I remember believing in my own conspiracy theory that Iono was related to Team Star in some way before the game came out because of her star symbol, one of the flags being yellow, and her wearing oversized clothing like Mela.
Another one that I believed was Iono being the gym leader who was also an e4 member back when Kaka first leaked about that because she had Magnemite hair clips, and that Khu posted a batch of Pokemon hinting at what Pokemon she´ll terastalize, one of the options being Bronzong, with her jacket resembling the shape of a Bronzong as well. So I was guessing that her using the Magnemite line and terastaliizng Bronzong would easily transition into a steel e4.
And now that I look back after the game came out, I also realized her hair splits into 2 similar to how Tinkaton´s hair splits into 2. So I wonder if that might´ve originally been the case since Poppy was likely the last e4 designed since she appears the least in the game out the e4.
