Bellok

Berlock is an elderly vampire bat who is the caretaker of Worst Castle, which is supposedly Sonia's ancestral home. He has a pet owl called Hooter who he is very found of. He cannot stand loud noises and is very humorous. His catchphrase is "I am Berlock, the castle caretaker." He speaks in the classic vampire accent. Berlock was forced by Sleet who "threatened to eat Hooter" into helping him set a trap for the Sonic Underground, but after confessing all to the hedgehogs, he helped them escape the castle through a dimensional mirror and survived the collapse of the castle. Berlock is actually an agent of Queen Aleena, as seen when he acknowledges her presence nearby.
