My Hero Academia: Web of Shadows

From the streets of Toronto to the cities of Japan, Zack Holt has lived an interesting life.

Born to parents who abandoned him after he developed no quirk, living and surviving on the streets of Toronto for two years before being taken in by his adoptive Mother.

She and Zack moved to Japan where the incident happens, a meteor crashes in the woods and being the curious child Zack is, he investigates.

Finding a symbiotic creature slithering on the ground, Zack does what every dumbass does in Hollywood and holds his hand out to it.

From there, Zack and (eventually named) Venom roam the streets of Japan as a vigilante, well, sort of.

That's the start of the story, this is eleven years later, and Zack is not some kid anymore
