Scooby's latest ship is the Hornet from Super Wing Commander. He's spiced up the design with some aerodynamic improvements and more weaponry, not to mention his characteristic hull textures. The cockpit proportions help convey the size well and combine with the rest of the styling to get across a strong light fighter feel. SWC's original is also pictured below. You can find more fighter images from the Mac/3DO remake here.
Add a modified super hornet to the list (extra tail fins and third laser gun on the underside) to give it a little bit more detail. The original [SWC] model was quite flat and a bit boring.
