The Avengers are about to face their biggest threat yet in the upcoming Avengers films. Kang teases the dangers and devastation of a multiversal war. Despite the Avengers having powerful individuals in their ranks, up to this moment none has the power level to defeat the time lord, other than one — the Scarlet Witch. There are many rumors concerning the inevitable conflict between the Avengers and Kang's variants. Going against such formidable foes requires a being that is equally, if not even more powerful, and the most promising candidate is none other than Wanda Maximoff.
