I don't care if these people aren't 'Pop Culture' because I do not subscribe to it. Anyway...
Evil INTJ side: One of my dominant personalities. He's completely immoral and cares nothing for human life, often cruel and vindictive. Very scientific and finds everything interesting and fascinating. Most likely to either take over the world or destroy it, if he had his way.
Most closely resembles: Caulder, from Advance Wars: Days of Ruin.
Caulder despises 'morals', which have prevented him from gaining understanding.
Rocket Scientist Without Pants INTP: The most dominant of my personalities. True to INTP nature, he's smart, learning-hungry, and forgets about the more 'basic' things. He doesn't eat like the rest of us, he eats without forks, they're a waste. Every one of his manners is to maximize efficiency. People are weirded out by him, but can't help but think he's a genius.
Most Closely Resembles: L, from Death Note. Certainly, he's able to pick up and process information at the speed of light. He's also able to formulate plans and derive information from all these processes. However, he sits in an odd way, and has funny mannerisms that, though weird, exude genius. He isn't that forgetful, though.
Whiny INFP: Emo side. He whines and groans all the time, and formulates strong opinions based on limited facts. Often slapped around by 'Caulder'.
Most Closely Resembles: Every one of those MANY whiny emos that are popping up EVERYWHERE.
Hyperactive ENTP: Hyperactive ENTP is the one who becomes very enthusiastic and loud, and often relishes the debate. He dedicatedly formulates ideas into words and spouts them out. He also is completely insane and will jump off the walls like a bouncy ball thrown at 100mph.
Most Closely Resembles: (Not Sure Yet...)
