How can I create a Wither Storm (from Minecraft Story Mode) in Minecraft? [closed]
Solution 1:
The Wither Storm is not present in any normal edition of Minecraft. It was created entirely for the purpose of Minecraft: Story Mode, and was never intended to appear in the original game.
As it stands, there is no way to summon a Wither Storm without the use of unofficial mods, such as the one Robbie mentioned in his answer.
Note that these mods may require installing an unofficial version of Minecraft, and they may only work in a certain version of the game. For instance, the mod that Robbie linked to requires the Forge mod loader, and it will only work in version 1.8.9, which has been obsolete since 2016.
I would advise that you take caution when installing mods into Minecraft, especially when you are using older versions.
