This is the ender dragon fight from an entire challenge run I personally did where I beat minecraft with only a stick, along some exceptions
Here are the rules:
-my only weapon could be a stick (apart from snowballs for blazes)
-i am allowed pickaxes, axes, and shovels, but only pickaxes could be up to iron
-no armor or shields as that would drastically reduce the difficulty
-must be a random seed
-other miscellaneous tools like buckets and boats are allowed too

Music used:

War Without Reason - Ultrakill
Dry Hands - Minecraft

Subsribe please :)
