>>53838994The translation on danbooru isn't quite right. According to google, the japanese text "プレートじゃねえか" apparently is spoken verbatim by Volo in PLA, in reference to either the Legend Plate or some other one of Arceus' plates. Here look:
https://www.youtube.com/watch?v=oBsTcUKw_AgI don't know what's going on in the exact cutscene. Anyway the first half of that phrase "プレート" sounds like "purēto" which to me looks like a Japanese attempt at phoenetically saying the english word "plate." The rest of it, "じゃねえか" means something like "isn't it" or "isn't that" or "ain't that" which is a little bit odd, because you'd think "Isn't that a plate" would end in a question mark rather than an exclamation point. The grammar of what the people are chanting is a little odd. But nobody is saying anything about iron. They're saying something on screen is a plate, or looks like a plate. They're talking about Jasmine's gigantic forehead, as referenced in an earlier panel. (Also a previous line of dialogue from the audience is asking of Iono's bangs disappeared due to a graphic bug)
