He drinks the blood of his allies and the neutral creatures, gaining their abilities as he does. They then become his thralls, and follow him wherever he goes. Little by little, Sonic builds a thrall army, and eventually turns them all on Robotnik's forces. The final battle comes, and it can only end in one of two ways...
- Sonic gets a stake in the heart by Mechasonic, thus Robotnik saves the world he's tried so hard to take over.
- Sonic drains Robotnik of blood, thus enabling Sonic to bring his world into a dark chaos... with him ruling over all as a vampire lord.
