Cypher is now dead, and he is generally remembered as having the lamest mutant power ever conceived by the geniuses at Marvel comics.
This is all wrong.
Cypher's power makes him arguably one of the coolest and most powerful people on the planet. After all, from early on it was established in canon that his mastery of languages included all forms of communication -- verbal and nonverbal. Human beings give off thousands of unconscious signals all the time: body language ranging from posture to eye dilation, choice of diction and inflection, and just plain flop sweat. Cypher's power gives him the ability to instantly and accurately read all of these signals.
What would this mean in the hands of a creative writer? Well:
- He is a perfect lie detector.
- He is the ultimate poker player.
- He is the ideal politician. In any political negotiation, he automatically knows where you stand, who you represent, and what you want to hide. In any political interaction, he knows exactly how you are reacting to what he is saying, and can change his behavior accordingly.
- He is an unstoppable businessman. He will win any negotiation. As soon as he sits across a table from you, he knows exactly what your bottom line really is -- and exactly what you want him to think your bottom line really is.
- He is the greatest lover in history. Every shudder he interprets perfectly. Every gasp is perfectly judged in how it relates to pressure, friction, and duration. Based on eye dilation and heart rate he knows if he should go faster or slower, wetter or dryer, looser or tighter.
