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.
There was no clear conclusion on the strength of the Primus Crocodile and the Titan Python. The search results did not provide any data on the direct battle between the Primus Crocodile and the Titanoboa or the comparison of strength. Therefore, it was impossible to determine who was more powerful between the Primus Crocodile and the Titan Python.
It's really hard to say. Godzilla has his massive size and powerful atomic breath. But Titans in 'Attack on Titan' are also very large and strong, and some of them are extremely fast. If Godzilla could use his atomic breath effectively, he might be able to take out a lot of Titans quickly. However, if the Titans could swarm him all at once, they might be able to overpower him.
