Clayface is the ninth episode of the first season of Batman.


The episode starts with Batman and Robin investigating the disappearance of a local man when they find a small puddle of clay in his house. Batman takes the clay back to the Batcave, takes a look at it, and discovers that it is radioactive. That night, Robin secretly sneaks out to do further investigating. He finds a footprint in the woods with another piece of irradiated clay in it. He sees more footprints, and follows them to a cave. A tunnel in the cave leads him to an underground area where he sees a giant monster made out of clay holding several people hostage inside a few cages. The monster notices him and attacks him, but Robin quickly escapes. Back in the Batcave, Robin tells the others what he saw. The apprentices return to the cave, but Clayface is gone. They decide to hide and wait for him to return, and eventually Clayface comes back with two new prisoners. The apprentices attack, but Clayface manages to overpower them. Batman suddenly arrives and ambushes Clayface, catching the monster off guard. The apprentices free the prisoners and escape, as Batman asks Clayface why he's doing this. Clayface explains that he used to be an actor named Basil Karlo, until he lost his job one day. He robbed several banks, but the cops eventually found him and chased him down to the cave in the woods, where he fell in a gigantic puddle of clay irradiated by toxic waste and seemingly drowned in it. The police tried to retrieve his body, but the huge pool of clay was too deep. After a while, Basil eventually came out, mutated into a huge clay monster. Basil decided to capture everyone in Gotham and use the clay to mutate them into clay creatures so nobody will ever consider him a freak. With Clayface distracted, Batman quickly kicks him and knocks him into a cave wall, which crumbles and causes the cave to collapse. Batman escapes before the cave caves in, and takes off in the Batmobile as the police arrive.
