Shredder procures the mythical sword of Arthurian Legend — Excalibur — and plans on using it to blow the world back to the Dark Ages.
Tropes
- Beware the Silly Ones: Merlin acts like a Scatterbrained Senior who doesn't seem to know where he is half the time, but make no mistake that he's a Wizard who knows how to use his magic offensively.
- Cosmic Motifs: Merlin has crescent moons and stars on his hat, with a star shape at the end of his wand.
- Magical Weapon: Excalibur glows, fires lightning, bring stone lions to life and creates ripples in time that warps London back to Medieval Times. It's so dangerous that Merlin awakens from his eternal slumber to help the Turtles stop him.
