Here I will do my best to answer any questions that you might have on this Fanfic. I will not include Jake or Neytiri, because we all know them very well, atleast I would hope so.
Mike- Supreme Commander of the Spartan Empire. Considered to be a living god among his friends and allies, but considered a Demon among his enemies. Mike never backs down from a fight he knows he can win. Sometimes his anger gets the best of him, but thanks to his closest friends, they can calm him very quickly. He is loyal to his friends and loved ones. If one is threatened, he won't think twice about helping them. His body was burned from an Ion Cannon strike on the planet of Eur, he saved millions of his spartan's lives, but lost much in the process. He has overcame everything that life threw at him. He wants to start a family, but doesn't love any of his spartans enough to choose any of them.
General RAAM- A veteran of countless wars. He met Mike when they were old enough to remember one another, and from that day on they trained together and rose threw the ranks. He introduced Mike to Jake Sully. RAAM's unnatural strength is only beaten by Mike's. He is ruthless to his enemies, but is like a brother to his friends. He is thought the be the only one that can calm Mike when he gets into one of his 'anger fits'. He would gladly kill millions if it meant the expansion of the empire. His skin is pale white due too a birth defect, he uses this as a weapon. He is feared among his enemies, his own allies fear him. He favors a sword that he had forged, and a Desert Eagle, but will carry the standard issue chaingun if the situation called for it. He protects Mike as if he was his own brother.
Rai'uk- A highly skilled Na'vi warrior. Member of the Ikran People of the Eastern Sea. He hates the Sky people, as they killed many of his friends and family. He frequently ignores the orders of the Olo'ektan, or clan leader, thinking he knows how to deal with things. He tries to convince many of the women of the clan to be his mate, He is mostly focused on Krystal.
Krystal- The next in line to be Olo'ektan of the Ikran People of the Eastern Sea. She is considered of the most beautiful woman in the clan. Her skill as a hunter is matched by her skill as a warrior. She dislikes Rai'uk for his blindness and disregard of their clans wishes. She wants him banished, but her father ignores her. She has one of the two Crimson omens, which protected her during the first war for Pandora. She trusts very few sky people, even they must watch their words around her.
Tasun- Current Olo'ektan of the Ikran People of the Eastern Sea. He is the most skilled warrior within the clan. He has three children. A son, who was killed during the war, and two daughters. One daughter is mated to another Olo'ektan of another clan. Krystal being the youngest, and only one without a mate. He wants to forgive the Sky people, in hopes they will listen next time around. His mate is Kyuna.
Kyuna- Tsahik of the Ikran People of the Eastern Sea. Her trust in the sky people is questioned by her clan mates. She believes that they can be forgiven and they can learn. She loves her children with all of her heart, she will go as far as killing the person who hurt them. She is very close to Eywa, the goddess gave her the second Crimson Omen to give to her child that goes the longest without a mate, that being Krystal. She is highly respected among the Na'vi. Her mate is Tasun.
