Im not aiming towards that he is a kratos reskin , point im aiming at is that his personality is more or less the same as shangs.
That's cool man, just saying visually he can't be accused of being artistically unoriginal in the franchise.
To be fair, MK4 is mostly to blame; certainly from Defenders of the Realm and Mythologies they were clearly trying to go for something a bit different with him, but MK4 was basically a soft-reboot for the franchise (which in many ways I really like it for - it had some brutal fatality ideas, tried to bring back that mystic feeling after MK3's urban grunge vibe, tried to strip back some of the franchise's eccentricities that were developing) but also feel they went too far down the reboot road with likes of Kai, Reiko and Jarek who were all just kind of pointless redesigns of the classic characters. Then you have two bosses you can actually play as, really diminished their threat in the game when they're just other fighters from the select screen. Shinnok turned into a twat in a hat who just has a less visually interesting version of Shang's morph ability whilst Quan Chi was just rather generic as a fighter.
On that subject... Weirdly I really enjoyed Shinnok as an FMV character in Mythologies the most. He was a creepy yet seemingly very soft-spoken old man; it made knowing that he was apparently an all-powerful force of pure evil all the more interesting to me. The fact that he was just there in Bi-Han's prison cell, chatting away like a kindly gentleman at the post office made it feel all the more like he was toying with him. True power doesn't need to prove itself, it has fun with just mocking your perceptions of it.
Anyway, I digress, Quan Chi may not have too much uniqueness to him, yet actually enjoy the fact that he and Shang share certain powers, for me it makes them two sides of a coin. Quan Chi a demon from the Netherrealm who harnesses the natural power of its realm, Shang a disgraced human traitor looking to harness that same power and dominate it. For me it's more about two different individuals controlling those same powers and the character conflict that creates rather than analysing them as playable fighters in a video game.
But hey, that's why I've liked Mortal Kombat, I enjoy its lore and the imagination it sparks in me
