Lord Monochromicorn is the gender-swapped version of Lady Rainicorn created by the original series designer Natasha Allegri and is featured in "fFionna and Cake". He is the loyal companion of Prince Gumball and the boyfriend of Cake. He communicates by using his foot like a telegraph to communicate with Morse Code, rather than speaking Korean, as Lady Rainicorn does. (He stomps his hoof for a dot and scratches the floor like a line for a dash).
