Anyone have ideas for making a BOSS/BOSS battle?

Me and @Pixel_Name1 discussed some advice on creating a good boss battle. Perhaps they could be helpful for you.

3. Boss Fights

The best part of any game is getting to the end and defeating that hard boss that you’ve been preparing for. You may feel that your game needs that near to impossible boss battle, but you need to remember that you need to give your boss weaknesses to make sure that the player would be able to defeat it. Look at Minecraft for example. Its boss the “Ender Dragon” has end crystals that you have to destroy to get its health down, that is its weakness. Also make the boss fight fun, I would suggest going to family and let them play your game and try and defeat your boss then ask them what they liked and what needs to be changed.

Adding on to what @Pixel_Name1 is saying on point 3, it would also be a good idea to plan ahead on what your boss is like. Try making concept art, or a list of planned actions and conditions. You also want your boss to fit the game. Does it work well with the game’s mechanics? Does it align properly with the difficulty?
You can also try experimenting with the boss’ mechanics to see what works best. And it’s okay if you’re not satisfied at first; trial and error is a good learning experience and can lead to new ideas that can solve previous problems.
