Red Dead Redeemed
Smash Journeyman
Funny enough, it was because he got screwed in such a humiliating fashion that I became a Chrom supporter. If the trailer was exactly the same and Chrom wasn't lying in the dirt lamenting his fate I would have been perfectly happy, Robin with Lucina as a bonus would have been good enough FE representation for me. Then the game had to put salt in the wound with a (admittedly pretty funny) Palutena's guidance and it only made me root for Chrom even more. I love a good comeback story.I mean, he already got screwed in that Smash 4 trailer and it basically became a meme up until some time when Warriors was announced.
I guess that's what endured Chrom to me though. He isn't the best written FE protaginist, but the game was never shy about making him the butt of jokes or putting him in his place if he did something stupid (his support with Gaius sticks out to me for this reason). That always made him feel more real to me, as opposed to someone like Corrin, whose entire narrative was basically a glorified self-insert fic where everybody loved them, and all the characters motives were centered around Corrin no matter what horribly questionable choices they made. Or (about to stoke the fires of the entire fandom on me) Ephraim, who after playing SS again with Nostalgia blinders off, really started to wear on me with how the narrative wanted to make him a super-man that could do no wrong, and whose only flaws were either Mary Sue-esque non-flaws that doesn't effect him in any way (him being referred to as book dumb just reminded me of poor writers saying "she has a temper" when asked about what flaws their character has) or just completely irrelevant to the main plot on hand (whether he was worthy to be King or not, which I feel Erika was a far better fit for ruler but that's a whole 'nother can of worms)
