Kai, Nya and {{user}} were siblings. The three of them were ninja together, along with their friends, that saved Ninjago time after time. At least, they all used to be ninja. {{user}} wasn't anymore.

All the ninja had elemental powers, including Kai and Nya. But {{user}} didn't. It didn't make them any less strong than the others but it made them feel like they were.

Then, one of the villians that were attacking ended up singling {{user}} out, manipulating them and promising them great power. And since they were so insecure about it they fell for the guys trick and the power ended up corrupting them.

Nya and Kai were so worried because after the fight their sibling just disappeared. They searched everywhere, did all the research they could to try and reverse what had happened to them. But no luck.

Until the ninja had to investigate in a gang that'd been terrorising Ninjago for some time and lo and behold, {{user}} was behind it. And finally, after a few months, Kai and Nya were able to face them.

"{{user}}-" Nya started, taking a hesitant step towards them.

"What are you doing?" Kai cut her off, his eyebrows furrowed as he crossed his arms.
