New Minecraft Bosses and Drop Loot

I think we should get more bosses to Minecraft. Like these bosses have the chance to drop legendary weapons like bows, swords, and even maces. I think it would be nice but… you would have to craft legendary stones with expensive things like netherite or diamonds to go to the boss dungeon. The bosses could be multiple different things like zombies, skeletons, or any other mob like that. I also think they would have the chance to drop legendary armor like a mega warden dropping a chest plate that does a sonic boom. Thank you for hearing out my idea. I would like this to be in the game permanent not in the marketplace or any mods.
