Ketuwong is the Na'vi word for: alien.
If you look at the body and face, you see Ketuwong looks like Ben.
Home Planet: Pandora (it's actually a moon of Polyphemus).
Height: 3 meters ~ 10 feet
Skin: Striped blue with bioluminescent spots
He's high, so he can reach higher objects
He is an excellent climber
He knows the na'vi language
His bones contain carbon fiber, so it's harder to break them.
He can use his queue on other creatures with a queue to create "Tsaheylu", the bond.
The Na'vi are aliens after all, so they should be in the ultimatrix.
