Super wins by a country mile with how much it destroys character development or any semblance of coherency along with retroactively ruining most of Z's arcs. GT is probably next as, despite the Super #17 Arc being founded on a plot hole and the Evil Dragons Arc having multiple inconsistencies, the latter at least had a good premise and the characters weren't butchered as in Super. Gundam UC comes next for ruining the themes and tone of the Universal Century storylines. The Saint Seiya spinoff's ranking depends on which non-canon one we're talking about (because there's at least a dozen
), with something like Omega or the Netflix series going in between Super and GT whereas something like Lost Canvas being far less egregious than the others already mentioned. The other Gundam spinoffs come next by making it very clear their timeline is divorced from the original and are unable to infringe on past characters, and I have little knowledge or care to rank Arc-V.
