Final Chaos

This is Sky Kan's ultimate weapon. If you see this you know he's angry, Takes quite a bit of energy to summon and as such Sky mostly doesn't use it but when he does it has consequences. Caused by the coming together of the 'true' Chaos blade and the 'true' soul of chaos, it is a fast powerful weapon that can discharge energy. The most gruesom combo Sky uses with it is half impaling the body and shooting multiple energy blasts directly to the heart. Only one person survived this, but after the battle Sky said 'he may have survived it once, but no one can survive it twice'. It is said that Sky used this sword to protect Sea Fuukai from Tiamat and Bahamut when they attacked her, despite how worn out he was, after the battle was concluded and both creatures had been slain, he collapsed with severe internal and external lacerations due to overuse of energy and powers. Sea (yet again) took him to be healed. The motivations for the two creatures to attack Sea are still unknown.
