"And let us not forget Neytiri's father Eytukan. That would also be a possible name and I mean come on, Jake couldn't say no to that because he kind of was indirectly responsible for his death."

"They could also use middle names to honor their friends and relatives.

Possible names for boys would be: Tommy Tsu'tey Sully, Eytucan Tsu'tey Sully, or Tsu'tey Tommy Sully

Possible names for girls would be: Sylwanin Grace Sully, Trudy Sylwanin Sully, or Grace Sylwanin Sully

Unless Jake and Neytiri decide to have 6 children. Then they would have enough for Tommy, Tsu'tey, Eytucan, Sylwanin, Grace, and Trudy Sully. Pandora's Brady Bunch!"

"Actually, I took another look at the script and found out that Neytiri's full name is Neytiri te Ckaha Mo'at' ite. Sounds like Ckaha qualifies as a middle name but....whatever. I just know that my theory about the sibling's names should be correct. However, there's no telling how many children they will have. Probably Eywa will bless them with high fertility. We'll just have to wait and see."

"Hey, good question, because at the end of the script we find out Neytiri is already pregnant, so we know the sequels will have little Jake's or Neytiri's."

"First of all, we have to assume that Jake's avatar is capable of reproduction and there aren't more genealogical differences than five fingers vs. four fingers (by the way, has anyone taken a look at Na'vi feet?) which might prevent a viable offspring..."

"Great points, victoryblade. I just want to point out that the script shows Neytiri pregnant near the last scene. I guess they decided to change that for unknown reasons. But I would think JC will write children in the sequel for them if he wrote that about her in the 1st movie."

"It will be interesting to see what happens with the development of the 5 fingered hand vs the 4 fingered hand. 5 fingers makes it possible to hold much heavier things like weapons. When Jake punches Tsu'tey, he takes him down because of the size of his hand. I bet the Na'vi don't do that kind of fighting because their hands are so slim.

Will this get developed in the sequal? One of the reasons Jake is brought to the Na'vi by Eywa is because they need more power and punch. As the film ends you can see that his physical body his much more muscular than Tsu'tey's. This is the physical legacy he brings to his children."
