ah, yes but at the same time in all of the history of Anime, Manga & stories in general Pain(Pein) is hardly the first to go about resurrecting a bunch of dead people all at once so it wouldn't really be a rip off of that specifically

though the time travel to bring Erza back (providing she actually is dead, Mashima forbid) or save her (if she's instead mortally or fatally wounded) is still a possibility
