In Portal 2, the player meets Wheatley nearly as soon as the game begins. The somewhat surreal opening, full of staring at art and listening to relaxing music is interrupted by the introduction of his character; a nervous, happy-go-lucky robot that is saddled with the task of getting you to safety. The two of you are thrown together, an unlikely pair who must escape the wrath of the returning GLaDOS AI system, who is none-too-pleased about you killing her in the first game. Gulp. Good thing you've got your new best buddy Wheatley with you. Except for the part where upon giving Wheatley the power to achieve victory, the rush of such a thing he's been deprived of goes straight to his head. In a game that is often cited for its clever humor and witty script, the turn of Wheatley from ineffectual drone to a homicidal, killer machine is truly frightening. As you begin to realise that Wheatley now has complete control over the facility, your life expectancy goes down drastically. Being forced to team up with your old villain is a classic trope, but it works well here. Together, you and GLaDOS must combine forces in order to defeat the little robot gone mad. While it's difficult to say you find peace with your former foe, it's fair to say that the two of you will happily enjoy shutting Wheatley's big mouth together once and for all.
