Lemonhope

"Lemonhope," also known as "Badlemonnohope" (voiced by Justin Roiland) is a Lemon Child who was formerly imprisoned in Castle Lemongrab. Lemonhope first appears in "Too Old," where he escapes from the Earl of Lemongrab with the help of Princess Bubblegum, Finn, and the Lemon People. He eventually returns to the castle to free his people from their oppressive ruler, but departs soon afterward, seeking to live his life in freedom.
