Appearance
Mudbeard appeared 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.

His second outfit is his red sporty attire and third and final outfit, Leonard only wore his royal red ermine robe with a white-and-black fur-trimmed collar as well as his royal crown, at his coronation.

Personality
Mudbeard seemed 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. He is also evil, murderous, aggressive, power-hungry and violent

Leonard's description from 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, he was 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 the Pig Palace exploded. It was later revealed he survived the attack and danced to "I Will Survive" with Ross and the survivors of the explosion.

Death and legacy
Multiple years after taking the throne, the king died and mourning was held, with his son, Smoothcheeks succeeding him as ruler. His legacy remained as the first pig to actually retrieve eggs, and beginning their ongoing conflict, the Great Egg War, with the Birds. He was perhaps buried in a cemetery or a crypt in the Pig Church.

His portrait remains, to this day - at the throne room of the Pig Palace, in the newly reconstructed Pig City; alongside the portrait of his wife.

Behind the scenes
According to The Art of the Angry Birds Movie, Francesca R. Natale, the character designer for The Angry Birds Movie, decided to design Leonard such that he would resemble the Roman emperor Caracalla, reflecting upon her Italian heritage.

 I grew up with a framed pencil drawing of a marble bust of a Roman Emperor, Caracalla, which was hanging in my family house in Rome. The drawing was made by one of my great-grandfathers at the end of the 19th century. While growing up I dreamt of one day being able to draw that well. While drawing Mudbeard for Angry Birds, I designed his beard as a specific tribute to that drawing.
