The Nintendo character Luigi used to be so happy but then something changed, something deep inside. He hasn’t been the same since.

The dark side of Luigi has been making headlines around the internet this week. Collections of death stare gifs and videos are going viral as we speak. If you have been wondering why the internet was slow this week it was all Luigi’s fault.

The quirky behaviour that has captured the world’s attention is nothing more than a facial expression, but this is no ordinary glance it is a death stare. In certain situations in Mario Cart 8 Luigi will glare at his foe with a death stare worthy of the hardest gangster. All of this attention has quickly made Mario Cart 8 the Wii U’s fastest selling game, selling 1.2 million copies since its release a week ago.

Presented for your viewing pleasure is the ultimate compilation of Luigi death stares, the plumber with attitude doing his best to menace the competition. Sit back relax and remember to never ever make eye contact.
