Skyblast is half toa and half sky engine.
The wings and the winged tail thing are taken from the hero factory drop ship.
Skyblast used to be a normal Toa of energie and a great weapon smith, he used his energie to power is guns and whatever invention he created. He also had a speacial way of using this energie, he could transfer some of it to other Toa's in battle therefor boosting them, making them faster, better, stronger. He was much more of a support Toa. He was giving a test run to his new invention flying machine capable of going to the speed of sound, He went to see an annomaly in the sky, a huge weirdly colored cloud...Little did he know that it would change him forever, It changed him, fusing him to his machine and increasing his speed and is strenght. It also altered his energie powers, he could generate an aura around him boosting every Toa that fights along side of him.
