The Ice Titan is a resident of Olympus Coliseum, and one of the powerful Titans who serve Hades. It was an antagonist in the animated film Hercules, where it was named "Hydros". It appears as a boss in the North American, PAL, and Final Mix versions of Kingdom Hearts, as well as in Kingdom Hearts Re:coded.
 Kingdom Hearts
Following Sora's completion of the Hades Cup, the Ice Titan appears in Olympus Coliseum as the sole contender in the Gold Match. Sora enters the Gold Match alone and finds the colossal, ferocious giant of ice awaiting him inside the dim, darkened Coliseum. Sora takes the Ice Titan on in battle and proves to be victorious, earning the Diamond Dust Keychain for his troubles.

The Ice Titan is the last of the four sources of the bugs in Olympus Coliseum, and resides deep within the Keyhole, on Layer 30. Together, Data-Sora, Hercules, and Cloud are able to defeat it and fix the world's code.
The Ice Titan is a gigantic, emaciated, humanoid being that is, true to its name, composed entirely of ice. It has fairly long arms that end in clawed, four-fingered hands. Its icy ribcage is always visible, and its upper back is lined by tall spikes. Its head is rather small in comparison to the rest of its body. Its blocky mouth is filled with sharp teeth, and its eyes are small and barely visible. It has a spiky crest decorating the back of its head and cheeks. Its upper legs are very thin, while its thicker lower legs are frozen to the ground, forcing the Ice Titan to constantly break and regenerate them to walk. The Ice Titan is actually a very small being of ice, not even reaching Sora's knee, but it is able to grow very large in order to tower over its opponents.
The Ice Titan's name references its frozen body, while "titan" is derived from the Titans of Greek mythology, which were loosely represented by the Ice Titan and its companions in Hercules.

The player should set Firaga and Curaga to his shortcuts. However, using any form of Aero magic causes the Ice Titan to simply use larger icicles which cannot be deflected, negating the benefit of Aero and removing the main method of damaging the Ice Titan.
The Ice Titan's primary method of attack is firing ice shards at Sora. Deflecting these ice shards back at the Ice Titan by using Guard is also the key to defeating the Ice Titan. Each time Sora deflects an ice shard, he is rewarded with 24 Tech Points (120 in Final Mix, with all Tech Ups equipped), and once the Ice Titan has been hit with enough ice shards, he falls to his knees for a short period, making him vulnerable to air combos and Ragnarok. However, the Ice Titan expels a flurry of ice shards when he stands back up. The Ice Titan can also be damaged with Fire spells or Strike Raid. However, Fire spells take longer to hit than the deflected ice shards, while Strike Raid deals less damage and forces Sora to stand still, making him highly vulnerable to the Ice Titan's attacks. It is also possible to jump on the Ice Titan's hand when he strikes the ground, then ride it up to his head and land a few air combos before falling back to the ground.
The Ice Titan can also attack by summoning shards of ice from the ground, conjuring snowballs to fall on top of Sora, creating an icy mist to freeze Sora in place, and performing a technique that freezes Sora. Most of these moves can be avoided simply by constantly moving. The Ice Titan can also create patches of slick ice on the ground which will trip Sora, preventing him from attacking but making him temporarily unable to be hit. Sora should stay close to the corners when the Ice Titan angrily lifts his hands in the air, which only happens while the Ice Titan is on his yellow and green HP ranges. This allows Sora to dodge two of the Ice Titan's freezing techniques.

The Ice Titan first appeared in Hercules as part of Hades' evil plan. Supposedly, when the planets align, it is the perfect time to summon the titans, so Hades "borrowed" Hercules' powers to free them. The Ice Titan headed for Mount Olympus while freezing the land. At Mount Olympus, the Ice Titan cooled the Fire Titan's magma to make a shell surrounding Zeus. However, Hercules later came to the rescue with his powers back, and sucked the Ice Titan and company up with the Wind Titan and sent them flying into space.
