Sonic.EXE

No more jokes: the Nightmare Sonic has come to destroy your Minecraft world. If you're lucky, you might survive after installing the Sonic.EXE mod. Sonic.EXE is a creepypasta character, so adding him to the cubic universe was not the best idea, but developers did it to spread fear among all users. The mob has 666 health and instantly kills any creature. The mob has a unique ability to kill all living creatures within attack radius. Moreover, the mob can fly. The monster also makes a roar that kills all living things. If that's not enough, Sonic can change the player's game mode from creative to survival. The screamer will freeze and kill any creature. Sometimes the monster might even spare the player. Sonic spawns randomly in the game.
