I feel like it depends on the character, honestly. I've known plenty of people who legitimately love to hear themselves talk and if it's a character who desperately wants to be taken seriously/show their own intelligence, it fits even not in the situation of a super hero story.
Hey! I'm not entirely sure if this would be the right place, but I really could use some advice. This is going to be kind of long. Trigger warning I guess for questions about creepy relationship dynamics? I'm writing a world that is, aesthetically, based on a loose mix of bronze age Crete...
