Help. I need recommendations

Izuku Midoriya has a quirk. It allows him to open one way portals to different dimensions... except, it's not him who goes through them. It's people from other dimensions. Not only can he open portals, he can also use the powers from other dimensions.

Unfortunately, he has no control on the portals opening and when he gets One for All, it activates bringing hundreds of people from other dimensions into his own. It also awakens his other dimensional powers. How will Izuku and his new found allies beat enemies from other dimensions?
