To ordinary bystanders, she is a rich ojou-sama type, proper and graceful being a student of Tokiwadai, a prestigious all-girls school. To those who knows her like Shirai Kuroko, Saten Ruiko, and Uiharu Kazari, she is in reality very short-tempered, have tomboyish tendencies and most of all prideful.

Misaka Mikoto's signature move. Mikoto can fire metal objects at three times the speed of sound by forming parallel currents on both sides of her arm with her esper ability. Each shot can reach the speed of 1030 m/s (2307.2 mph). She can fire 8 shots per minute. Misaka mentioned herself that she can fire more 8 a minute, but it is yet to be seen. Misaka's firing range is 50 meters (+-) when using Arcade Tokens.
Mikoto can launch a lightning attack regardless of the prevailing weather condition.
When she fought Touma because of a misunderstanding, she uses a Lightning Attack that cause a massive power failure in Academy City.
She can also launch a Lightning Strike generated by her body without using the atmosphere.
Powerful Electromagnetic Pulse
Mikoto can release a powerful electromagnetic pulse attack (EMP) that can disable machines
Also, her EMP attack can be used to destroy a living opponent's internal organs.
Mikoto can use electromagnetism in launching offensive attacks as well as defensive actions. She can attract metallic objects and use it as projectiles or using the same as a shield to defend against attacks.
She can also use electromagnetism to walk on walls and ceilings by attracting the iron particles on the surface.
Iron Particle Whip/Sword
With her strong magnetic powers, she can attract iron particles and sand in her surrounding and fashion them like a sword. Mikoto can also make them vibrate to further the swords cutting power.
If the opponent is out of reach, she can lengthen the make shift sword and make it act as a whip.
Mikoto can use her powers to gain access to computers and easily bypass security protocols by using her electric powers.
She can extract information from any device and can even erase herself from a live video feed.
Electro Magnetic Sensory Perception
Misaka's powers allows her to sense electric, magnetic, and electromagnetic phenomena. Similar to animals who can use this type of sensitivity, like birds using the Earth's magnetic field like a compass, she can tract anything that emits or generates electromagnetic waves/signal.
Also, Mikoto can release electromagnetic waves around and generate a 3D image of the location she is in if ever her vision is impaired.
All Espers before using their power needs to calculate everything for them to use their power effectively. Using the formula similar to her Iron Sand sword, if surrounded by a large amount of atomized water vapor, she can manipulate the water vapor forming it into wings using the static electricity from interactions between particles to fly.
Since telepathy is controlling the electric synapses in one's brain. Misaka can defend herself from this attacks by electromagnetic barrier created by her AIM Dispersion Field.
Her barrier is said to be always on and acts automatically.
