>Red>Ethan>Brendan>Dawn>Hilbert>Rosa>Serena>GloriaThe opposite gender MCs have some traits that the actual MC has. Lyra says she battled Red, but she also says her grandparents run a daycare, she has a Marill, and her starter is weak to Ethan. Leaf is from Pallet Town and visited the Sevii Islands (so did Red), but she's treated as an acquaintance of Red and Blue rather than a rival like they treat each other, and her starter is strong to Blue's. Kris seemed to go through a lot of Crystal's unique events like meeting Suicune. May is explicitly said to be Birch's daughter, but her starter is weak to Brendan's despite her being the rival. Dawn is neighbors with Barry, but she has the starter strong to his. Lucas is Rowan's assistant. Hilda is battle crazy and doesn't know N personally, so she's the Battle Subway partner. The Battle Subway is alluded to many times with Nate, but he also seems to be friends with N and has strong feelings over what Team Plasma did in Unova. Rosa mentions having met Iris on her travels. Calem is the rival because he uses Meowstic and references what he said to Shauna and going it alone. Elio and Selene both have quite a few traits suggesting they're the protagonist with nothing definitive confirming or denying. No Victor yet, but Gloria is pretty much the protagonist.
