Beezen is the main antagonist of the My Little Pony two-part episode "The Revolt of Paradise Estate". He is an evil sorcerer who seeks to take over Paradise Estate.
Beezen was a traveling salesman who sold Paradise some magic paint that he said would fix Paradise Estate. The paint brought all of the furniture of Paradise Estate to life, along with the door, a floorboard, and a fence board. The furniture kicked the ponies out, allowing Beezen to move in and take over Paradise Estate, where he enslaved the furniture.
As the ponies found out about Beezen and made their way back to Paradise Estate, Baby Cuddles convinced the furniture to turn on Beezen, since they preferred the ponies over him. However, Beezen turned the furniture back to normal. As Beezen was about to destroy the ponies with his magic wand, Paradise threw the bucket of magic paint on his wand, which came to life. As revenge for "enslaving" it for centuries, the wand chased after Beezen, shooting deadly magic beams at him.
It is unclear whether Beezen escaped or whether the wand eventually killed him, but he has not been seen since.
