Ghetsis

Ghetsis (Japanese: ゲーチス Geechisu) is one of the executives of Team Plasma. You first meet him in Karakusa Town where he is giving a speech to the locals about how you shouldn't enslave Pokemon. Ghetsis is described as having a bitter and look-at-me type of character. His son is N, as he specifies while lecturing him about losing to you.

In the games
During your quest, you find Ghetsis numerous times telling everybody to send their Pokemon to Team Plasma to be released back into the wild. Ghetsis's motives are different from that of N's because N understands Pokemon and supports them with a full heart. Around the end of the game, when N was defeated Ghetsis appears and says that the once impressive leader was a disappointment for losing to you, and then reveals that he was using him all alone just for his own needs. After saying this he thinks that N is a pathetic Leader and should be banished from Unova forever, he then challenges the player as the final trainer of the game (excluding their being a Champion in the main game and counting his absence post-game). Despite his strong team of Pokemon, Ghetsis loses to the player. After that, he is taken away by the Champion Adeku and Cheren.
