Zoro, the Mystery Man – Who he is – Whence he comes – Whether he goes – Nobody knows who fought evil with a sword cane and a cheetah named Cheeta.
No one knew who he was or where he, or his big cat, came from, they would just show up and Zoro would soon take care of the most pressing bit of evil, often with deadly force, and then the pair would drive off as mysteriously as they had appeared.
Zoro fought evil using only his wits, his fists, and a sword cane, Cheeta of course often helped out.
