Show Pony is the assistant of Dr. Death Defying, known for wearing obnoxious polka-dot patterns. They are played by independent pop artist and producer Ricky Rebel.
Show Pony is usually portrayed wearing a blue helmet with large white polka dots and an orange visor, a white crop top with the word 'NOISE' printed on the front in black and a black shirt underneath (possible chest binder), white leggings with slightly smaller blue polka dots, a leather cord bracelet on their right wrist, a white band around their right upper bicep, white mesh fingerless gloves, a key on a cord around their neck, and roller skates.
They appear in the True Lives of the Fabulous Killjoys comic (for a single panel) in the year 2039 and in the "Na Na Na" and "SING" music videos released by the rock band My Chemical Romance that takes place futuristically in 2019 (filmed in 2010).
Show Pony was seen in the beginning of the Na Na Na video, delivering a vinyl to Dr. Death Defying. The SURVEILLANCE VIDEO 1D showed Show Pony rollerskating, probably before the beginning of the Na Na Na video.
Show Pony was last seen at the end of the SING video, helping The Girl into the van with Dr. Death Defying in Battery City, at BL/ind's facility. Show Pony doesn't have an active role in the story of the Killjoys comic, though they appear in the girl's flashback of the events of the SING video in Issue 2 and in the background of a group photo of Show Pony, Dr. Death Defying, and DJ Cherri Cola owned by Dr. Death Defying in Issue 4.
- Show Pony is often interpreted to have a nonbinary gender by fans. It has also been speculated that the black half-shirt underneath the crop top is a binder.
- Show Pony was also referred to as “Dr. D’s robot friend” by Gerard at a convention meeting. However, nobody is sure of the validity of this claim, and most do not accept it as canon material.
- Fans once called Show Pony "Ladyboy" before knowing their official name, as that was the given name on the casting call sheet.  However, Gerard confirmed their name as Show Pony on Twitter.
- "SHOW PONY" can be found written across their knuckles at the beginning of the "Na Na Na" music video.
