From the notes of Jedi Master Rekkan Thrace:

Potential Candidate #4:
Name: Danzan-rav Jaa
Species: Kajain'sa'Nikto
Homeworld: Kintan
Mannerisms:
Jaa's father was a Hutt's skiffguard, so Jaa enjoys spinning around large sticks and attacking trees with them. His parents, Kha’ta and Sain-shand Jaa, taught him to have a brave face. This created a permanent slight smile instead of the usual expressionless Nikto mouth. He is very serious. I think. It's hard to tell because of his smile. He is also the first one to rush into any challenge, but only if he sees a good reason to.

Background:
Jaa is a Red Nikto, born on Kintan. His parents saw his force potential and fought to escape from the Hutts and their planet. They got as far as Ryloth and put him in the hands of a Twi’lek family who contacted the Jedi on their behalf as they fled (into hiding or to their deaths; no one knows). Jaa was raised to hate the Hutts and any enslaving races. He has pity for any enslaved races and tries to help them (even as a child in the small ways that a child can). He wants to become a Jedi and fight for the freedom of planets enslaved by the Hutts.

End slavery

Bravery:
Jaa is always ready for a fight if it means defending those enslaved by tyranny. He rushes to be the first into scraps with other children who seem to be oppressing others.

Anger:
His well-meaning attempts to liberate others often mean he pushes himself too far emotionally and anger takes over.

Has a permanent smile that looks out-of-place when he's fighting, meditating, or...well...doing anything really.
