Due to lots of research and never seeing herobrine in my life it has come to my conclusion that herobrine is not on PC and only on xbox (possibly on pocket edition 2. I must admit I have not been on minecraft for 6 MONTH AND I AM DYING, luckily im  getting a kindle fire tommorow and can finnaly play minecrat P.E.   Anyways on every update of minecraft PC it says -removed herobrine to toy with the comunitie BUT even if it was in PC it has been removed like a thousand updates ago.

Every picture I see of herobrine is on a server with someone else with the skin of herobrine or on a single player with someone that pressed F5 (or F4, IM SO CONFUSED IM FORGETTING). I can tell because there is no fist.  real herobrine is in the Pc m0

The only ever herobrine that is real is in the herobrine mod (Never tried it, im quite He destroyed the bed blew up were he was and turned it to peacefull straight away as he disappered he never saw it again.

Anyways due to this its true he is only in Xbox and possibly on pocket edition (I hear hes alway near the nether reation, so now i wont make a nether reacter) ):.

Update for this blog: just found out that Herobrine was MADE ON XBOX! When notch first heard of heroine he thought it was a neat idea, he could not make it as smart as a player so he made it just smarter than a villager with a hint of zombie personality.
He will spawn randomly in light or dark and just wander around. Killing people would make people creepy out and never play the game again. Sorry people who play Xbox but he's real
