Ricardio

Ricardio the Heart Guy makes his first appearance in the episode of the same name. The heroes first come across him bestowing a Best Friend Massage upon Lumpy Space Princess.

Finn shows a rivalry with him due to the fact that Princess Bubblegum seems somewhat attracted to him, and Finn has a crush on her. This is shown when Finn says to Jake, "I can't compete with that, he's talking about science!" This obviously made him jealous. Finn punches Ricardio in the face once he suspects that he is evil, because he was seen throwing Ice King into a dumpster and carrying rope and broken glass bottles. Ice King then reveals to Finn and Jake that after an experiment had gone awry, his heart left his body, and Ice King began to grow weak. He somehow managed to crawl to the Candy Kingdom and tried to convince Ricardio to return to his body. But instead, Ricardio dumps Ice King into a dumpster, and left him for dead. Ricardio's plan was to cut out Princess Bubblegum's heart and force it to marry him. His idea of the forced marriage was similar to that of the Ice King's usual plans. Ricardio ties up Princess Bubblegum later on in the episode and Finn and Jake save Princess Bubblegum. He is returned to Ice King's body at the end of the episode, and says that he will be back.

He then returned in Season 4 episode, "Lady & Peebles". Having decided he wants to marry Princess Bubblegum instead of just her heart, he escaped Ice King again and made himself arms and legs from Ice King's body. He hid in a cavern dungeon in the Ice Kingdom and kidnapped Finn and Jake in order to lure Princess Bubblegum to him. When she finally came, Bubblegum agreed to marry him if he could defeat her in combat. Since Ricardo was a heart (the weak point of a body) Princess Bubblegum was easily able to defeat him and he crawled off in defeat. His current location is unknown.

Appearance
Ricardio was the heart of the Ice King. However, instead of looking like an actual heart, Ricardio's body has the shape of the iconic heart symbol that means "love." Ricardio is fairly small, smaller than that of the small Candy People. He also has a very detailed face (unlike most of the characters seen in the show). He has bold eyebrows, eyes that are depicted as actual human eyes instead of dots, bold nose, wide lips, and cheekbones. Ricardio also possesses arms and legs.

When Ricardio created a new body in "Lady & Peebles", he used multiple veins and arteries to connect himself to bulging arms and legs. He also has a smiley face mask taped on top of his head.

Personality
Ricardio is the heart of the Ice King. Because of this, Ricardio possesses some major traits from the villain. Mainly, Ricardio has an obsession for princesses. Unlike the Ice King however, Ricardio literally wants the hearts of princesses, especially Princess Bubblegum's (as seen in Ricardio the Heart Guy); although in "Lady & Peebles", he claims that he didn't just want Princess Bubblegum's heart, he wanted "the full package (all of her). Some traits that Ricardio possesses that Ice King doesn't is that he's social and charismatic. The Candy People and the Princesses take a liking to Ricardio while they despise the Ice King. Ricardio can also be violent and heartless (ironically): for example, he twisted an unoconcious Lady Rainicorn's body (putting her unborn children at risk) to show off his new "body". He also beats up the Ice King (his host) and throws him into a dumpster and steps on him. This also proves that Ricardio has no desire to keep Ice King alive by being his heart; he wants a life of his own.

Trivia

 * Unlike Ice King, Ricardio is charismatic enough to become popular and well-liked among the Candy People and princesses.
 * His own name is a pun: Ricardo is "Richard" in Spanish, and cardio comes from cardiac, which means "of or related to the heart."
 * Even though Ricardio is an actual heart, he doesn't look like one. Instead, he just looks like the "Love" heart design. However, his early designs show him looking like an actual heart.
 * He is one of the few characters which have many details in the face, while the other, even the main characters, have a simple face.
 * Because he's the heart of Ice King, he should be at least as old as him. This was proven in the Adventure Time: My Two Favorite People DVD special feature "Little Did You Know." His species is shown to be a Human Heart, meaning the Ice King could still genetically be a human.
 * Ricardio seems to be too big to be the Ice King's heart, but later in "Ricardio the Heart Guy," he seems to shrink to the correct size.
 * Ricardio appeared later on in the series during a commercial on Flicks where Finn and Jake (along with various other characters from The Amazing World of Gumball, Adventure Time, and Regular Show) are in a movie theater, and Jake is annoyed by a beating noise. Later, it is revealed that the beating came from Ricardio, who was sitting next to Jake, watching the movie with a surprised look on his face.
 * On Ice King's papercraft robe, Ricardio's face peeks out a little bit.
 * In "Gotcha," Lumpy Space Princess has a binder with a picture of Ricardio on it.
 * In "Lady & Peebles," eyelashes and a more detailed face were added to Ricardio.
 * In "Lady & Peebles" Ricardio adresses the Ice King as "Simon" at one point.
 * In the storyboard for "Lady & Peebles", the smiling piece on his head was the head of Homer Simpson from "The Simpsons". It obviously was not shown on television because of the possiblity of a lawsuit by Fox Studios.
