Described in the Sonic Wings 3 strategy guide as a "zero-style super dreadnought tank," the Do-ni Revision first appears as a giant tank with a three-cannon turret. After taking some damage, the turret is destroyed to reveal a much more futuristic turret marked with the eyeball symbol of the Hildroid. The Do-ni tank may be related to the Hildroid Tank which serves as the first boss of Spinal Breakers. However, the two tanks are not identical.
