well on the first part of number 2 but realy no not unless you have a cheat code device
You get to play as Terra, Ventus{Roxas}, and Aqua.
you can't play a s Roxas.
u play as roxas in the beginning of kingdom hearts 2 but then he dissapears so u have 2 play as sora from then on
no, not without modifying your game. you can only play as Roxas in the beginning of Kingdom Hearts 2. if you want your fill of more Roxas then i recommend buying Kingdom Hearts 358/2 days. you play as Roxas through the whole game!
roxas's theme
*SPOILERS* After xion dies, you can play as duel wield roxas who wields oblivion and oathkeeper
Well, you can't reallybecome Roxas, because you only play him once in the entire game. You play as Roxas for the entire first part of the game, which is also the part where he is in the fake Twilight Town. But eventually he has to give his heart or his half or something to Sora so Sora can save the world...again. There will be many other references to Roxas during the rest of the game, and you will encounter him once or twice, but no, you cannot become Roxas after your character has been switched to Sora.
In the beginning of KH2, you ARE Roxas. You play as him for a while before Sora finally awakens and then you don't get to play as him again. There could be a cheat for it, though... Try a website I think is the right one: CheatCC.com I think that's the web address. If not, then sorry!
As far as i know you they aren't in it like you can play with them. But there are few scences where you do at least see them. And for Ven the character who looks like roxas it is said he does have some connection to sora and roxas
At the point in the game where you get to "the world that never was." When you get to the Skyscraper with Donald and goofy, sora will apear with roxas and they will fight, but YOU yourself do not get to fight roxas. Its all in story mode, so you can either watch it or skip it, but not play it.
you can, but only for the opening part of the game
You can only play as Data-Sora in Re:coded.
