The Oldest sister of the bats

How she came into Bruce's life no one knows she was just there one day . Athena is a smart girl and even though she isn't in the vigilante business she could kick the butts of probably half her family. This story is basically the webtoon Batman: Wayne family adventures but with my own character added.

I don't own any pictures or the characters expect for Athena.

English isn't my first language
