Ice Colossus

The Ice Colossus, misspelled as "Ice Colussus" in the Japanese release, is a replicated form of the Ice Titan. It debuts in Kingdom Hearts Birth by Sleep, appearing alongside Hades in Aqua's story. Ice Colossus can also be fought at Mirage Arena in Kingdom Hearts Birth by Sleep.

Design
The Ice Colossus is a massive, 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, 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 Colossus to constantly break and regenerate them to walk.

The Ice Colossus's name refers to its frozen body, while "colossus" is a descriptive term for anything of gigantic size.

Kingdom Hearts Birth by Sleep
After Hades challenges Aqua to a fight, he reveals his trump card: the Ice Colossus. Hades claims that the rules state that fights do not have to be just one-on-one, and that she can pick someone to assist her as well. Zack volunteers to help but Aqua says she can handle it. She fights Hades and the Ice Colossus two-on-one, and emerges victorious. After the battle, Hades remarks that the fake was not good enough, revealing the Ice Colossus to be an inferior copy of the actual Ice Titan.

Strategy
The Ice Colossus is a much easier opponent than the Ice Titan. It mainly assists Hades by bombarding Aqua with ice shards which do little damage on their own, but together can kill Aqua easily if her HP is low. Unlike with the Ice Titan, the ice shards cannot be deflected back at it. It also attacks by punching the ground and creating a shockwave and also can breathe ice breath. Simply dodge its attacks and attack the Ice Colossus's legs until it falls over, stunned. Be careful though, it creates shockwaves when it stomps that can damage the player. Then, it is simply a matter of attacking Hades while dodging his fire attacks.

A Time To Chill
The Ice Colossus returns as an optional boss in the A Time To Chill round of the Mirage Arena, fought after several waves of Unversed and Zack and Hades have been defeated. The fight will flow similarly to the fight fought in the Olympus Coliseum, albeit the only change is the boss's greatly increased HP and Hades no longer fights with it. The player should be at a high level and have a strong Keyblade in order to ensure maximum damage is dealt to the boss. The fight should be easy as long as the player remembers each character's strengths and weaknesses.
