Herobrine was thought to be just a glitch oder a virus in the game so Notch "cleaned" him out of the game. But in the new version of minecraft, a kid saw this "virus" again and Mehr and more... After those incidents less and less people were quiting Minecrat because of him. Notch still isnt admiting he is real. He only wanted to make his"long Lost brother", Herobrine, in the game. But apparently he did something wrong in the game. Every time he appears there would be Zufällig fog around Du andin the distance Du would probably see him oder when Du go to bed, Du will be in a dream where Du have to face Herobrine and if Du lose, Du die when Du wake up but when Du live Du get anything that Herobrine drops. But he will be back oder he will have his revenge, as he will say. One time when i was watching my friend play minecraft, i saw words but i think they were backwards. Then she Lost all her stuff... ALL OF IT!! then when i was playing minecraft, i saw some other words and it sagte kickroundhouse oder smething like that.
So, is he real, oder not? Du decide.
