Narrator: The final battle for the Infinite Ocean has begun as the Winx and their allies confront Tritannus and his mutants. Tritannus captured Aisha and absorbed her Sirenix powers to use to activate the Emperor's Throne but Bloom and Nereus, determined to save her and the Magic Dimension, will not let Tritannus get away.

• Bloom, Serena, Nereus, Flora, and Desiryee are chasing after the kidnapped Aisha. Meanwhile, the other Winx, Selkies, and Tressa are fighting the mutants.
  

Stella: Hit them back!
Flora: They need help.
Bloom: Go!
Musa: Deafening Chord!
Flora: Petal Hurricane!

• Flora joins in the fight with the other girls.
  

Illiris: Flora!
Bloom: How much farther to the Emperor's Throne?
Serena: We're almost there, Bloom.
Bloom: We must get there before Tritannus activates the throne.

• We see Aisha in the cell with Daphne, grunting as they're kidnapped. Tritannus is about to activate the Emperor's Throne.
  

Tritannus: At last, my dearest Icy.
Icy: Yes, at last, darling Tritannus.
Tritannus: Now that I have Aisha's Sirenix powers, I can finally activate the Throne.
Icy: And rule the Infinite Ocean as Emperor.
Tritannus: With you by my side, beautiful Icy, as my Empress.
Icy: I can't wait!

• Tritannus sits on the throne. He uses his trident that emits Sirenix power (who is Aisha's) and his trident began to glow red. Icy is concerned at this. A darkness wave blasts her away; It spreads all over the ocean. Pan back to the girls fighting with the mutants.
  

Tecna: Get ready, everybody!
Stella: They're coming for us.

• Mutants roar. The darkness wave passes. Girls groan. The mutants' eyes glow red.
  

Musa: What is happening?
Tressa: Look, the gate is opening!

• The mutants swim to the gate.
  

Flora: They're all leaving.
Stella: Wherever they're going, we're going too. C'mon, you guys!

• Stella and the others head to the gate. Back at the Emperor's Throne, Icy gasps as she witnesses Tritannus bulking up due to the powerful absorption.
  

Icy: Magnificent.

• Tritannus' eyes are fully glowing red.
  

Icy: Tritannus, I'm here. Ready to rule with you as your Empress.
Tritannus: My Empress? You are NOTHING!
Icy: But Tritannus...my love, you can't mean that!

• Tritannus blasts a red energy of light at Icy.
  

Icy: You promised me! You said I would be Empress. Tritannus? Tritannus!

• Tritannus suddenly gets out of control and begins to attack Icy.
  

Icy: Nooo! You are destroying me?
Tritannus: Only I rule here!

• He blasts red energy bubbles at Icy, but is protected by Darcy and Stormy's spells.
  

Darcy: Not so fast, fishboy.
Stormy: You're not the Emperor of us.
Icy: Stormy, Darcy! I thought you two weren't speaking to me.
Darcy: We're not...but your still our sister.
Stormy: And we're still...
Trix: The Trix! Dark Sirenix Convergence!
Tritannus: You cannot stand against me! Your powers are pathetic! I cast you from the Infinite Ocean!

• Darkness bubbles from Tritannus' trident blasts the Trix away.
  

Tritannus: And now for Andros.

Tressa: We are in my home waters, the ocean of Andros.
Tecna: Yeah, but what are we doing here?
Musa: Bigger question: What are they doing here?
Tressa: Oh, no. They're near the palace.
Flora: Aisha's parents, King Teredor and Queen Niobe.
Tressa: The only family that Tritannus has not harmed.
Stella: And we're not going to keep it that way. Let's go!

• Tritannus continues to spread the darkness wave all over the ocean, including Andros underwater. The waters of Andros began to flood.
  

Mermaid 2: The water is rising so fast!
Mermaid 1: It's going to flood the palace!

Mermaid 2: Look!

• Mutants have appeared to attack the mermaids.
  

Mermaid 1: Hold your position. We must defend Andros.

• The water rises up even more.

Niobe: Teredor, what's happening?

• Teredor climbs up the throne.
  

Teredor: Come, Niobe. Take my hand.
Niobe: Oh! What should we do?
Teredor: We must get above the water. This way!

• Teredor and Niobe jump on the stairs.
  

Niobe: Teredor, I'm frightened!
Teredor: Don't worry, my love. We'll be safe in the Tower. Come quickly!

Serena: No!
Nereus: Tritannus' powers are greater than ever.
Bloom: So we'll just have to fight harder. Serena, find Daphne and Aisha. We'll deal with Tritannus.

• Bloom and Nereus swim to the Emperor's Throne but are blocked by mutants.
  

Bloom: Dancing Flames! Go, Nereus!

• Her attack defends herself and hits the mutants. Nereus approaches to Tritannus.
  

Nereus: Tritannus! It's between me and you now, brother.
Tritannus: I have no brother.

Roy: Back off!
Mermaid 3: Thanks, Roy.
Roy: Oh no! Stand fast. Whoa!

• He fights off with the mutants. Another mermaid tries to fend off at the mutant, but gets thrown in the water.
  

Mermaid 5: Tissa, we're coming!

• Three mermaids use their staffs to aim at the mutant. The fourth one heads underwater to see another one. The other mermaid uses its staff to pummel the mutant underwater.
  

Mermaid 4: There are too many of them!
Mermaid 3: I know.
Tressa: But now there are more of us!
Mermaids 3 and 4: Princess Tressa!

• Tressa points at the Winx at the sky.
  

Stella: Hey.
Roy: The Winx!
Stella: Let's get this party started.
Flora: We can't hurt them.
Tecna: True, but we must stop them.
Musa: Deafening Chord!
Roy: Cool!
Flora: Spring Banner!
Roy: For Andros!
Mermaids: For Andros!

• The mutant throws the mermaid at Andros' Palace.
  

Tecna: Logic Net!
Stella: Nice! Light Diamond!

• Roy and Tressa fend off against the mutants.
  

Roy: Forward!
Tressa: Get back! Andros!

• She uses her sword to attack the mutants.
  

Roy: Winx, we'll hold them off. King Teredor and Queen Niobe are both trapped somewhere in the palace.
Stella: On it. Come on, you guys!

• The palace is almost completely flooded.
  

Teredor: Courage, my queen.
Niobe: Yes, Teredor.

• The water rushes in the top of the palace.
  

Teredor: Do not despair, my dear Niobe.
Niobe: Oh no!

• Teredor shuts the door. Niobe backs away slowly and the mutants burst in.
  

Teredor: Niobe!

• He finds a staff from the statue.
  

Teredor: Stay back, beasts!

• He knocks off a mutant. The Winx arrive.
  

Stella: Hey, you!
Flora: Gaia's Defense!
Musa: Wall of Sound!

• The mutants flee.
  

Flora: We have to get them above all this water.
Stella: And I know how. With your permission, Your Majesties.

• Stella uses her magic to make Teredor and Niobe escape from the flooded palace.
  

Stella: You'll be safe now.
Teredor: Thank you, Winx.
Musa: We'll make sure of it. Oh man! There are even more of them!
Tecna: We are never going to beat so many of them!
Stella: Yeah, but we've got to try. Let's go, Winx!

Nereus: Neptune's Sword!
Tritannus: Your puny weapon can't hurt me! I rule here. You are NOTHING!
Bloom: No! Dragon Kick! Dragon Punch! Lava Jab!
Tritannus: You cannot defeat me!

• Tritannus uses his trident on Bloom. Bloom shields it. She is knocked over.
  

Bloom: Go for the trident. We have to destroy the trident.

• Nereus fends off against Tritannus. He uses his sword to knock his trident over.
  

Tritannus: NOOOOO!
Bloom: Fire of Sirenix!
Tritannus: MY TRIDENT!!!

• Tritannus' trident is destroyed. Aisha and Daphne are free.

Aisha: Tritannus' pollution!
Daphne: It's gone.

• The cell's door disappears. Serena enters.
  

Serena: Aisha, Daphne! You're free!

• Ligea and Neptune are back to normal.
  

Nereus: Mother, Father!
Neptune: Nereus!
Ligea: You saved us!
Tritannus: I thought I would destroy all of you!

• Tritannus is turned back into his merman form.
  

Tritannus: But you have destroyed me.

Roy: Steady...

• A light flashes in the water. The mutants are painfully disappearing. The water rises back down, stopping the flood. The mutants are turned back into mermans.
  

Stella: Bloom did it!
Flora: And Nereus. Nereus did it, too!
Musa: They beat Tritannus!
Roy: Oh, it's over!

• Everyone cheers. Neptune and Ligea rise out of the water. Crowd cheers.
  

Tressa: Mother! Father!

• They hug.
  

Tressa: I'm so happy!

• Neptune and Ligea swim up to Teredor and Niobe.
  

Teredor: Brother.
Niobe: We rejoice that you have returned to us.

• Neptune bows. Nereus, Bloom, Aisha, and Daphne rise out of the water with a weakened Tritannus.
  

Teredor: Tritannus, you brought great evil to the Magic Dimension and all who live here. But through the efforts of many good people, you have been defeated.
Neptune: And now, my son, you must be punished for what you have done.
Nereus: Brother, do you have anything to say?
Tritannus: Only that I'm sorry I didn't crush all of you when I had the chance.
Ligea: Oh, Tritannus...
Teredor: Tritannus, you leave us no choice. We banish you from the Magic Dimension.
Neptune: You will pass through the Gate of Oblivion...

• Tritannus gasps.
  

Neptune: ...and you'll never return.

• Neptune's guards bring Tritannus to the Gate of Oblivion; the Winx and Daphne watch.
  

Bloom: The Gate of Oblivion.
Stella: Scary!
Aisha: He totally earned it.

• Tritannus resists a little, then enters the gate; it disappears.
  

Bloom: Oh!

• Bloom's Sirenix Box opens; her guardian comes out.
  

Bloom: Guardian of Sirenix!
Guardian: Dear Bloom, I am so proud of you. You have banished the deepest darkness, and greatly pleased destiny. What is your wish?
 Bloom looks at Aisha, who nods.
Bloom: I wish to break the Sirenix curse, and end its legacy...forever.
Guardian: Your wish, dear Bloom, is granted.

• The Winx gasp. Daphne glows as her physical body is restored. Bloom gasps.
  

Bloom: Daphne!
Daphne: Bloom!

• They swim up to each other and hold hands; they tear up and hug.
  

Bloom: Oh, Daphne...
Aisha: Woo-hoo!

Neptune: From now on, we will not be divided between sea and land, but united as one family.
Teredor: And with all the planets of the Magic Dimension.
Neptune: Let there be peace for all of us!

• Crowd cheers; fireworks go off. Bloom's families arrive with Daphne.
  

Vanessa: Where's Bloom? And the Winx?
Brandon: Where else?
Sky: Onstage!
Mike: But...there's no stage here.

• A stage rises out of the water with the Winx band on it.
  

Bloom: Hello, Andros! This concert is to thank everyone for all the support and help they've given us!

• Crowd cheers.
  

Bloom: And, I'd like to give a special thanks, and all my love, to my family!

• Crowd cheers.
  

Daphne: Best little sister in the known universe.
