>>51955354From what I remember from Delta Episode, it's just that she feels like an actual fanfic character that bumbles into the plot (it's only recently that I even remember that she technically has an appearance "foreshadowing" her in the main story), acts like an actual insane person in what feels like an even shitter version of Dragon Ball GT's Black Star Dragon Ball arc, ends up being a total fuckup anyway, and then she just fucks off from the game entirely like she never existed to begin with
Some of the especially weird shit she does like knocking out the MC and her pre-fight animation kind of feels like that sort of early 2000's specific OC that you would find on Deviantart or
Fanfiction.net, everything put together just comes across as unusually strange even for a Pokemon character
