Since many people seem to not know many of the characters in FF XII that have been revealed, I have decided to compile them and their info here.
Ashe- the Princess of Dalmasca. Her whole family was killed in the invasion of Archadia, including his father (the King) and her husband, Rassler. Now she runs a resistance against Archadia with the help of Vossler. Her real name is Amalia.
Baga'mnan- a green bangaa who is mysteriously tracking down Balthier for an unknown reason.
Balthier- a Sky Pirate who commands the airship, Strahl. His partner is a viera named Fran.
Basch- one of the best knights of Dalmasca. He was presumed to kill the King of Dalmasca, and Basch is friends with Vossler. (two years ago before the game starts)
Belga- one of the Judges who have great power in Ivalice.
Cid- Cid in this game seems to be an engineer of airships too. Not much information about him is known yet.
Dreis- one of the Judges who have great power in Ivalice. The only Judge who is a woman.
Duke Ondoll- the guard of the doors to the air city of Bhujerba. An agreement with the high leaders of the Empire, Duke Ondoll brings its support to the rebellious forces of Ivalice.
Fran- Balthier's partner who is a viera. She is a master of weapons.
Gabranth- one of the Judges who hold great power in Ivalice. Gabranth seems to be the leader of the Judges.
Ghis- one of the Judges who hold great power in Ivalice.
Gramis- the emperor of Archadia. He is also the father of Vayne and Larsa.
King of Dalmasca- the king of Dalmasca and the father of Ashe. He seems to have sold Dalmasca to Archadia, and was killed in the invasion. People assume that Basch killed the king.
Larsa- one of Gramis's sons. He is quite young, and he seeks to find a certain Nethicite stone. He uses a fake name called Ramon.
Migelo- a gentle Bangaa who runs a shop. (not so sure) He seems to take care of Vaan and Penelo.
MontBlanc- an intelligent moogle engineer who is the brother of Nono.
Nono- an intelligent moogle engineer of airships who is the brother of MontBlanc.
Penelo- Vaan's close friend (or maybe girl friend?) who is also an orphan. She seems to have great dancing skills, and is a gentle person.
Rassler- the husband of Ashe who is presumed to have died during the invasion of Archadia.
Reks- Vaan's brother who is a Dalmascan knight. He also was presumed to have died during the invasion by the hands of Basch. (but not proven true yet)
The Senate- a group of people who seem to have power in Ivalice. Not much information is known about them yet.
Vaan- a young lad who dreams to be a Sky Pirate. Penelo is his close friend (or girl friend) and they are both orphans under the care of Migelo.
Vayne- the older brother of Larsa, and is one of the sons of the Emperor Gramis. He looks like a villain, but is said to lack arrogance.
Vossler- one of Dalmasca's best knights. He is friends with Basch before it was presumed that Basch killed the King, and is now part of Ashe's resistance. He also was seen wearing black armor, and he might be a 6th Judge. (rumor)
Zargabaas- one of the Judges who hold great power in Ivalice.
Feel free to comment or suggest about things that I can add. And if I did mistakes, just point them out. Hope this helps.
EDIT: I've added Baga'mnan and applied the corrections pointed out by Vivisteiner. (Thanks!) I also added the King of Dalmasca.
[EDIT 2:[/b] Added rumors about Vossler and the new character info about Cid and Duke Ondoll.
