The Rat King is character introduced in "Little Brother." He is, of course, the king of the rats. Kent went on a quest to defeat him by breaking of his teeth to protect Finn and Jake's tree house, and he apparently succeeded.
The Rat King is a white rat with a crown. The crown has a single blue gem in it. His tail is pink as well as his eyes, and he posseses long, glowing white teeth that are seen releasing a poisonous green smoke. In the final battle between Kent and the Rat King, the Rat King wears a cloak and has blue mist coming out of his mouth. When he was seen earlier in the episode, he appeared to be a normal rat but with a crown. Later in the episode, he could talk and his body under the cloak was made up of a horde of rats.
