Tired of adaptions, reboots, and remakes in your sci-fi anime? Frustrated that MAL doesn't allow you to filter by source material? Well, this list has you covered.
For the sake of including as much as I could, I've only listed one entry from each franchise/series (generally the first installment). Some entries have a manga that came out shortly before they premiered, but those aren't really adaptions since the production of the anime predates creation of the manga.
