Gysbert Don't be sorry man, Hawkgirl is pretty hard for Joker and you need to know exactly how tu punish her.
Use your d2 for breaking her wake up or you can jump and j3 + combos.
Use bombMB to break her zoning, and J3 + combos as possible. (j3, D2, db2MB, B3, j2, 32 flower)
I know this match up is hard for our mister J, but with pratice I am pretty sure you could win. Your Joker was nice and maaaaaaaaaaaaaaaaaan, you play Joker ! Be proud of it
No easy life for us and that's the fun point.
What about Cat ? He lost ? I haven't seen all the matchs unfortunately.
