Since then, he has also gone on to win the AAA Mega Championship. Dom has done everything possible to cheat his way to victory during his matches.This week on WWE RAW, Dom defended his Intercontinental Championship against Penta.

There has been a lot of praise surrounding his performances as of late.During an episode of RAW Recap, Big E backed Dirty Dom to win the World Title in the future."The thought of putting the label ‘future world champion’ on Dominik Mysterio three years ago, four years ago, [was] laughable. I’d laugh you out [of] the building. But now, is this outside the realm of possibility? Not at all. In fact, I would be surprised if Dominik Mysterio doesn’t hold a world championship within the next five years," he said.It will be interesting to see if Big E's prediction about Dominik will come true.
