Hardcore Mobs(Titans, Sea Bosses,etc.)

Survival Mode is a lot easier for Other Players to Play the Mode but what if Mojang Adds a Hard level Mob? Like in the Forest or Jungle, We sometimes travel and scout in the forest but it's kinda boring seeing no treats on a daylight morning. What if you can allow hardcore mobs like Large Creepy Humans(Titans), Huge Bird that flies through the sky and is capable on attacking you in the day, Making a Giant boss in the Ocean that kills anything on sight? The Raid Feature is Good and I commend mojang for it but now, I can't see pillager scouts roaming in the forest or Anywhere. Please add a Titan Feature in which your House or The Village will get wrecked by these Huge Monsters. And also add able and disable hardcore mobs so that other players can turn off this Feature if they think they can't survive. I'm a Player on Minecraft until now, Please grant my wishes. Thank you and I will look forward for new updates on minecraft.
