The group takes the Rock Titan on in battle and proves to be victorious, strengthening their power of teamwork.

Kingdom Hearts II
The Rock Titan is one of the many monsters Hades tries to use to get rid of Hercules. When Sora, Donald, and Goofy enter the Coliseum, Hercules is shown throwing the Rock Titan out of the Coliseum.

Kingdom Hearts Re:coded
The Rock Titan is the one of the four sources of the bugs in Olympus Coliseum, and resides within the Keyhole, on Layer 15. Together, Data-Sora, Data-Hercules, and Data-Cloud are able to defeat him and keep advancing through the world.

Design
The Rock Titan is a gigantic, bulky creature that seems to be composed entirely of rough, uneven stone. His body is very large and barrel-shaped. His legs are short and its feet are flat, while his arms are relatively long and end in four-fingered hands. He has two comparatively small, draconian heads placed side-by-side on the top of his body. Both heads have thick necks, a peculiar lower jaw with four very large, blunt teeth. His eyes are very small and red, and the inside of both mouths are red as well.

The Rock Titan's name references his stony body, while "titan" is derived from the of Greek mythology, which were loosely represented by the Rock Titan and his companions in Hercules.

Kingdom Hearts
Lock-on to one of the Rock Titan's big feet and attack him with combos (such as Ars Arcanum and Graviga). When the Rock Titan falls on his back, use the Superglide ability to float to one of the heads and attack from the far side. Be careful though, as the heads will swing at Sora; Dodge Roll/jump to avoid damage. Beware of the shock waves it releases, a single foot-stomp can deplete more than half of Sora's HP. Make use of Aeroga and heal when necessary.

Alternatively, equip a powerful Keyblade—Lionheart, Oblivion, or Ultima Weapon—and repeatedly attack the legs with Ars Arcanum or Sonic Blade until he falls down. Then, just keep using Ars Arcanum on the heads, as it will deal a large amount of damage. Using this method, the only magic needed is Curaga. However, if Sora uses Aero, he will take damage simply by being close to him. Note each attack grants 1 tech Point.

Attacks
The Rock Titan has few attacks, which are not used very often. The first one consists of a ground attack in which he lifts his hands and pounds the ground releasing a large shockwave that can be easily evaded by jumping. The second attack, consists of the Titan lifting one of his feet and stomping it down.

The last and most powerful attack appears when he's knocked on the ground and Sora gets the chance to attack his heads; it slams the heads down in an attempt to knock Sora off.

Origin
The Rock Titan first appeared in Hercules as part of Hades' evil plot. When the planets align, it is the opportune time to summon the titans, supposedly. With Hercules' power, Hades destroys the prison in the ocean where the Rock Titan and company was and the titan climbs out of the ocean wreaking havoc on Greece. The titans head for Mount Olympus, where they attempt to get rid of Zeus. Hercules later comes to the rescue by using the Wind Titan to suck the titans up and send them flying into space.
