One with them (Tsu'tey x oc male reader)

I do not own Avatar, or any of the images. I do change some of the story for it to fit an other POV, I realize there's a lot of dialogue so sorry if it's really long. Also there might be some sensitive parts, so TW; Blood/Gore, Trauma, and little bit 18+

Leo Sully, Jake and Tom Sully's little brother is a tough kid. He's smart, funny, kind, but will break your spine if you hurt his family. When he finds out his brother, Tom, passes he breaks down and is taken with his brother Jake to explore a planet named Pandora. How will he cope with this new life? Will he find love? Stay tuned to find out!
