The player mini boss

To access this boss you have to put all your stuff you died then was in your hotbar with at the exact same spot you died with and the mini boss will come out the ground then the weather will be lightning to make the boss more emotional.

The boss will look like the skin you died with. If you change your skin when you died the boss will stay the same skin as you. This mini boss will have the stuff you dropped to summon this mini boss.
Hearts: 40
Rewards
1) the stuff you dropped
2) 15 xp points
The attacks would be like a normal person in Minecraft but a bit stronger
When the player hits you it has a little more knock back. If the player has a wepon (ex: diamond sword) you will have the same affect but more damage. If the player has blocks in their inventory the player will protect themselves by surrounding it with the block (ex: dirt, oak wood, etc)
Heres a useful tip: If a Zombie or a skeleton are nearby they will get confused and start attacking the player, if the player is killed then they'll kill you next.

I hope you like my suggestion Mojang :)
