Man, that's a pairing I've seen polarize folks, but I always end up defending it for exactly that reason—the growth potential. People get hung up on Bakugou's aggression in the early series, that sludge villain incident where he yelled at Ochako. But if you trace their arcs, they're both climbing the same mountain from opposite sides. Bakugou's whole thing is learning to be a hero who saves people, not just wins fights. Who embodies that selfless, rescue-focused ideal more than Uraraka? Her motivation is purely to help her family, zero glory-seeking. I think a good fic for them wouldn't be a romance that starts early; it'd be a slow, grudging respect post-war arcs, where he sees her tactical mind in action during a joint agency internship. She's not afraid of him anymore, she'd just call him out on his crap with this terrifyingly calm smile.
What really gets me is how their insecurities could mirror each other. Bakugou fears being weak, left behind; Uraraka worries about being a burden, not strong enough to lighten others' loads. There's a fantastic oneshot I read where they're stuck in a disaster zone, and he's injured. She has to use her quirk creatively to get them out, and he's just silently watching, furious but impressed. It's not about him softening for her, but about him recognizing a kind of strength that isn't about raw power. Her growth is learning to be selfish sometimes, to fight for her own goals, and who better to unintentionally teach that than the guy who's all about ambition? The pairing only works if you take them as they are later in the manga, not their first-year selves. It's a real 'five years later, they meet at a top ten heroes gala and actually have a civil conversation' vibe.
