theres only like 5ish scifi shows on that list. i mean rocko's modern life? it makes no sense. Therefore:
Space Runaway Ideon!
where else can you see a child get decapitated by a laserbeam?
(actually its pretty bad mostly.)
the various gundam shows include both some of the best and some of the worst scifi cartoons in my opinion. excepting the 08th MS squad-team-force miniseries-series, the general rule is it gets worse as it goes on.
