Leo The Lion is a lion from the O.W.C.A. (Organization Without a Cool Acronym).
Leo the Lion was found in captivity, but thanks to W.A.F (Wild Animal Force). He was rescued by those humans, one of them are Animal Trainers, so he was trained to help the wild animals captured. One day, the team was attacked by evil elephants by the organization's enemy: Dr. Gene! Leo did his best to defend his owners and his colleagues. So he entered the OWCA as Agent L.
Agent L is somewhat a proatagonist in this series. He helps Agent P catch rogue agents and stop evil plots of LOVEMUFFIN.
