Walkthrough:Kingdom Hearts/Olympus Coliseum
Olympus Coliseum
This is an optinal world, but we recomend coming here, as it's known to be one of the best worlds to train. There is no party member in this world.
Upon entering the Coliseum, you'll notice a strange looking Satyr attending to something. Talk to him, and the Satyr will ask you to move a nearby block of stone. However, it is far to heavy. After you attempt to push it, talk to the Satyr again, where he'll finally show his face and relise his mistake.
The Satyr, Philoctetes (better known as Phil), will then put Sora on a test involving barrels. Complete the barrel rounds within the time limit and you'll obtain Thunder (or an upgrade if you have already completed Atlantica). This mini-game is not very easy to complete, as some barrels are out of reach, and require timing to destroy (or Glide from Neverland).
However, Phil is not impressed with Sora's skills, forbidding him from entering the games. As you leave the building, a strange blue man will hand Sora a pass, which will allow him to enter the games. Head back inside, and get ready for the games.
Fight your way throgh the rounds and in the final round, you'll find yourself fighting a mysterious warrior who's working for Hades. It does not matter if you lose, but it's better to win this battle if you want bonus EXP.
After this battle, a large three-headed dog, known as Cerberus will appear and attack the warrior, Cloud. However, another man, Hercules, will appear and fight Cerberus as the party escapes.
Through your team will be too weak at this point, to complete this world, you need to defeat Cerberus. You'll have a larger chance if you have already defeated Clayton (as he rewards the player with Cure). Once you are ready, enter the arena.
After defeating Cerberus, Phil and Herc will dub the party as Junior Heros, and the Cups will be unlocked over time.
