Batman
That actually happened on Cartoon Network once.
Captain America's shield is nondestructable. Green Arrow could try to kill America but America would have Hawkeye with him.

Hawkeye
Yes
That battle would end in a draw since good only triumphs over evil.
Batman Batman knows every secret and weakness of every superhero. He already knows how to beat Green Lantern if they had to fight.
Green lantern
2 superheroes that have no powers are Batman and Green Arrow, they are both human heroes but Green Arrow uses special arrows for his fights whereas Batman creates all of his special gadgets using his money and smarts.
Batman's best friend is either Superman or Green Arrow. Green Arrow (to my knowledge) is the only other Justice League hero without supernatural powers, and through this they seem to have a sort of understanding. Superman, however, is often shown working with Batman.
Contributor opinions:Batman would win.
Hawkeye saw Green Arrow with Loki, Thor's brother. Hawkeye and Thor went to fight Loki. But they saw that Green Arrow was helping. "That's enough, green arrow man, you give up working with Loki." Thor threatened. "Justice is served, Thor." Green Arrow said. Green Arrow knocked Thor out. Hawkeye defeated Loki but Green Arrow struck him in the arm with an arrow. "Give up! I am Hawkeye." Hawkeye yelled. "Well, you are a crusader. You give up!" Green Arrow taunted. They began fighting. Hawkeye saw that Thor came back. "I remember you, Arrow boy! I am Thor!" Thor taunted. "And I am Green Arrow. You want to know about me?" Green Arrow teased. Thor took revenge for Odin. He killed Green Arrow and put Loki to jail.
