In the comics, it's a complex situation. Different storylines might have different outcomes, but as of the common ones, no one has directly killed Homelander.
Well, Homelander is a complex and often self - centered character. If he were in an Avengers fanfiction, he might initially see the Avengers as a threat to his own status. He'd probably try to assert his dominance over them, thinking he's superior. He could start by showing off his powers, like his super strength and laser eyes, to intimidate the Avengers. But the Avengers, being used to dealing with powerful foes, would likely see through his bravado and not be easily cowed.
The following are a few recommended novels where the protagonist kills the enemy with a heavy halberd:
1. " I Possessed Lu Bu ": The main character becomes Lu Bu, wielding the Heavenly Halberd, and becomes famous in the dynasty struggle.
2. [Evil Martial Divine Emperor]: A down-and-out young man awakens his bloodline, wields the world-suppressing Evil Halberd, and with a single halberd, he suppresses all directions, ruling the nine heavens and ten lands as the emperor.
3. [Poison Seizes the World]: The story of the protagonist fighting against the world with a halberd hidden under his sleeve.
I hope these recommendations will meet your needs.
