Personal Data

  • Name: Leonard
  • Known Aliases: King Mudbeard
  • Group Affiliation: Bad Piggies
  • Allies: Pigs
  • Voiced By: Bill Hader


Leonard appears as a green anthropomorphic pig in a chubby build with dark green thick brows and a full beard. He also have black eyes. He first appears without a crown. Later when he steals most of the eggs along with the Pigs and to be taken in Piggy Island. Leonard is seen wearing a crown on his head adorned with rubies and sapphires as opposed only several sapphire gems. His first outfit is a white diaper where he was taking a bath. His second outfit is his red sporty attire and third and final outfit, Leonard wears only his King's red cape with white black fur trim collar along with his ruby and sapphire crown where he was crowned as king and declares that the he will be holding a feast to eat the Eggs.


Leonard seems to be very controlling, as demonstrated when he interacts with Ross, shaming him for messing up their entrance on Bird Island. He has no fears or doubts when going onto Bird Island and greets the Birds with confidence, and makes his entrance loud and obvious. 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 Blue Egg as Red manages to outsmart him before Leonard's Castle explodes.
