I'll nominate the deletion of this entire verse:
https://vsbattles.fandom.com/wiki/Mazinger_(Verse)
While the pages being kinda wonky and unsourced is apparent to everyone, as someone who's very much into the series, I can tell you they're almost all composites. Probably the best examples of this is Mazinkaiser, who's being scaled to FTL from a feat in the Toei anime, despite that in no way being canon to the Mazinkaiser anime (aside from the radically different designs, Mazinkaiser has Dr Hell still active against Great Mazinger and shows Mazinger Z being destroyed, when in the Toei anime Hell was dead when Great Mazinger was introduced which was AFTER Mazinger Z was destroyed), while also being scaled to Mazinger ZERO, when the ZERO manga is ALSO not canon to either Mazinkaiser or Toei (it has radically different origins to Mazinger Z and Great Mazinger than those shown in those shows, in addition to Mazinkaiser never appearing in it), and most insane this is because the key is named ''SRW Kaiser'', meaning the source is Super Robot Wars, a video game. Some of the stuff in these profiles are just straight up lies, like saying Grendizer is comparable to Mazinkaiser, when the 2 have NEVER been in the same continuity, every Grendizer series omits Kaiser and vice versa.
The only profiles that AREN'T composites are God Mazinger and King Dorado, and you judge if those should also be deleted or not.
