Rainbow Dash
Published September 23, 2026
Rainbow Dash is the sky-blue, rainbow-maned pegasus who broke out as a fan favorite when Hasbro's My Little Pony: Friendship is Magic launched in 2010. Her cocky attitude and Sonic Rainboom stunt made her a mascot of the adult brony fandom, seeding a wave of YouTube AMVs and DeviantArt fan art that helped define early 2010s pony meme culture.
Overview
Rainbow Dash works as a meme through two overlapping tracks. The first is video, fan-made AMVs that pair her flight scenes and race sequences with punk, metal, or electronic music, a style codified by the earliest viral Rainbow Dash upload on YouTube1. The second is illustration, where the pegasus is redrawn constantly on DeviantArt as a tomboy pinup, an athletic showoff, or an over-the-top action hero3.
Her defining visual gag is the Sonic Rainboom, a supersonic dive that leaves a rainbow shockwave across the sky, invoked in fan writing as shorthand for maximum awesomeness2. The catchphrase '20% cooler' turned up as fan slang for anything a brony wanted to hype, right alongside loud Urban Dictionary tributes to her flying skills2.
