The Angry Video Game Nerd (formerly The Angry Nintendo Nerd and often abbreviated The Nerd) is the title character of the popular webseries of the same name portrayed and created by James Rolfe. In each episode, he reviews a different poorly made video game, foul-mouthedly complaining, overeacting and often shouting about either graphic and music quality or gameplay, but more reasonably the latter. His mortal enemy is the Nostalgia Critic.
Role in "The League of Ranters"
After seeing Gordon, Waffle, & Mr. Blik save the day for the 500th time, the Nerd mutates into Cycponerd, only to be defeated in battle.
