Ooh... Nice. I guess SEGA is rather fond of the evil twin or doppelgänger concept.
The "
Evil Doppelgänger" trope is an over-used cliché but it can still be good if done right.
There are three types:
1. "
Alternate Self", which is fairly common, where they come from an alternate timeline or parallel world where they were once the same person as the protagonist at one point but different circumstances lead them to being someone else. The factors that change them could be at a specific point in their loves or perhaps the entire consist of "fixed points in time" that ended up opposite that made the natives naturally be opposite.
2. "
Evil Counterparts" who may or may not be related to the protagonist, but they still possess abilities and skillsets that rival to the protagonist. this could range from
Criminal Doppelgänger (who may only bare a passing resemblence to the protag than look like them) to
Evil Twin.
3. "
Evil Knockoff" is when some other villain decides to fight fire with fire and make their own version of the protagonist to fight for them. This could be done with cloning or robot doubles.
