telekinetically manipulate peoples organs
[/quote]
The average human lung weighs about 2.5 pounds, the liver 3.2, the large intestine 4 pounds, the small intestine 3.5 pounds, and the brain 3 pounds. Now, a kidney weighs about a half pound, the heart is also a half pound, the pancreas is about 0.2 pounds, so you COULD manipulate those organs, but most other human organs of interest would be unable to be manipulated, so you'd be limited to how you could kill someone in that manner, and you'd have to perfectly emulate more natural organ failure, to successfully work as an assassin using this technique.

As for plankton communication: Become a supervillain by using the plankton to control the world's seafood production, commanding them to only breed at your order, thus controlling the population of all life in the ocean, and thus controlling a large aspect of global food supply, as well as other sea-based industries.

My next power: You can fly, but only in the four cardinal directions relative to your position(North, South, East, West), and to do so you have to accumulate special "flying points" which are scattered throughout the earth, with one point equalling 1 meter of flying distance.
