You thought they couldn't get any stronger than CaseOh?

I present to you: Ender Sans. My Minecraft/Undertale crossover character.

WARNING: /kill does not work on him and he causes a lot of destruction and kills mobs, so please don't spawn him in a world you care about.

He does not move like a traditional mob and instead has 3 different attacks he can use.

His main attack is summoning bones that kill the target.

MCPEDL

His second attack is summoning lasers that severely damage any mobs in a 10 block radius and spawn TNT.

MCPEDL

His third attack is summoning ghosts around him which attack enemies. Also, this is a good time to say: Please leave a comment, I would love to hear your opinion and feedback. I read all comments!

His fourth attack is summoning red bones that levitate and kill mobs. (Yeah I'm definitely running out of ideas)

His fifth attack is... Well, this.

And his last attack is summoning little tornado guys that send other mobs flying.

That should be enough to get you started. This addon is specifically meant for mob battles, spawn him in survival mode at your own risk.

NOTES:

He can play music, control time, and summon lightning bolts.

He can also display messages and turn your screen red.

The song he plays is a Gaster vocaloid cover of ECHO by Crusher-P pitched down a bit.

I just saw it on an Undertale animation and thought it would be cool.

Have fun!
