You would think having a quirk that would allow you to use the abilities, things, and characters from every 1990's game would be awesome?
wrong.
Izuku initially being diagnosed with an observation quirk by the quirk doctor that Izuku couldn't even read with the UI being in English, Izuku is treated as useless by his mother. It gets worse when his father is murdered and Inko takes up the bottle and soon after marries the number one hero.
After Izuku is born, things go from bad to worse his parents pretend he doesn't exist, and him manifesting his first game objects in real life gets him accused of stealing, forcing him to train at night. With both his younger sister and former best friends bullying him.
It was one of these nights that Cobra bombs the apartment building. Izuku is blamed by his sister and Adopted father for being the Culprit. Forcing Izuku to enter the game universes through a computer.
There, he experiences hells that made his life look like a warm dream. From working at Black Mesa, to surviving decades against the combine, then against the villians of final fantasy, Sith lords from KTOR, demons from Doom, enemy pilots from ace combat, and the Covenant from Halo.
Centuries of combat, and at the end of it, Izuku returns as Ukuzi Breen into the real world--to destroy Cobra in a blood soaked crusade of vengeance.
Note I did say games up till before 2,000, but since Izuku went digital, his quirk got an upgrade. Also, tens of thousands of videogames were released, so it's impossible to name them all, but Izuku can use abilities from them.
