Leon Feast is a character in Hard Luck. He would often kick Greg and Rowley out of the basketball court so he could play basketball with his friends. This made Greg angry, so he and Rowley joined The Superhero Training Academy at YMCA, which turned out to be a scam. Later, Greg takes Leon's yearbook picture and decreases his head size on the computer to get revenge.
