Blue Streak is Invader Myu's voot cruiser. Myu got it from Anj because whenever Anj took her somewhere (usually to an Invader conference), they were late. Blue Streak has Myu's personality, which makes it sometimes drive itself and endanger the rider. Nio tried to steal it and reverse engineer it once, but because Blue Streak was sort of Myu, it put up a fight and smacked him across the planet.
It looks like Zim's ship, only blue.
