Patience St. Pim is understood to have lived thousands of years ago, before the Great Mushroom War. She was the reincarnation of the ice elemental who, along with the other elementals of her era, had visions of the Lich's arrival. These visions came with the understanding that the world was going to go through an epic cataclysm that the elementals knew they probably wouldn't survive. Patience, wanting to live through the cataclysm, sailed into the ocean and covered herself in an ice sphere where she would stay dormant for a number of years until she would later be discovered by Ice King, Finn, and Jake.
In "Elemental," after being released from her ice sphere, Patience freezes Finn and Jake and instructs Ice King fetch her the other elementals (Princess Bubblegum, Slime Princess, and Flame Princess in this cycle). Finally reunited with the other elementals, Patience shows them their potential and attempts to unite them, but the three Princesses show no interest in their powers. The Princesses then use their newly discovered powers to incapacitate her, and escape with Finn and Jake. Left alone with Ice King and covered in slime, she declares that she will make people know of her presence in Ooo.
In "Jelly Beans Have Power," Patience sends Princess Bubblegum a hand drawing of a circle with a cross inside, allowing her to tap into her innate elemental abilities. After Bubblegum uses these abilities to destroy her ice orb, Patience is seen viewing a vision board encompassing several of her targets throughout Ooo, including the princesses she had previously captured.
During the time Finn, BMO, and Jake have been away searching for the human islands, Patience has been able to finalize her plans to awaken the elemental's "true selves," using Betty as a magical battery. Her spell, however, causes their elemental power to overload their personalities, changing the physical make-up of Ooo and most of its inhabitants. This sends her into a deep depression ("Winter Light"), unable to fix what she has done, and lamenting that none of the other elementals brought shrimp plates to her party.
After a massively transformed Princess Bubblegum begins turning all of Ooo into candy, Patience decides to freeze herself in ice yet again, not wanting to stick around for the chaos she has unleashed ("Skyhooks II").
Patience's ice time capsule is briefly seen in the opening of "Come Along With Me," implying that she has survived for another millennium.
Patience is roughly Princess Bubblegum's height, but her body is curvier. Her hair is a dark navy, that's pulled back into a double bun. She has light blue lips and wears circular sunglasses. Her skin tone is the same grayish-blue as the Ice King's. She wears a dark pink-red button-up shirt, white pants, and black boots.
After her Mega-Spell, she transforms into a much larger version of herself. Whie she retains her blue skin tone and glasses, her lips turn a pure cyan and her hair turns white. She now wears a multi-layered off-the-shoulder gown whose straps display a blue, flame-like animation. The rest of her gown glitters, possibly related to her ice element.
When she emerges from her ice orb, Patience is energetic and jovial, speaking and moving erratically, especially enjoying ice puns. She quickly begins scheming, manipulating the Ice King and rallying the elemental princesses by force, and later kidnapping Betty to harness her power for herself. She repeatedly laments her "old age" (though she is only biologically 28). She is frequently portrayed as self-centered and condescending. Much like in her previous life as Urgence Evergreen ("Evergreen"), Patience shows a strong desire to survive at any cost, regardless of the fact that as an elemental, she would simply be reincarnated anyway.
As the Ice Elemental, Patience can create ice from her hands. She is able to create and control ice objects with ease, as shown when she made an ice chair and was able to make it spin around with just hand gesture. Patience is also capable of dispelling ice made by other wizards by shooting it with her own magic, as she does against Ice King.
Ice King states that her power is stronger than his own. Her ice's surface is also smoother, likely because as an elemental, she is the physical representation of ice and not just a user of its power.
- "Bespoken For" (flashback)
- "Skyhooks II"
- "Ketchup" (as Blue Tranch)
- "Come Along With Me" (cameo in the opening as an ice time capsule)
- Patience seems to have more control over her ice magic than the Ice King does, evident where she can freeze and thaw people and objects with precision, whereas Ice King cannot.
- Her name, Patience, parallels Urgence Evergreen's name. Also, despite the other elementals accepting their upcoming death, both Evergreen and Patience wanted to survive the cataclysm.
- While Urgence decided to race against time to stop the Catalyst Comet, Patience decided to freeze herself for years to avoid the Mushroom Bomb's devastation.
- Evergreen is a family of trees that do not change color from season to season. "ST" (shared tree) and "PIM" (protocol independent multicast) are both terms relating to "trees" in computer networking.
- In "Jelly Beans Have Power," she is seen wearing the same clothes as in the flashback from "Elemental," except with red lipstick.
- When Finn and Jake learn of Patience's involvement at the end of a very long story in "Bespoken For," Jake says, "All we needed was… a little patience."
- Patience's time capsule is briefly seen at the very start of the opening credits of "Come Along with Me."
- "Pim" is a Dutch diminutive of the name Willem, which ultimately originated from Wilhelm, with two elements composed as meaning: wil (desire) and helm (protection).
- The first two parts of her name "Patience St." are likly a pun on the idiom "Patience of a saint" meaning "A great deal of patience".
