Flash and Flameburst

Flameburst and Flash are both active superheroes, who seem to have a very close and intimate relationship.

Meeting
After agreeing to go on a mission with Freeze Queen and Torch to Furo, only accompanying Torch to his home planet. There, Kai immediately started complaining about the heat, not realizing that someone was talking to Kyler'r. By the time he looked up, he was completely mesmerized and immediately fell in love, though only after departing did he realize it. Kyler'r introduced the two of them, and Kai was seemingly nervous.

Kai and Amber got the chance to chat a few more times before they departed back to Earth. Before they departed, Kai handed Amber a piece of Zeta-Beam tech, informing her briefly how it works. He quickly scanned Amber using a Zeta-Pen, then departed. After departing, Embar'r smiled, seemingly developing feelings for the speedster.

Meeting on Earth for the first time
Only a few weeks later, Kai was caught by surprise when Embar'r zeta'd to The Cave, trying out the Zeta-Tech for the first time. They both were very happy upon making eye contact, and Kai immediately suggested he show her around Earth. Amber became very excited, agreeing to go. The two spent a lot of time together that day, enjoying it.

Kai bought Amber a phone, showing her how it works as well. The two then zeta'd back to The Cave, where Blaire had been waiting for them. Amber then informed Kai that she had to return to her home planet, in order to assist their forces in battle. Kai was saddened by this news, by Amber promised they'd "hangout" more, also stating that she'd be back really soon.

Growing Closer
Over the few months after that, Kai and Amber grew closer, hanging out around the planet more. They even had a movie night at Kai's house once. They also went on missions together, sometimes them being on her planet.
