|Introduced in||"My Two Favorite People"|
The Lake Knights make their only appearance in "My Two Favorite People." When Jake tries to spend more time with both Finn and Lady Rainicorn at the same time, he realizes that this can only be done if he fetches the Universal Translator that he threw into the lake. The Lake Knights guard the lake, translator, and a massive pile of doubloons and treasure (which remained untouched by the trio) with swords that resemble lightsabers from the Star Wars Saga. After fighting off a horde of Lake Knights, the three get the translator and safely leave. They have dark blue skin and a light blue stomach. They also have a purple cone on their head, and instead of eyes, they have asterisks. According to Finn, they are evil.
