>>51184080>>51184122I think the cool Oneesan would be repetitive after the OC of the Mew project.
I would prefer a bumbling hard headed and stubborn rookie, with an iron will, even if she was a walking failure, something like Risa in the Zeraora movie, it would serve as a contrast to a now veteran Ash who is no longer going around after the medals If not, he is in the "Champion" category and is looking for more opponents to measure himself in this category while Nemonas is now the one who is looking to enter the Paldea league.
The difference with May and Dawn apart from being a tomboy is that despite being a big loser she never loses her enthusiasm, she would basically be the cliche shonen lead.
Also to give a twist to the dynamic, she always exaggerates her feats and exploits, making a naive Ash always amazed at her stories, so even though she is the rookie in pokemon battles, she takes center stage in the series with Ash as his hyper-competent sidekick. Basically the series would be a parody of Don Quixote de la Mancha, with Nemona presenting herself as a great trainer and trying to help others with their problems, only to make things worse, Ash resolving the conflict and Nemona taking the credit and Ash celebrating it, before the astonished look of the spectators who do not know which of the two is more idiotic.
