Commander is among the many Clone Commanders. If you have a PSP and the game "Star Wars Battlefront Renegade Squadron", when you customize your clone, you can be him along with many others. This is the back of the minifigure.
The little design on the arm is a decal I printed off the internet. I cut it out and pasted it onto the arm.
Now, we are going to see the similarities and differences between Commander Neyo(right), and a regular Clone Trooper(left). These are the fronts. For Neyo, I used a Clone Recon Trooper body.
Here are the backs. The design and coloring are different.
Here are the side profiles. One has a decal, the other does not. But, they both have complete fins on their helmets.
Finally, here are the close-ups on the helmet's designs. On Neyo, the bottom segment of the black part on the helmet(see Clone Trooper on the left) is missing and is replaced with dots instead
