, eventually researching the Gate of Earth, which is guarded by Phylla and one of Andros triton guards. Phylla tries to stop oil with her magic, but oil appears to be immune to her powers and so it enters the Gate to Andros, where Andros gatekeeper Lemmy and Phylla try to stop it again. After stealing Lemmy's and Phylla's powers, Tritannus decides to seek all other gatekeepers in order to enter Infinite Ocean and rule the Magic Dimension. To do this, Tritannususes Gates to reach other worlds and their gatekeeper selkies their powers and control their Gates. So far Tritannus uses Earthgate the most, in case he runs out of toxic that grants him his powers. He would send the Trix ahead to dumb toxic into the water or sabotage oil plants. He himself would use the gate to go adsorb this toxic. The Winx haven't used any of the gates yet as they prefer using magic.

Trivia

 * It is unclear if the Infinite Ocean has a gate or not. It may have, but it may also require powers of many selkies before it is possible to enter.
