meeting the bat

Hello and welcome back today to y/n x Batman I hope your gonna enjoy :3 *pic above is your super hero outfits just the outfit is important*

Y/n p.o.v
Me and Harley worked all day on a hero costume that look legit real your super hero name was diamond star and you had quike reflects and were helpful as your brother explained to you lucky you were a skilled fighter so non of this would be a problem to play along with it later that night you were ready you changed in you costume your bracelets were filled a sort of glowing glue so when you hit a bottom it would shoot and get the person stuck in it you were waiting for your qeu to come out that's when you heard the alarm go off of a bank nearby you quickly climbed up the room when you saw your brother there and winked at you put on a smirk and nodded then you heard a woosh behind you you knew exactly who it was " well well well look it's batsy! Sorry batsy I'm kinda busy here with miss star!" He said and laughed she growled " tss joker you should by now know never to underestimate a girl " You said and a with a few clicks on your bracelets you shot at joker whole crew getting them stuck leaving joker alone keeping his smile up " hahahhahaha!!!! Come and get me stary!" He said before running off and you following him leaving the bat and the boys kinda surprised behind they soon followed you two though seeing you fight the joker and defeating him easily tieing him up and trew him at Batman "hehe easy " You said while dusting your shoulder off " who are you and why are you fighting the joker?" Batman asked you you looked at him and smiled " my name is diamond star and I fight him after all the things he has done I toughed and gave you a little hand " You said winked at Batman and runned off

Thirth view
Joker whistled at Batman "haha looks like miss star likes you " he said while winking at the bat who just grunted and left the joker their as the cops came and handed him over when the bat boys came home dick grinned at Batman " You know joker was right she seemed to like you~" dick teased his father "yeah plus she is also a hero maybe you should get to know her better" Tim said "how can you know it wasn't fake she just appeared out of nowhere" daimen said looking at his brothers who looked at him weirdly " daimen is right she just appeared and took joker out easely " Jason added bruce was just watching his sons "we Will just need to keep an eye out on her " he said while turning to his bat computer showing y/n jumping from roof to roof doing some tricks meanwhile that night left bruce wide awake thinking about the diamond star and what she really was and why she was helping him
