EDIT: Wait...this question wasn't for Arkham Asylum, was it? Oops. My fault for not reading the question and category right...but I hope this helps if you DO play Arkham Asylum!
Well...bad news, you face Scarecrow multiple times. Good news, however, is that it really isn't a boss "fight," per se.
When you face Scarecrow, don't let him see you. EVER. Just move around the platforms (counterclockwise works best), and detonate any walls that block you. Use the bat signal once you're reached your destination.
Best of luck with winning!

No, it was cool to unlock Indiana Jones in Lego Star Wars, but you can't unlock Spiderman in Lego Batman. Star Wars and Indiana Jones are both Lucas properties, but Batman belongs to DC Comics and Spiderman belongs to Marvel Comics.
