Lyla

Lyla was the cousin and lover of Mr. Burns.

History
When Burns was in Paris, he met Lyla, who was his cousin. They fell in love with each other and Burns proposed to her after drawing a picture of her. She said no as he was too evil, leaving Mr. Burns heartbroken.

Years later, Mr. Burns started reminiscing about Lyla and asked Dexter Colt to find out about her. He found out that Lyla was still alive but was now a Buddhist nun. Burns went to meet up with her at The Peak Inn and Lyla told Burns that she was saving herself for him. Mr. Burns went into the bathroom to get ready but when he came out, he found that Lyla was dead. He tried to give her the kiss of life but she then turned into dust at his kiss.
