I really like this one from ARticWolf999

The battle was going great, until GlitchedXP died. He and Herobrine were fighting when a group of 50 skeletons stopped shooting at Gameknight’s archers, confusing them, and fired simultaneously at GlitchedXP. only 10 arrows found their mark, GlitchedXP deflected the rest. But those 10 arrows shredded GlitchedXP’s HP and killed him, allowing Herobrine to step up and collect his XP. Gameknight groaned. he knew Herobrine would now have GlitchedXP’s abilities. As soon as Herobrine gathered up the XP, he fell over screaming.
“No, NO! I AM HEROBRINE!!!”
A calmer voice sounding Like GlitchedXP’s said
“You are MINE!!!”
“NO”
Herobrine was lying on the ground face down, when suddenly he flipped over and revealed a purple eye, as well as a normal (for Herobrine) white eye. Herobrine and GlitchedXP began fighting a battle of wills, and it was clear GlitchedXP was going to win. He outstripped Herobrine by a mile when it came to this. With Herobrine having appeared to have gone insane, the remaining Mobs fled, and suddenly Gameknight heard GlitchedXP calling for him.
“Go! Run! NOW!!!!”
Gameknight wasted no time, him and his army fled as fast as they could. They looked back to see a pixelated mushroom cloud rising from where Glitched-Herobrine was and they could hear Herobrine and GlitchedXP yelling in a weird double voice:
“NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!!”
