My Mixed Reactions On Tekken's Plot Twist On The Devil Gene
It was originally intended in Tekken 5 to make Jinpachi Mishima someone who had the Devil Gene yet his transformation was anything but similar to Kazuya and Jin. The story got retconned which Katsuhiro Harada later said that Jinpachi was merely possessed by an angry ghost. Jinpachi was instead someone who came back to settle scores with his treacherous son Heihachi. He once had a loving relationship with his grandson Kazuya and later opened the King of Iron Fist Tournament 5 hoping someone could destroy him. He's the first neutral final boss in contrast to the other final bosses before him.
So why did the staff behind Tekken 7 decide that the Devil gene should be given to Kazumi's bloodline instead of the Mishima bloodline? It's revealed in Tekken 7 that Kazumi intends to finish Heihachi off to save the world from massive suffering. She hates her Devil Gene heritage. Heihachi ended her life in a life and death battle. Heihachi was later seen trying to end his own son's life and later grandson's life when he saw the Devil Gene manifest. He probably viewed it as a threat to whatever plans he had so he had to get rid of them both.
I think it does make sense to have the Devil Gene not from the Mishima bloodline. Lars Alexanderson appears in Tekken 6 as its main protagonist. He's also the illegitimate son of Heihachi by some unknown Swedish woman. The reason why neither he or Heihachi had the Devil Gene was because they have none of it. Kazumi herself was the host and not the Mishima bloodline.
My bizarre conclusion behind this plot twist is this. I think the people behind Tekken want to show the audience that Heihachi is evil by his own free will. He's probably still Tekken's most evil villain even if there were bigger threats such as Azazel or Ogre. I mean, what kind of person would use his own son or grandson for his schemes? Tekken 3 had Heihachi try to use Jin and later shoot his own grandson. He started the whole mess by overthrowing his own father and later having a conflict with his sons. He's the start of the whole bloodline curse and it didn't take the Devil Gene to do so.
What are your thoughts on this matter?
