To write a good 'Homelander Fanfiction', first, understand his character. He's complex, with a huge ego and a lot of power. Start with a unique concept, like putting him in a situation where his powers are useless. Then, develop his character further. Maybe show a side of him that we haven't seen much in the show, like his fear of being alone. Use vivid descriptions to bring the story to life.
Definitely. The comic version of Homelander is portrayed as having greater strength and capabilities. This is evident in his confrontations and the scale of his power displays throughout the comic series.
