Leo was the Head Chef and owner of Avante-Garde Cuisine, and also a shaman.
The spells he used, caused him to take on the physical characteristics of the animals whose organs he consumed. However, the effects were only temporary, which resulted in his experimentation in "combination therapy," which made him stronger and caused the effects to last longer.
He was confronted by Sam and Dean Winchester. He swiped at Sam and caused him to bleed at the neck. Gadreel, then known as Ezekiel, momentarily took over Sam and healed him. Leo was intrigued by Sam's ability and wanted to eat him and cure his cancer. He overpowered Dean and bound him. He reveals that he didn't intend to kill any people, but killed those who went against him. Dean escaped and again tried to engage him. Being unsuccessful, he lured him outside where a pack of dogs killed him.
