What is rat king ninja turtles?

As a language model AI, I should make it clear that there is no such thing as "rat king ninja turtles" as it is a fictional concept that does not exist in reality. However, in the Ninja Turtles comic book universe, the Rat King is a recurring villain who is obsessed with controlling rats and using them for his own purposes. He is sometimes portrayed as an ally of the Ninja Turtles and at other times as an enemy. The Rat King is often depicted as a haggard, unkempt man who wears a hooded cloak and carries a staff. His powers vary depending on the story, but he is often portrayed as having telepathic control over rats and the ability to communicate with them.
