GHOST Attack Craft

Yes, that is a ship, a rather otherworldly craft, of which the design is based off of a creature (Specifically a creature I thought looked cool from Metroid Prime). It has the ability to travel through material by overloading itself with PPE (Pure Positive Energy), in of which it turns into a pure form of energy, allowing it to pass through material, much like gamma rays. Once the effect wears off, the ship returns to its normal state. As for locomotion, it projects a magnetic trail in front of it and has responding magnetic forces on it's body that slide into place betwixt the magnetic trails, sorta like a magnetic train that lays its tracks out in front of itself. Of course, the ship is a droid ship and has on-board AI, as a organic pilot would die when the ship phased into the positive energy spectrum...thingy. Done in MS Paint, and even though it looks simple, YOU try shading the blasted thing in MS Paint.
