Scarecrow's revenge against Batman
Its Bruce Wayne's Birthday and Bruce has set up a big party in the ball room at Wayne manor. over a 100 guests have arrived including Diana, Clark Kent, Grayson, Hal Jordan, and Cassandra Cain
Scarecrow finds out about Brucey's party and decides to crash it. He looks online and see who all has been invited to the party. Scarecrow has done a little heavy research on Clark Kent and has spent a week coming up with some Special Gas for him. So instead of using the gas on batsy why not spray some on Clarky and use him as the weapon against Bruce and everyone else at the party ?
Scarecrow arrives at the party disguized in a nice ol tux as one of Bruce's old partners. Scarecrow walks in and starts talking to some of the folks in the party, then he finds Clark and talks to him for a min. Clark comments on Scarecrows cologne, and Scarecrow says why Thank you, here you go have some for yourself. Bam Clark gets sprayed.
What happens from there ?
