I think the wither storm SHOULD appear on a possible sequel of the minecraft movie because well,why not?,i mean the wither storm IS the perfect boss for a sequel and since the minecraft movie adds original stuff like that one golem with the boots of swiftnes,the big pig (or whatever its call) and the potato luncher it could be great that the wither storm had unique sutff too,for example:The wither storm will be able to control mobs by using some sort of parasite or something similar like the sculk,being able to create its own creatures,control the world since the wither storm has a command block as a heart and probably have more attacks other than those fireballs and that purple light from story mode and i might be crazy if i said this but the wither storm should also have A VOICE ACTOR,i think if the wither storm had voice the head of the middle should sound like minos prime from ultrakill but with a REALLY deep voice,the left head should sound like AM from i have no mouth and i must scream(the game) and the right head should sound like weathley from portal
