Sigma's face flipped upside down didn't have the appeal of the original sprite he was going to parody.

I decided that when he flipped, his mouth had to take on the traits of his jewel, and the jewel could then morph into an angry mouth.

@LuqmanGGvevo I read somewhere that Sigma was based on a combination of a trio of designs, and that those designs were loosely used to develop the X Hunters.

If you combine Serges' brains, Violen's brawn and Agile's speed, does it make a Sigma?
