N

N is Jimmy's rival and the king of Team Plasma in Gen 5 (Pokemon Black).

Prior to Black's Start
Even before Black started, during the last few hours of the Intermission between HeartGold and Black, memes already began to form surrounding N due to the repeated playing of the Pokemon Black title menu. In the title menu's animation sequences, N is shown being crowned. Because this happened repeatedly over the course of several hours, jokes were made surrounding the number of crowns N has.
