Quentin Beck

Quentin Beck, AKA Mysterio is a powerful individual who has the ability to travel throughout multiple dimensions across the Multiverse in order to protect them and keep Multiversal Chaos from occurring across the space-time continuum.

However, that is just the falsified pitch that Beck sells whoever he wants to scam next. No matter what the situation or the time period, Beck is always trying to cause enough trouble throughout the Multiverse that the previously-mentioned "Chaos" will eventually happen everywhere.
