《This is an Artificial Herobrine Created Using Minecraft Commands》

First, I need to brief you on something's
This works for 1.16 to 1.19
Herobrine has 350 health
It takes an average of 4 damage, which is 2 hearts
Its movement speed is comparable to a player sprinting and jumping at the same time.
Pick the items in your inventory wisely.
I recommend normal terrain for battling.
Good Luck=D
