|“||Oh, to whom do I have the pleasure of speaking?||”|
Kaalki is currently dormant in her Miraculous within the Chinese Miracle Box, being kept by Marinette Dupain-Cheng. When the situation requires it, she temporarily becomes active to help Max Kanté transform into Pegasus.
Kaalki is 10 centimeters (or 4 inches) tall and is gray with a white mane, muzzle, arms, legs, and underbelly. She also has light green eyes, eyelashes, pointed horse ears with white insides, and a thick white tail that curves outwards.
Kaalki is very polite and speaks with proper grammar, although, she seems to be an elitist, given that she asked Max if he was someone glorious and famous. This suggests that she doesn't want just anyone to wield her Miraculous.
Kaalki can fly, levitate, and phase through solid objects. She can also carry objects that are larger and/or heavier than herself.
As a kwami, Kaalki is able to transform the holder of the Horse Miraculous into a horse-themed superhero, with the power of Voyage.
Kaalki and Ziggy are seen dancing together at the party that celebrates Nooroo's birthday in "Sandboy". After they broke their connection with Hawk Moth, Ziggy is seen attending to Kaalki, which shows that the two kwamis are possibly close friends, or simply get along with each other.
When Kaalki and Max met for the first time in "Startrain", he was friendly with her and only vaguely surprised at the sight of a kwami for the first time; but being that Kaalki was rather picky about holders, she immediately asked him if he was someone glorious and famous, only to stop when Ladybug assured her that Max was fit for the job. As of "Party Crasher", the two continue on working together in helping their allies against Hawk Moth.
Even though their interaction is brief, she listens to Ladybug's instructions without question seen in "Startrain". She even helped Marinette with her plan in rescuing Tikki and Plagg and cheered for her after the plan worked.
Before Season 2
When the concept of teleportation came into existence, Kaalki came into existence. Before the Miraculous jewels were created, Kaalki and the other kwamis traveled all over the universe unable to interact with humans. Then, thousands of years ago, a mage created the Miraculouses. When her Miraculous was not being worn, Kaalki was dormant in the Horse Miraculous, which was stored inside the Miracle Box.
During Season 2, Kaalki was dormant in the Horse Miraculous.
In "Sandboy", Kaalki was celebrating Nooroo's birthday in the Miracle Box with the others kwamis and she was excited when Tikki and Plagg arrived. She marveled at the gift Tikki brought, a marker, and she played with the other kwamis. When it came the time to find Nooroo, Kaalki got into position in an effort to contact him, but the kwamis contacted his wielder instead. Upon hearing his voice, she shuddered at the thought of being his slave, but they prevented him from discovering their location by cutting off the connection. They realized if they contacted Nooroo's wielder, rather than Nooroo, then someone must have been akumatized and that Tikki and Plagg's wielders were in danger. Kaalki instructed Tikki, Plagg, and Wayzz to find their owners.
In "Startrain", while Kaalki was dormant inside her Miraculous, she was temporarily given to Marinette by Master Fu, enabling her go on a school field trip to London and return to Paris if there was trouble while she was away. However, trouble didn't come to Paris but stowed away on a train causing Max's mother to be akumatized into the titular villain and blasting everyone into space. Needing to capture the Akuma and save everyone board the train at the same time, Kaalki was activated and introduced herself to her holder, Max Kanté, who transformed into the hero Pegasus. With her power of Voyage, the trio was able to stop Startrain and bring everyone back down to earth. Afterwards, Kaalki was returned to her Miraculous and Ladybug.
In "Kwamibuster", she was activated along with her kwami brothers and sisters to help Multimouse enact her plan of rescuing Tikki and Plagg. During the confrontation, Kaalki was one of the few kwamis captured but was set free with the help of Multicat. After Kwamibuster's defeat, Kaalki and others cheered for Marinette as their plan was a success and was returned to Miracle Box.
In "Miracle Queen", Kaalki was activated by a possessed Max transforming him into Pegasus and her powers were used against the heroes until they managed to deakumatize the titular villain. After Hawk Moth and Mayura fled and the role of guardian was passed to Ladybug, Kaalki and her Miraculous were retrieved and returned to the Miracle Box.
