would the soul merge with the other soul or would their body reject the soul and maybe kill those who tried to absorb the soul? it's something that i honestly thought of just now as a sort-of what if thing that could happen in some kind of au somehow, which also leads into another question, what if Flowey could absorb the souls of boss monsters before they die, this is something that i also thought of because of PS!Outertale as Twinkly absorbed Toriel's soul to become Asriel so what if Flowey could do a similar thing but with different boss monsters? what could happen with different boss monsters? could others have better advantages then other boss monsters? that's all i really thought of, but that's it for me for now, i'll just leave you all to think about this
