Speaking of A Shadow Falls,
I wrote some story changes a while back, specifically to clean up Nash, Necalli, and Karin’s situations. The same events happen but the context is a bit different. Like the fight between Nash and Urien.
Urien doesn’t actually beat Nash. They fight to a stalemate. The point of the fight is to highlight Nash’s understandably cynical behavior, his suspicion of Helen/Kolin, and his background in psychiatry.
Nash picks straight at Urien’s insecurities, prompting the would-be overlord in a state of madness as he keeps trying to overpower him. While it is made clear that Urien has an advantage, Nash is not easily beaten as implied in the initial narration.
Karin’s situation was more cut and dry. Drop the Mary Sue nonsense and have her motivations in line with the idea of self-improvement and “fixing” the martial arts regime to be less nefarious (based on her personal analysis of what happened between Alpha and SFIV, and what Sakura and Ken periodically tells her).
Necalli in my narration is actually a subject of the Illuminati, heavily implied to be Urien’s creation in understanding ki and the idea of the Satsui no Hadou, giving him the ability to absorb (eat) other strong warriors. Necalli was released a while before the start, which leads Urien’s direct involvement in foreseeing the destruction of Shadowloo through Nash, Necalli, or his own fists if necessary.
Ryu and Bison’s “Final Fight” happens…
Far more earlier that it was supposed to.
Ryu makes use of Mushin while Bison uses an exaggerated form of the Psycho Power when the Black Moons are active. The fight plays out more or less the same as how a fight from the Raid series would have (this is an abstraction). Before fighting with Bision, Ryu has another issue with the Satsui no Hadou, but in this case Kage (who played his own role in also causing Sagat and even Sakura problems in my narration).
Ryu and Bison are evenly matched. Ryu’s arch ends but he actively participates in the efforts to shut down Shadowloo and the Illuminati (the latter which obviously cannot happen because… well… 3S exists).
The last chapters are going to address Chun-Li, Nash, Cammy, Guile, and Rashid’s character arches.
In the short term, I would have set up Nash and Guile to “physically” deal with Bison (optionally his other henchmen) in a desperate struggle.
Chun-Li deals with F.A.N.G. again after the latter has been… roasted and beaten to near-death by Rashid. Before she could rescue Li-Fen, she has to deal with Bison whom is enraged by his lost against Guile and Nash. After getting a better reception, Guile on Chun-Li’s communication line tells her to take Li-Fen and get out but it was too late. Chun-Li fights Bison… a superpowered, ghastly form of Bison that was generated from the computer systems of the Black Moons and remaining hidden Seth clones.
She ekes out a win and takes Li-Fen out of the Shadowloo.
Thus leading into SFIII.
Or… SF6, depending what the hell Capcom is trying to do.
Or… some other narrative pushed onto SFV in its remaining time which is somewhat likely.
