Geass a.k.a. Power of Kings (Code Geass)
Because every Geass power varies in abilities and limitations, I will be focusing of LeLouch’s Geass power (The power to bestow a command onto others) since he is the main character. It is by far and away the strongest power on this list; by looking into another person’s eye, the possessor of this Geass issues a command, and the person affected is under complete control to follow that command to the last detail, dipping into a state of lifeless idleness as the brain turns on autopilot setting a destination without any consent from the brain. An ability this overwhelming heightens the limitation to a onetime per person only kind of deal. Still, telling someone to "go die," "bring me $1 billion dollars," or "be my slave," has drives to make any person hunger for that power.
Death Note (Death Note)
A death note is a blank notebook. Seems harmless enough. Right? Think again, this isn’t a regular notebook that’s used in the classroom; this is a notebook in the anime world, where absurdity is the norm. Once the holder of the death note discovers that writing a name in the book kills that person within the next 40 seconds (of a heart attack if a specific death is not specified), it becomes a freewheeling weapon. The only pitfall, the holder has to have the image of that person’s face (i.e. seen that person before). Hence, the desirability factor of this power comes into play. Who wouldn’t want to kill an annoying neighbor, a betraying friend, or a douche boss, without a single hint of evidence traced back? Unfortunately, there is no such power, which is why this ability blindly coveted.
Super Saiyan 4 (Dragonball GT)
Super strength, super speed, supercharged kamehameha energy blast, buffer than Governor Schwarzenegger was in his heyday, long black spikey hair, and oh yeah, a pink tail. This is Superman’s real kryptonite, the ultimate exhibition of strength that will condemn even the strongest man to try, for all eternity even, to gather all 7 seven dragonballs just to wish to be the stronger than a super saiyan 4.
Invisible Hands (Elfen Lied)
A cyborg that looks like a human, and even has a brain to function like a human, is quite boring. But when you add invisible extended arms and inject those arms with massive amounts of steroids, coupled with an out of control cyborg; the result is hell razing destruction and a whole lotta fun.
Solar Hands (Yakitate!! Japan)
With this power, there will be no killing in the near f*ture, well…maybe if one is so inclined to heat up pastry dough and fireball it towards the enemy. At any rate, that is not the purpose of solar hands. What this is handy for is simply baking, baking bread to be precise. One may not conquer the world, but one does have the ability to conquer his/her hunger. Satisfaction guaranteed.
