VIP2001
For powers you can make him use his electricity to control magnetism like Magneto from X men. There’s also Enel from one piece where he can make his body out of lighting to avoid physical attacks. Lastly, theirs Naruto with the Raikage making an armor out of lighting which grants near invulnerability, and piercing like buff to his attacks. Also with nobody ever able to pierce the armor expect the user himself when he accidentally attacked himself.
I only know of one other fanfic that decided to use the electric dude as the main hero but this is so much better. Unfortunately the other fanfic decided to keep the WORST part of the MHA series... the constant crying aspect of heroes (even if its true that the quirk is affecting the dudes emotions its irritating to read)
