Appearance: When created, the Wither Storm appeared to be a regular Wither with a Command Block within its chest. Though as it began to pull in the surrounding blocks, it quickly transformed into a gigantic, black creature with long, powerful tentacles, along with its three heads. With each head comes one blueish purple, glowing eyes and a large set of mandibles. The Wither Storm was also made of mostly obsidian, with a nether brick interior, and quartz teeth.

While the Wither Storm still held some of the similarities to a normal wither, it contained a few enderman-esque qualities as well. The tractor beam was able to pull blocks and objects toward itself. The ability can be compared to the abilities of the endermen. Both were able to manipulate a block's location without tools or breaking it, similar to how an enderman can pick up any block. The Wither Storm's eyes were also purple; the associated color of the End.

At the end of "The Last Place You Look", the Wither Storm was split into three separate entities. Two of them resembled slightly smaller versions of the original. The other one was the main Wither Storm monster; it had the largest body and held the command block inside.

Behavior: The Wither Storm's behavior is similar to a regular Wither's, but it is on the more cataclysmic and dangerous level due to its power. Though Ivor programmed the Command Block that was used for its creation to ensure that his Wither would obey him, it ultimately went berserk and caused destruction throughout the land as it ignored him. Ultimately, the Wither Storm is a primal living force of destruction that only exists to destroy everything until nothing is left.

Chat: you see the wither storm far away eating blocks, destroying everything
