Bioelectrogenesis

Bioelectrogenesis is the generation of electricity by living organisms, a phenomenon that belongs to the science of electrophysiology. The nerve impulse is a bioelectric event. In biological cells, the Sodium-Potassium Exchanger maintains a voltage imbalance, or cell potential difference, between the inside of the cell and its surroundings (see also ion channel). Also called a pump, the exchanger is said to be "electrogenic," because it removes 3 sodium ions for every two ions of potassium it allows in. The process consumes metabolic energy in the form of ATP. Plant cells also exhibit light-induced electrogenesis. Certain types of bacteria are able to generate electric currents which are used in microbial fuel cells. However the term usually refers to the electricity-generating ability that is in some aquatic creatures, such as the electric eel and to a lesser extent the black ghost knifefish. Fish exhibiting such bioelectrogenesis often also possess electroreceptive abilities (which are more widespread) as part of an integrated electric system. Electrogenesis may be utilized for electrolocation, self-defense, electrocommunication and sometimes the stunning of prey.

In popular culture
The ability to manipulate electrical fields has appeared as a superpower in comic books and other works of fiction. In the movie Mr. North, the protagonist frequently creates static electricity shocks. In mythology, gods such as Zeus and Thor were able to generate lightning.

Some creatures in Pokemon, mostly the ones belonging to the Electric-Type (Including the franchise's mascot Pikachu and its trans-generational similars Pichu, Minun, Plusle, Pachirisu and Emolga) are able to generate and manipulate electricity at will.

In the video game BioShock, the player is able to rewrite his genetic code in order to create electricity with his body.

In the video game Infamous, the player has the ability to generate and absorb electricity which is known in-game as electrokinesis. This electricity could be expelled in a large number of different forms such as lightning arcs or electromagnetic fields.

In the TV show Heroes, multiple characters had the ability of electric manipulation. This allowed the characters to generate large amounts of electricity and use it at varying intensities.
