The fastest thing alive in the Christmas spirit! Sonic is compatible with MMD motion and pose data. He has several morphs as well as physics for his hair.
This model comes with .fx files that can be used with MME to activate normal mapping on the model, as shown above. For more information, please see the included help file found in the model's folder.

This download contains models that are only designed for use with MikuMikuDance (MMD).

The original model of Sonic was ripped from Sonic Generations by Apoc Hedgie.
The outfit was ripped from Sonic Runners by Hallow.
I did the conversion work for the MMD model and put the two models together. I also added the woolly effect to Sonic's coat.
