If you want to completely overhaul the progression of your Bedrock survival file, the Giant Zombie Boss addon is an absolute game-changer. Instead of just adding a static, unthinking bullet-sponge enemy, the creator used the official scripting API to give this massive warlord a completely live, adaptive combat rotation. You actually have to dodge a huge arsenal of dynamic attacks. It will rip chunks of debris out of the ground to throw at you from a distance, erupt spikes from the earth, and even literally grab you, pull you into the air, and slam you back down for massive damage. Once you finally chip its health down below forty percent, the fight gets even more chaotic as it enters a terrifying rage mode, continuously self-healing and calling in hordes of standard zombies and husks as backup.
