Stunt Cat
This emoji is a non-RGI proprietary ZWJ Sequence. It has not been recommended by Unicode, meaning it will most likely appear as its component emojis across most platforms.
A variation of Ninja Cat which was shown with a helmet and cape. This emoji was included in Windows 10 as a proprietary ZWJ Sequence which was not supported by other vendors.
Variations included the canonical ๐ฑโ๐ค Ninja Cat as well as ๐ฑโ๐ Astro Cat, ๐ฑโ๐ Dino Cat, ๐ฑโ๐ป Hacker Cat and ๐ฑโ๐ Hipster Cat.
Stunt Cat and the other variations of ๐ฑโ๐ค Ninja Cat were removed in Microsoft's Fluent emoji redesign, released in late 2021.
The Stunt Cat emoji is a ZWJ sequence combining ๐ฑ Cat Face, Zero Width Joiner and ๐๏ธ Motorcycle. These display as a single emoji on supported platforms.
