Synopsis:
Superboy travels back in time to find three Red Kryptonite meteors. The first he locates in ancient Egypt where it transforms his body into a lion. He then becomes the model for the Sphinx. The next meteor he locates in the time of King Arthur. He helps Arthur draw the sword from the stone with super-magnetism which is granted to him by the Red Kryptonite. The final meteor transforms him into a double of Jesse James. He double-crosses the James gang, then is rescued by Krypto when a posse tries to hang him. Finally, he returns home to protect his secret identity from Lana Lang.
