Kai Zephyr

He's far more friendly to strangers and is quite adventerous. He does get whiny whenever his twin purposely ignores him. He absolutely adores affection and doesn't hide this even with strangers, much to Fei's dismay. It wasn't until a kidnapping incident did he learn to not be so clingy to people outside of family. It was then did Allura begin to teach them how to fight. Kai was like Allura, he was excellent at ranged combat.
