Basically I plan on doing a what if on my you tube channel(Blazing What If's) called what if Deku had a electro kinesis quirk (Lightning generation and manipulation) In it he will be a singer and it will be a harem and this is how the harem comes to be and how they find out about his secret idol identity. Izuku does have one for all, Only All Might knows about his secret Idol Identity. His Idol Identity is Tech.
