So i had this funny idea, how would a superhero use a gun when they found one
Thor: Doesn't know how to use a gun. Shoots himself then throws it away
Hulk: Uses the gun like a club, smash you until you die and continues smashing until the gun is smashed.
Iron Man: Uses the gun like a gun. He might think of remodeling the gun, giving it a new look.
Black Widow: Uses the gun like a gun and a club. How? She is badass, deal with it
Captain America: Uses the gun like a shield.
Hawkeye: 'Guns are for weak. Men use arrows' is his motto. Brings 11 arrows on every occassion
DC Justice League:
Superman: He finds the gun, but doesn't use it. Instead he crushes the gun so no one can use it.
Batman: Finds the gun, analyze the gun to find it's user. Tracks him and stops the illegal supply of armory and hands over the guns to the cops. He is the boss
Green Lantern: Uses the gun with his power ring. Showoff is required right, After-all, he has the most powerful ring.
Wonder Woman: Uses the gun like a baseball bat. Well it's the best way she can use it
Flash: Opens the gun, takes out the bullets and throws them faster at his enemies.
Cyborg: Assimilates the weapon into his "system".
