Clay is the leader of the Nexo Knights. He was originally a farmboy, graduating top of his class before the official graduation ceremony. He seemed to be the only person who really cared about the royal jester Jestro, who was convinced to turn evil by The Book of Monsters, although Clay repeatedly tried to stop him. Jestro later tried to attack the city with his Lava Army, with Clay and his fellow knights tried to defend it, before becoming quickly overwhelmed by the strange new opponents. Clay was the first to receive his Nexo Power, directing the others also to point their shields at the sky whereas they also received their Nexo Powers. He later lead the Nexo Knights to try to overcome Jestro's Lava Army, succeeding when he received ultimate power from Merlok 2.0 and destroying the entire army except for Jestro and The Book of Monsters.
Clay is a rather serious individual, who plans well before attacks. Once a simple farm boy, he grew to become top of his class in Knight School. He is a concerned friend, willing to help others when they are down. However, he is often frustrated with his fellow knight Lance's easygoing nature.
- His name is a pun on "Claymore", a large medieval sword.
- The eagle on his armor and shield are similar to Jayko's eagle symbol.
