Let's Play a Game

What's your least favorite champion in the game and why? Not just this current meta's OP champs, but champs who every time you see them played your eye starts twitching and you see red. I'll start: Mine is Heimerdinger. HE JUST F*CKING SITS THERE SADGFIEGFRKGHIYOTH..... ahem. sorry. I just hate him with a burning passion because he can be so dominant in lane by doing nothing by sitting there in a little bubble of towers. You cant engage on him without stepping into them and being instantly half healthed, and if you try to destroy them without taking damage you're using your mana to do it, while he just puts another one in and then has no more mana expenditures to deal with so he's never mana fucked. Some of the most one sided, boring lanes i have ever played against and i would not wish a heimer upon my worst enemy. Who is YOUR least favorite champion?
