Why the interest in Sydrome?

For me it's that in many games you don't really get the chance to play as the villain, and when you do it's usually from a cheat of some sort. So to have the main villain a playable character AND have his zero-point energy seems really cool and exciting imo.

I don't know why but for me it was because he was determined cool and made really cool inventions

My interest in Syndrme stems from the fact that they are making villains for Infinity. It brings a new dynamic to the Toy Box if done right.
