Lady Rainicorn's Trivia

Lady's toy version, as seen in "All the Little People," has a different color scheme than she normally has.

In the Tamil dubbing episodes, Lady Rainicorn speaks in Malayalam (a language similar to Tamil), so the viewer can sometimes understand whats she's speaking.

In one room of the Princess Bubblegum's castle, there are two pictures of Lady Rainicorn on the wall; one of her upper half, and one of her lower half.

Two Rainicorns (both of which look like Lady) appear in the Double Rainbow promo.

In "The Real You," Princess Bubblegum is seen in the beginning with a yellow t-shirt with a red Rainicorn on it.

Lady Rainicorn has a gender-swapped counterpart in the Ice King's fan-fiction: Lord Monochromicorn.

Her favorite drink is iced latte as shown in "Video Makers."

In "My Two Favorite People" Jake refers to her as "the rowdy queen."

In "Apple Thief" Jake cooks Finn traditional Korean food that Lady Rainicorn taught him how to make.

Despite being based on a rainbow, Lady Rainicorn's body does not display any orange, but in the animated short she had orange on her body.

In "Burning Low," Jake implies that her stomach is 15 feet long.

In "Card Wars," it is revealed that Lady Rainicorn used to play Card Wars with Jake, and it made her mad that Jake always won and wanted to do nothing but play it.

She can speak some English words, as shown in "Lady & Peebles":"I am pregnant!"

As shown in "Lady & Peebles," five small dots and two larger dots appear on the heart monitor. This shows that Lady was pregnant, and the five dots indicate her children, who would make their first appearance in "Jake the Dad."

Lady has a recurring nightmare about zombies attacking her family. The stress causes her to grind her teeth in her sleep.

In "My Two Favorite People," Lady is able to wear power rings by phasing them to her hands.

The original storyboards from this episode also featured Lady explaining to Finn that she was from another universe and came to Ooo by accident when a cluster of moons inverted and "black holed" into each other.

This is apparently not canon, as her parents are shown to be from the Crystal Dimension and are able to travel to and from Ooo freely, and other Rainicorns are known to people in Ooo.

Lady's colors are in reverse order when compared to a normal rainbow.

Contrary to popular belief that Lady speaks English in Korea, Lady's voice is dubbed over in Korean by voice actor Lee Myung-hee in Korea. For the reason other characters don't understand her, her voice is digitally distorted, though it is easy for viewers to understand her.

Lady Rainicorn appears as an Enchiridion spell in "Finn and Jake's Epic Quest."

She also appears as a power-up by Finn riding her to go higher in "Jumping Finn."

In the animated short, she speaks a possible Rainicorn language, but in later episodes she speaks Korean

In a translation in "Lady & Peebles," it says that Lady enjoys bird songs.
