WANTED: More unused sprites. I imagine there are going to be a few, including leftovers from the original version of the game. Please send any findings to me at: rage-quitter-87 at hotmail dot co dot uk
EclipseVoid found this unused enemy. It appears to be a ninja with claws which can grab onto walls, and leaps around to attack. The above palette isn't correct but it makes it easier to see. SEGA created A.I. for it, so why it got cut out is a bit of a mystery. EclipseVoid even created a view showing how this enemy would act in a level, see it here.
