Clayface (LEGO Batman: The Videogame)

Basil Karlo became the murderous Clayface when he found out that a remake of his movie was being made and one of the characters in it was a character called Clayface. Basil donned the suit and killed most of the cast members. Batman and Robin stopped him. Later, two other clayfaces gave Basil there powers and became a shape-shifter made out of clay.
