The Sinister+ Add-on 1.21+/1.20+/1.19+/1.18+/1.17+

Mod The Sinister+ for Minecraft includes one entity, just one, and we assure you, this experience will not be a good one. The monster can appear at any moment, precisely when you are least ready. Besides being able to jump and open Doors, some blocks will not be an obstacle for this creature, and it will break through them.

Overall, the monster has a rather creepy appearance, and every player will be terrified, hiding from this disgusting creature. There's no way to escape from the enemy, which means you are surely headed for certain death. Test your skills against the new boss.
