Kenjaku from JJK, in Geto's body, finds himself in Soul society.
-Before Canon. Timeline not determined.
- Power system. Either separate or merged.
So he either has both Cursed energy AND shinigami abiltities. Or those powers merged and became one.
- Kenjaku canon. No Mr nice guy.
So evil. Won't feature things like *Grape, but experiments and evil might still appear. So it might be implied. (Depends on your opinion. Don't want to make anyone uncomfortable.)
- Powers will be complicated.
His powers were never really well explained, so it'll be difficult to to it well. I'll write down everything i know, and everything i theorized separately.
Known abilities:
-Smart as fuck. (Figured out how to beat Takaba's absolute cheat of a Cursed technique.) Is a manipulator and his knowledge of Binding vows and rituals are incredible. Not to mention his barrier techniques.
-His cursed technique can transplant his brain (and probably his soul) from body to body, thus achieving longevity.
-He retains powers, abilities and Knowledge of the body he inhabits.
-It is theorized that he might retain a limited amount of techniques while hopping from body to body. (Gravity manipulation for example).
-It's also possible that his Gravity manipulation stems from Suguru Geto's Cursed Spirit manipulation.
(It was stated that powerful Cursed spirits techniques could be extracted. So gravity manipulation could come from a cursed spirit he consumed.)
-Has a domain expansion. It is called Womb profusion, and probably can serve as a conductor, for multiple Cursed techniques.
(I think he combined Geto's Cursed spirit manipulation with Gravity Manipulation in the Manga? I'm not too sure. Please clarify.
How this would play out in Bleach.
-Depends. If his Original cursed technique really stores the techniques of prior bodies, then he'll be really powerful.
-Deoending from what point we take him away from JJK, will heavily impact Geto's cursed technique. (Amount of Cursed spirits he takes with him.)
-Geto's technique, (and maybe even Mahito's if we take him right at that time) will be heavily altered. Geto's will be heavily altered, to make it fit bleach. Basically controlling Hollows... and maybe even Normal souls. This is undecided, so let me know what you think.
