In the wild summer of 20XX, a cosmic mishap in the D95 world accidentally took out an otaku on rent-collecting duty. To dodge a bad rap, the system secretly compensated him. Unhappy from a loveless childhood and a life of collecting rent, the otaku opted for a wild reincarnation—he picked Broly from Dragon Ball to tackle new, lower-dimensional adventures and chase his dream of collecting figurine "wives." But when the system got so caught up creating a “harem system” that it forgot to secure his soul, things got even crazier: by the time the harem system was ready, his soul was absorbed and reworked by a Saiyan embryo. The end result? A whole new, power-packed reincarnation—leaving the system scrambling off with promises of future compensation.
the idea of someone with brolys powers going around the multiverse is interesting. (the actual canon broly character doing so? not so much) the execution leaves much to be desired though. my two issues are the slave system being basically the “actual” main character since it dictates the flow of the story and since you chose to write a convoluted premise with having the original a si’s soul get taken over by the brolys own soul. yet decided this supposedly new broly acts more or less the same as canon broly alongside a low int value. i wonder why use this convoluted premise? if the broly in this fic is more or less the same as canon? it just seems needlessly pointless. the problem comes is that the system and the prior si act like a voice in their head directing the original broly. its just kinda boring since there isn’t much one can do with such a brainless character. most interactions are going to become really stale. i know this is a fanfic and not much should be expected from it. i think it’d have been better had you just had the si soul take over a broly body without any of the shenanigans no rob wishing sequence or gifting and just done it inexplicably with no explanation to protag. i personally don’t like systems in general but for the sake of an interesting premise or concept i can stomache them usually. basically a good idea but bad execution. as a brainless main character + voice in their head slavery system thats the real main character doesn’t translate well.
