Leader of the Whack is the fifteenth episode of Power Rangers Dino Thunder.
A meteor's energy changes the Rangers' personalities.When a monster attacks, the Rangers defeat it with the help of Trent, who has been turned good by the meteor. The meteor is destroyed and is used to free Tommy from his amber casing, but finds himself trapped in his Ranger form.
Not to be left out, Mesogog sends a wimpy monster to get the meteor. As everyone fights, the meteor zaps them all with energy. When Mesogog's monster returns, he is shocked to discover that the monster has gone from wimpy to aggressive.
Hayley finds that the Rangers' personalities have also changed, revealing hidden parts of themselves: Conner becomes highly intelligent and hard-studying, Ethan starts working out a lot and arrogant and Kira turns into a fashionista (Other changes include Devin becoming the coolest guy in town and Cassidy getting nerdy and wanting to date him). The monster shows up in the city, and the Rangers battle it. They defeat it with their Super Dino Power. Mesogog punishes Zeltrax and Elsa for their failure with a psionic brain-blast and turns the monster into a giant.
Trent, turned good by the meteor's rays, helps the Rangers and destroys the monster. The Rangers destroy the meteor, turning themselves back to normal. They take a piece back to base. The energy from the fragment releases Tommy, but he now finds himself trapped in Ranger form.

- Early on in the episode the Rangers were talking about things that would opposite of what they would do, which later happens in the episode:
- For Conner, it was a side of intelligence, giving the viewers a clue that Conner isn't as boneheaded as he appears.
- For Ethan, it was a competitive side that came out, as he was seen being a workfiend and acting like an airhead (much like Conner McKnight.), giving the viewers a clue that Ethan isn't as much of a geek as he appears.
- For Kira, she became a Valley Girl, shopping excessively and worrying about her appearance, giving the viewers a clue that she has a side of her that enjoys doing girly things.
- This is the first episode that Trent didn't deepen his voice while he is in his White Dino Ranger form.
- The title probably comes from the song "Leader of the Pack" by "The Shangri-La's"
- This episode has a very similar premise to that of the Star Trek: The Original Series episode "The Naked Time" and the Star Trek: The Next Generation episode "The Naled Now". In both episodes spores are released that releases the inhibitions of the Enterprose crew of both shows (Spock acts with emotion, Kirk declares his love for his ship, ect.)
