Currently under a rewrite (sorry to those who enjoyed the original story but I was not happy with what I had written.) Bat-Man's second apprentice is dead. A new vigilante wants blood. Gotham is under siege. (I don't own marvel or DC. Just the fan fic.)

Teaching others to become the next best heroes is a good alternative. Random 'experiment'

Izuku Midoriya has always wanted to be a hero. But the death of his childhood friend at the hands of a villain, and his idol denouncing his dream, his faith in himself and this hero society has been shaken to its core. But one man still sees his potential and takes him under his wing, or batwing as it were, and teaches him that he can be a hero, even without a quirk.
