@ArkoSalminen@its_The_Dr A gun, by definition, is a weapon. It's not like knives that can be used as a weapon but has other uses. Literally all guns were made to kill. Your argument against ARs specifically doesn't make sense.
@Familiar_Assist I hate the "he can't emote" excuse. HE'S FUCKING BATMAN! The only emotion he wants to convey to criminals is "I'm pissed. You're fucked." His default look is a scowl. He should always look mad. The animated batman in this post is an example of one who almost never emotes.
@SymplyTonbra You're only supposed to get your tattoos once you've proven that you've mastered airbending. Aang was the youngest to ever master it which is why he got his so young. He's an exception.
