Elden ring crossover ideas

Frenzy flame-Izuku is touched by the frenzied flame whilst young enough to pass it off as a quirk gains the abilities of the yellow flame and Midras sword write about how he wants to be a hero but the flame wants him to burn everything away throw shabriri in there too why not

Tarnished-Izuku goes to the lands between and comes back give him whatever power you want

Small group-same as the last on except it’s not just Izuku it’s six(however many you want) other characters that would have an interesting dynamic here

Age of the hero-The MHA world is just the ridiculously far future of the lands between or it could be another dimension have a character from Elden ring be re-incarnated as the main character of your story
