Entity 612

Entity 612 is a newly appearing entity who appears on people's worlds after Herobrine, Entity 303, or Null has done so already. He builds magnificent structures and drastically alters the landscape of the worlds, in addition to causing technology near any computer he is running on to glitch and warp to his will.

captainkawaii666's Encounter (First Encounter)
I was playing Minecraft over at a friend's house. I loaded up a new world just for funzies, and I had some fun building stuff. He joined the world (My friend, not Entity 612) and we started making a huge mansion in Creative mode. I left the room to get a can of soda, and when I came back, my friend was across the room from the computers. I asked what the deal was, and he said Entity 303 had appeared, and... Yeah, our mansion was on fire and there was a 303 file in the folder I keep Minecraft in. We were kind of spooked, but we built the mansion again, and just as we finished, I got a message in the chat.

HI CAPTAINKAWAII666 AND CRAZYWOLF26 HOW YA DOIN

who r u

RIGHT BEHIND YOU

I turned around (in game) and he was there. I asked him what was up, and he kind of just went haywire. He threw a weird glitchy spawn egg, and a creeper spawned in... But this creeper was red. It exploded, and suddenly the mansion, the nearby village, everything was gone. In their place was a huge castle made of... I believe, like, enchanted rainbow dirt or something? I dunno. He teleported away, and we switched to Survival and started exploring the castle (Me and CrazyWolf26 are dumb like this). Suddenly, the Amazon Echo in the room said, "Hey, new pals, teleport to these coordinates." And then my phone got a text saying, "X:612 Y:612 Z:612". So... We did.

We ended up in another weird castle, and we were in Adventure mode with full diamond armor and bows with Infinity and Mending 3. Entity 612 was standing on a platform above us, throwing down spawn eggs, fireballs, and unsuspecting untextured zombies like heck. So me and CrazyWolf26 did the only logical thing:

We yelled "Boss fight!", high-fived, and started shooting at the guy. A lot of arrows and flying ravagers with shulker projectiles later, he finally died. He told us that we were no fun, via Amazon Echo, and then he was gone.

If anybody else sees him, let me know and put it here, okay?
