The X-5000: The red in the center is a laser web on the inside. The little ship is a lookout ship called the T-8000. At the top is a navigator. Without it you'd be lost in space forever. The little rectangular hole near the bottom is where the lookout ship comes out of.
Toa Twohawka: Beside him is a flying surf board. When he smashes his two swords together, they shoot fire. The top of the swords can be used to pinch.
Tworaga: His hands are spikey so that he can use them as weapons to attack victims. He has very spikey teeth so that he can bite other bionicles, which makes them obey his commands.
