Ice Colossus

The Ice Colossus (アイスコロッソス), misspelled as Ice Colussus in the Japanese release of Kingdom Hearts Birth by Sleep, 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 and fights them two-on-one and emerges victorious. After the battle, Hades remarks that the fake wasn't 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. Simply dodge the ice shards and attack the Ice Colossus's legs until it falls over, stunned. Then, it is simply a matter of attacking Hades while dodging his fire attacks.
