I wouldn't read a Pokemon comic in any form, except maybe to laugh at it if it's uniquely and unusually awful.
Fan comics tend to be
Mary Sue showcases, self-aggrandizing self-insert stories where a thinly-veiled avatar of the author saves the day and wins the love/admiration/jealousy/etc. of the entire principle cast, flaccid attempts to make the property "edgy" or "more adult," uncomfortable attempts by the author to work through issues with their own sexuality, or just plain boring and badly-executed. And when I witness the rare event of a well-done fancomic, I just consider it a waste of time and talent.
If you enjoy Pokemon this much and feel you have a Pokemon fan-story in you just bursting to get out and be told, by all means, don't let me stop you. Go for it. But you asked me if I'd read it, and nope, I wouldn't. And don't make it under the illusion that Nintendo would potentially ever have anything to do with it, ever. They likely have their own Pokemon comics, with editors wrangling authors and artists to tell company-approved stories that fit established canon.
