Leonard's description from Lego Angry Birds Movie, the Lego website:
Take an international ambassador, and combine it with a used car salesman, that’s Leonard. He is charming and charismatic, he speaks with confidence and enthusiasm, and he just might be full of baloney and hogwash, depending on who you ask. But with a personality like that, you can’t help but fall for his charm.
During their stay at Bird Island as his plans of stealing the Eggs is ready to engage, Leonard is shown to be obsessed with just one Egg as he imagines himself with an Egg. He also noticed Red's suspicions about his plans of stealing the Eggs as he makes Red as his enemy which they are seen fighting for the egg which would later hatch Jay, Jake, and Jim as Red manages to outsmart him before Leonard's castle exploded. It was later revealed he survived the attack and danced ''I Will Survive'' with Ross and some other piggies.
