season 4 is not out in english yet but i know they havent made an appearance in it yet but i think they will cuz season 4 isnt complete yet and at the end of the movie the secret of the Lost kingdom the trix come back and the ancient evil witch ancestoresses sagte they would use their body's so they r either coming back in season 4 sometime oder they will make a whole new season 5 LOL
I think they wanted new characters for the Winx Club's enemies. Personally, I like them, but... They will be back for the Sekunde Winx Club movie, but I don't know about season 5. Nick is coproducing the Winx Club with Rainbow, now, so Du could try to ask them. Or, E-Mail regenbogen directly at email@example.com. If enough people ask for the Trix to be in season 5 and on, they will be. Come on, all Du fans!
The Trix got defeated during the last episode of Winx Club season Three. Therefore, they did not Zeigen up in season four. Yes, they will come back for the Sekunde Winx Club movie, Winx Club: 3-D Magical Adventure, being possessed Von the ancestral witches. Also, the Trix will appear in season five when Nick premieres it in September, it is known they will be with a new leader, if you're thinking Valtor no, he got vanished to the Under realm in his demon form.
