As you enter Hercules’ world, again you see that you are alone, and your only companions are the Heartless that want nothing more than to make a pair of Riku-skin boots. After you gain the Key of Beginnings Card, your next objective is to use it on the crown door. The maps are getting slightly larger, meaning you will be able to create different kinds of rooms if you wish.
Make your way to the last door and use the Key of Beginnings to proceed to the next boss battle.
Boss Battle: Hades
The great thing about Riku is that he is all about the offensive, which makes these boss battles seem like a breeze. While Hades’ moves like Firagaball (where he throws fireballs) and Temper Flare (in which he follows you with flames shooting from his hands) may be obnoxious, they are very easy to break or dodge with Riku. Dodging and getting behind Hades to combo him up is a simple way to cause a lot of damage.
Just like all the previous fights, entering D Mode and using Dark Break and Dark Firaga are great ways to bring on the pain.
Staying on the offensive causes major damage to Hades as well as creates more opportunities to enter D Mode, which causes heavy damage.
At the end of the fight, Riku levels up and gains the Hades Card. After the fight, like always, the only thing left to do is leave Olympus Coliseum, by heading through the north-most room, and return to Castle Oblivion.
In the following scene, Naminé is seated when Larxene comes in and begins taunting her about what she has to do to Sora. You will see the effects of Vexen’s scientific prowess as Riku Replica enters and talks to Naminé as if he knows her. It seems Naminé has some amazing powers. Riku Replica pulls out the same charm that Sora carries and tells Naminé that he will protect her from whatever is hurting her. After the scene it is time for the real Riku to head to Halloween Town.
