Characters: Here are the characters known to be part of the movie. Feel free to use the avatars I made but please don't claim that you made those!

Cloud Strife

He is still the main character. From what I see he seems depressed from everything that has happened over the two years. Though there has been a good chance that Cloud could've lived with Tifa, this doesn't happen (T_T). Cloud lives alone and calls the church where he met Aeris his home I think(>_<). Tifa and Cloud however takes care of the children in the orphanage and runs a service called "Strife Delivery Service" as a job. The plot thickens as a call for work from a man named Kadaj takes place...


Tifa Lockhart

She runs the 7th Heaven Bar once again and takes care of the orphans. Tifa seems to be just a companion to Cloud in the movie (T_T) although we cannot really be sure but I think Tifa has accepted the fact that Cloud still hasn't gotten over the death of Aeris (>__<!!) and this maybe the only way Cloud will see her, as a very good friend..( Although I'm hoping there is a possibility they'd be together, I feel the ending would point to cloud dying or something. It would really relieve me  if it'd be related to Tifa [Cloud move on!! T_T] Read on more on the ending theories).


Vincent Valentine

Vincent seems to act as Cloud's older brother hehe anyways Vincent has more knowledge of the situation as he travels the world. He knows about the illness and the plans of Kadaj and the other two guys I think. There was a game concerning Vincent (Dirge of Cerberus) which takes place sometime before the plot in AC.


Zack

I think Zack will only appear in the game as a flashback. A scene reminding Cloud when they were in the truck trying to escape from Shinra. (I must say he looks really cool there, a bishy *__*)


Aeris

Again I think Aeris will not appear in the game in the flesh rather her appearance would serve as flashbacks or perhaps a way of communication with Cloud since there was a scene when Cloud and Aeris were talking back to back seemingly like  a dream.


Sephiroth

Aha, the ever favorite villain of all times has returned. For the first trailers he seemed to appear as a memory but nonetheless we see him in action! One of the trailers show Sephiroth thrusting with his sword leaving the words "I will not become a memory". So I guess that concludes that he will return ahahahaha.


Marlene Wallace

The girl we all know Barret has been taking care of seems to play a good role in the movie. She seems to be a good friend with Denzel. As one of the children she will be abducted by the three silver haired man to complete their plans.



Yuffie, Cid, Barret, Red XIII


The old crew of the game comes back too although not much details are known it would seem like they will only play a role during a fight scene or invasion in the city [as of the trailer]. I think Caith Sith might not make an appearance since it would seem odd basing it on the theme of the story. It would seem inappropriate seeing a cat mascot taking in consideration the dark and serious atmosphere of the movie. I'm not really100%  sure though, just an opinion.



Kadaj, Yazoo and Loz


Kadaj seems to be acting the leader of the group although he seems to be the youngest among the three. The three men looks like Sephiroth's brothers or something and it seems they hold a striking link to him  that it seems they want the revival of Jenovah or Sephiroth himself for a reason not verified yet perhaps continuing just as what Jenovah has been planning to...?


Denzel

I don't really know who he is but maybe he's an  orphan Tifa has been taking care of. I think he is affected greatly with the disease that the previous three mentioned wants him along with the other children.



Reno and Rude


I don't know much what would be the role of the Turks here but I think they are on Cloud's side.


Wheelchair guy

At first I thought it was sephiroth but when I saw the trailer I confirmed it wasn't really him so maybe this can only be President Shinra. The guy has a beard and is old so it only points to him hehe
