Season 5
Lemmy was first seen with one of the guardians of Andros, when they were guarding the gate between Andros and Earth. Suddenly a large amount of toxic waste comes through the Gate with Phylla following behind. Phylla tells Lemmy to help her stop pollution before it makes things worse around Andros. They tried to use their powers, but oil still keeps floating towards the Andros prison, eventually being absorbed by Tritannus, who mutates the guards and steals Lemmy and Phylla's powers.

Lemmy and Phylla goes to see King Neptune and they tell him about Tritannus, only for Neptune's rage, which frightens Lemmy and Phylla.

Lemmy meets Bloom, Stella and Aisha  at Andros and she bonds with Aisha and regains her powers. She leads the Winx to Shimmering Shells, but she was knocked out by pollution and she woken up by the Winx.

She later introduces Illiris to Winx as they have traveled to Solaria and Illiris bonds with Stella.

She along with Phylla, Illiris and Nissa visit King Neptune again, to tell them about the fate of Ligea and Nereus in the hands of Tritannus, who turned them into Mutants. Tritannus then appears, sends his mutated minions to fight his father and Tressa, and turns them into mutants too. Lemmy, along with Phylla and Illiris escape him when Tritannus steals Nissa's powers. She and Illiris travels to Melody to aid Aisha, Musa and Stella. However, Musa was turned into monster by Tritannus. Lemmy then has an idea to try to bond Musa with Sonna and her plan works as Sonna regains her powers and removes the curse from Musa.
