Stompp is a kwami who is connected to the Ox Miraculous. With her power, its wearer can use the Miraculous to transform into an ox-themed superhero. She is currently dormant in her Miraculous in Master Wang Fu's jewelry box, as seen in "Sapotis".
Stompp is grayish blue with narrow black eyes. She also has nostrils, lighter grayish blue ox horns on her head, and a long and skinny tail with a thicker tip.
Not much is known about Stompp's personality except that she is persistent.
Stompp can fly, levitate, and phase through solid objects. She can also carry objects that are larger and/or heavier than herself.
As a kwami, Stompp is able to transform the holder of the Ox Miraculous into an ox-themed superhero, although it is unknown what the transformation looks like or what powers the transformed person gains.
Before Season 2
Before the Miraculous jewels were created, Stompp 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 the Miraculous was not being worn, Stompp was dormant in the Ox Miraculous, which was stored inside Wang Fu's Miraculous jewelry box.
As of season 2, Stompp has lain dormant in the Ox Miraculous.
In "Sandboy", Stompp was celebrating Nooroo's birthday in the Miraculous Box with the other kwamis, and was excited when Tikki and Plagg arrived. She marveled at the gift Tikki brought, thought it was a paintbrush, and played with the other kwamis. When it came the time to find Nooroo, Stompp got into position but in an effort to contact him, they contacted his wielder instead. Seeing this as their chance to find Nooroo, she encouraged the others to keep to singing. Hearing his voice, she shuddered at the thought of being his slave and prevented them from being discovered when they all cut off the connection. But then she realized if they contacted Nooroo's wielder, rather than Nooroo, then someone must have been akumatized, and the danger Tikki's and Plagg's wielders were in.
