Green Arrow vs Boomerang

And now, for the 'Spiderman Villain' versus 'Justice Leaguer'...

Fred Myers, Australian, former baseball player, with a knack for using anything 'throwable' as a weapon; if he can hold anything in his hands, it's almost sure he can use it as a deadly accurate projectile. His favorite weapon, of course, is the boomerang; his weapons are modified for a multitude of effects, and his suit has jet boots for extra mobility. The combination of long-ranged attacks and flight had allowed him to battle Spiderman, and even survive a fight with The Hulk.

His opponent? Oliver Queen. Green Arrow. A master archer who, like Fred, tends to modify his 'projectiles' for several effects.
