This one is interesting and can be quite optional if you wish to continue the game. But it has a great story either way...
You walk through the gates and are in awe with what is going on.
You will talk to Phil... he's a funny creature and he really has a mouth xD
Phil: He runs the coliseum... at first, he assumes that you are Heracles but you just make sure to let him know you are not.
Now... talk to him about playing the world. But you need a pass so just go out towards the gates.
You get to meet Hades... his sort of my favorite villain but yea... Hades will give Sora a pass so you can get into the games.
Hades.
He does get funnier through out the series but for now, let's just talk about what he gives you...
A pass. But remember, you already went through a trial busting barrels... this is not the battles that you get to do in this world.
However, the battles are not random so you can figure out what they are if you need a walkthrough... I had to look those up xD
After the first battle, you get see Cloud.
Cloud:
He is a Final Fantasy character but he looks completely different here. After a few battles, you do get to fight Cloud as a boss in this world. Also, this battle is win or lose type of thing... it leads into a cutscene.
Just to know... Hades may be my favorite villain, he can be a butthole too. Because now you have to beat a Cerberus... which a three headed dog like creature.
Cerberus:
Keep in mind... this boss is an ass to beat. It took me a while to beat him... just beating him up and avoid all attacks if possible.
You get to meet Heracles too during this scene too.
Heracles:
After beating this boss finally. You learn that you are welcome to participate in the games anytime as you are junior heroes... some reason, I think this part always foretold what is ahead of your gaming xD
Anyway, Herc says that in order to become true heroes, you have to experience a lot... so you do get to go back to this world several times.
As you head out, you get to talk to Cloud who talks about darkness... kind of weird for a Final Fantasy character xD Sora says he is searching for his light too... so... yea, this is awesome to see.
After Sora leaves, you see Hades talking to himself... then boom... we get a character that is not of this world.
Maleficent:
I will tell her story another time because she plays a big role in all of these games... you'll see ;)
You will be back to this world later on but with other stuff in mind.
Hint: I suggest waiting until after you complete some worlds and see the pop up with the chipmunks... but wait until you are stronger because you get through a whole lot with this world.
I will mention the specials later on... for now, we are just here for the story...
Now it's time to go...
But where to next? Who knows.
