Trivia

 * Doppelgangers usually are resistant to physical skills of all kinds, usually being capable of reflecting all physicals attacks out-right. This could be attributed to their own nature as shadow copies of the protagonist, were all the harm done to them goes back to the protagonist, for being one and the same.
