[FairyKing]

I considered an alternate use of these colors and the mermaid and pegasus specifications, for a team focused on magic and "beautiful" mythical creatures (also ones stereotypical popular with girls), but the ideas I was coming up with for that felt like they belonged in Pretty Cure instead of Super Sentai. So instead I considered going for a mythical horse-and-rider theme, but then realized that real horses can't act much, so it would be better if the steeds could be played by suit actors. And from there, transforming bike-robots just seemed easier to make without looking creepy or ridiculous than horse-people. The post-apocalyptic setting was chosen to provide maximum excuses to film in quarries and other places that are good for bike action, and combining motorcycles and post-apocalypse make a biker aesthetic fit perfectly.
