By Green Lantern's Light: Emerald Dawn

When All Might told Izuku Midoriya that it was impossible for him to become a hero without a Quirk, the green haired teen thought that was the final nail in the coffin of his dreams. Unbeknownst to him, fate had something a bit more cosmic-oriented in store for the boy.

Crashing on the veritable junkyard that is the Dagobah Beach, the legendary Abin Sur passes away, bidding his ring to find someone to succeed him, leading the ring to place itself right onto Izuku's finger. Now a Junior Member of the Green Lantern Corps, Izuku is able to finally make his dreams into reality (and maybe win the heart of a very pretty rich girl with a construct ability similar to his own) by becoming a student in the Hero Course at the prestigious U.A. Academy.

However, not all is well for our newly-minted Emerald Knight. On top of the dangerous collective known as the League of Villains and the deadly enemies both terrestrial and extraterrestrial that he faces as a Green Lantern, none are more dangerous than the Red Lanterns and the Sinestro Corps... and, thanks to young Midoriya, they've turned their gaze towards Earth and the possibility of new recruits among those who call the planet home.
