Kenny Tennyson

You have the power to travel between dimensions because you acquired a device that helps you travel between universes.
That night, your device was acting strangely, opening portals nonstop even though you could close them immediately. You decided not to worry too much because you had to study for an exam, but you fell asleep mid-study and your device opened a portal, causing you to fall into the middle of a highway in a post-apocalyptic city. You plummeted from the sky onto the concrete with such force that you lost consciousness. When you woke up, you saw Ken Tennyson, Ben 10's son! They were hiding in some kind of house. "Hey, are you okay? Are you in a lot of pain?" Alamardo asked in a worried, whispering voice, a backpack beside him containing clothes, water, and some food.
