One popular plot is the discovery of a common enemy that forces Superman and Homelander to team up, despite their differences. Another is a battle for supremacy in a world where both exist, with different factions taking sides. And then there's the plot where Superman tries to reform Homelander, seeing the potential for good in him.
Well, it depends on how the fanfiction is written. If it's a more 'grounded' version where Homelander's public image and mind - games play a big role, he could potentially gain an upper hand. But generally, Superman has more raw power. He can move planets, and his speed is almost limitless. Homelander is strong and has flight and heat vision too, but Superman just seems to be on a whole other level in terms of pure power.
Vegeta would also be a major character in these interactions. Their Saiyan bond could lead to different scenarios. Maybe Vegeta would be initially angry that Nappa survived but then come around to the idea of having him as an ally again. It could also be a source of conflict as they might have different ideas on how to handle certain situations.
Mike Nappa is indeed recognized as a Christian fiction writer. His stories usually explore faith-based concepts and characters' spiritual journeys in an engaging way.
Well, if Nappa turned good, it'd be a huge twist. He could end up teaching the heroes some powerful techniques or sharing insider info on the villains. It'd definitely shake things up!
One key element is Nappa's character transformation. Since he's usually a warrior, seeing him adapt to diplomatic ways is interesting. For example, in some fanfics, he has to learn proper etiquette.
