Recurring characters

During the Bobobo-bo Bo-bobo saga, there are a few characters that do not permenantly stay with the group. Almost all of them are from the Maruhage Empire and cannot be classified as rebels. They do however assisst Bo-bobo and the gang, so they cannot be fully classified as villians. A large amount of them are minor characters, who were more popular than the others, and a small handfull were once some of Bo-bobo's greatest enemies!
