It starts at a specific point in the manga, but I can't recall exactly without looking it up. You might want to check some manga forums or dedicated fan sites for the precise chapter.
It's hard to say for sure. Both Sukuna and Gojo are incredibly powerful, and it could depend on various factors like their current state and the circumstances of the fight.
Sukuna does die in the manga. The way it happens is quite dramatic and ties in with many other elements of the story, adding depth and tension to the overall narrative.
There are many novels related to Plants vs Zombies! For example,"The Legend of the Botanic Card Creator","The Botanic Mountain Monarch","The Great Botanic Overlord","Overlord: I Summon Plants vs. Zombies in the Abyss","Where Are the Magical Plants?" Doomsday Plant Lord, Super Plant Zombie System, Family Cultivation: Starting with Plants vs Zombies, I Plant Zombies in the Other World, Playing Plants vs Zombies in the Full-time Mage World, I Cultivate in the Movies, Master Plants, Planting Herbs in the Underworld, and so on. I hope you like this fairy's recommendation. Muah ~😗
No. Ryomen Sukuna is a fictional character from Japanese mythology and modern manga/anime. He doesn't have a basis in a true historical event or person.
