The most annoying game character EVER would have to be Navi from The Legend of Zelda. I mean c'mon I don't need you to point out the most obvious things. But the thing that pisses me off the most is the only three words this fairy was programmed to say, HEY, LOOK, LISTEN.
HEY, LOOK, LISTEN you f***king annoying fairy I'd rather be forced to listen to constant Katy Perry. (Smosh reference)
Like seriously, PLEASE just please for once, just help me out with something I actually can't figure out on my own. I'm sorry you think I don't have even enough common sense to find the most obvious things in the game. But sir, you must know that I indeed exceed your mental capability expectations.
