Omegas:
Kai
Pixal
Skylor
Kai hates being a male omega. He is always being flirted with no matter where he goes and he has learnt to defend himself thanks to Lloyd's uncle Sensei Wu owner of the tea shop where he works. Sadly though there is always Morro who cannot take a hint saying Kai would be the perfect omega for him because he needs a strong alpha to protect him and that he's so rare and pretty. The thing is Morro just likes him for his looks and that he would be a way to be more powerful in Ninjago city since he had the only prime male omega as his mate.
Kai can't resist his instincts forever though and they drift too three polyamorous multi-coloured teenagers who see him as more than a pretty doll to flaunt. Morro isn't going to give his omega up that easily though.
