Thunder Struck, Part 2
Airdate: November 20, 2004

The Rangers return to find the Dino Lab demolished and Elsa missing. They check the black box to find out that Zeltrax is responsible.		Not long after, they show up as Zeltrax unleashes his powerful Zelzord to attack Reefside.

Zeltrax holds Elsa captive inside the Zelzord as she tries to talk some sense into him.		The Black Ranger invades the Zelzord to save Elsa and stop Zeltrax once and for all, but he runs into the Triptoids.

Meanwhile as the White Ranger fights the Triptoids on the ground, the other Rangers use their Megazords to confront the Zelzord.		Kira rushes off to help Tommy and they both come to Elsa's rescue, but Zeltrax won't let them go without a fight.

Zeltrax powers up into his ultimate form, but the Yellow and Black Rangers are still finally able to destroy him.		Zelzord however remains too powerful for the Thundersaurus and Mezodon Megazords to stop on their own.

Tommy instructs them to summon all of the Dinozords to stop zelzord, but they must ultimately sacrifice the Dinozords before they are all destroyed.		Conner and Ethan barely make out alive, but it can't be over yet, can it?

Mesogog has survived and has absorbed enough energy from the Dino Gems to become a powerful monster.		"Dino Thunder, Power Up!" the Rangers call out as they morph into action to take down Mesogog.

Mesogog is too powerful for even the Battlizer and his DNA copies itself to make clones and four times the trouble.		The Power Rangers must summon all of their power from their Dino Gems to unleash an unstoppable power.

The Dino Gem power becomes a giant dinosaur of energy which devours Mesogog and all of his clones.		The Power Rangers Dino Thunder pose victoriously as Mesogog is destroyed once and for all.

The Rangers used all of their Dino Gem power to destroy Mesogog and they have returned to normal with their Gems as no more than artifacts.		Cassidy and Devin have been taping the entire battle and know their secret identities, but have decided to give up the tape, because of their friendship.

Tommy reminds the others that their lives may go back to normal, but they'll never be the same.		Devin and Cassidy show up at the prom together.

Conner arrives there with Krista, the "tree girl", because it's what's on the inside that counts.		Ethan brings Angela a girl he met standing in line for tickets to Asteroid Conquest 2.

Trent reveals that he will be going to art school in the fall, and Tommy has decided to live the quiet life, but we all know how that usually goes.		Elsa has taken over the position as the new principal, and Anton asks her for a dance with an old friend.

Tommy goes to the stage to introduce the band and gives everyone props for all they've been through during the year.		Kira is introduced and sings as everyone enjoys the dance and memories are shared.
