Ice Colossus

The Ice Colossus (アイスコロッソス) is a replicated form of the Ice Titan. While in Kingdom Hearts Birth by Sleep, it appears alongside Hades in Aqua's story. Ice Colossus can also be fought at Mirage Arena in Kingdom Hearts Birth by Sleep. 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.

Story
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.

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 Colossus' legs until it falls over, stunned. Then, it is simply a matter of attacking Hades while dodging his fire attacks.
