Dangerous land

Currently, there aren't many dangerous biomes in Minecraft Overworld, so I thought about this biome.
This dangerous land is centered around the Black Desert, surrounded by brown forests surrounded by large rivers.
The reason for the danger is the emergence of wild Ravager (texture different from Ravager), this biome has a much higher creeper spawn rate than other biomes, this dangerous wither rose is produced only on land, and the weather is There are always thunderstorms, the most thunderstorms, and dangerous mobs that only appear in this biome.
Troll ... slow-moving, but the same size as Warden, mainly in brown forests and the Black Desert, with a significantly larger nose.
Owlbear ... A mob who walks like a gorilla with a bear and an owl and appears mainly in the brown forest, but is very warlike and ferocious.
Hunger ... A dangerous monster that constantly seeks food that appears in the Black Desert, and a dungeon "Dangerous Fortress" built in the center of this dangerous land.
Dangerous Ruler ... A boss mob that appears on the roof of the dungeon "Dangerous Fortress" in the center of a dangerous land.
Dangerous Fortress ... A dungeon created in this dangerous land in the center of this biome.
Hungry and other monsters will appear, and Bosmob's "Dangerous Ruler" will appear on the roof.
If you have any other good ideas, let us know in the comments. Thank you for taking a look at my thoughts.
