- Both have been "experimented" on

Accelerator

Equipment

Choker-style electrode: After he was shot by in the head, Accelerator, despite having survived, had his frontal lobe badly damaged and lost his ability to walk or use his motor skills, as well as his verbal and calculation abilities, preventing him from properly reading and speaking. This unique electrode, which is attached in his head, connects him with the Misaka Network and thanks to the limited connection to the brainwave network he has gained enough calculation ability to think normally, understand and speak, walk, etc. The choker has three modes: off, normal mode, and esper mode, where the battery runs out in 15 minutes after entering this mode. This was later modified to 30 minutes, but it was also tampered with at the same time with a safety device that allows for someone to remotely prevent the device from switching to esper mode.

Modified crutch: The crutch Accelerator always uses to support his body when he is in normal mode contains a small motor and weight distribution sensors that allows it to determine Accelerator's center of gravity. Instead of ending a single leg like a regular crutch, it ends with four legs attached to the end like a microphone stand, which, according to the narration, "holds the ground" helping Accelerator to get up when he is down. The staff along with the four legs can be retracted in and out of the cuff. However, its more important feature is a component inserted by Accelerator that blocks other interference devices. The crutch allows for Accelerator to block specific wavelengths after successfully analyzing it and, using the equipment in the crutch, generate an interfering wavelength specifically engineered to block the original wavelength.

Abilities

High-level Intellect: Accelerator has shown frequently to possess a very high intellect. For starters, his esper ability is shown to require complex calculations to function, with him being skilled enough in this field to come up with a new application on the fly during his battle against Touma. He also appears to have a very good memory, as he memorized the codes for Last Order's default mind state and was able to remotely return her to that condition, thus erasing the virus planted into her by Amai Ao. Later, he also starts to display clever strategies in battle, as when he was able to take out the Hound Dogs using firearms, which he utilized for the first time against them, along with exploiting his immediate environment and his enemies' psychological state to his advantage, without using his esper ability. Even with less than half of his calculation ability, it is great enough to allow Accelerator to calculate and analyze all the 25,000 different kinds of energy of Kakine Teitoku's Dark Matter, while fighting on par with him and protecting bystanders. Finally, he was able to figure out a way to block the signal used to shut off his electrode and to figure out ways to diminish the harmful influence magic has on his body as an esper, which is a feat only one other individual has accomplished so far. He is also fairly skilled at identifying spies; as well as being a skilled interrogator, as he was seen to easily break a Russian spy with Misaka Worst's help.

Machine Ingenuity: Accelerator is also quite competent with machinery and technology, evident in when he modifies his cane with various gravity sensors and small motors to help better support himself. He also implants in it a mechanism to overcome the Board of Directors and their subordinates' means to shut off his choker-style electrode by memorizing the wavelength they use and blocking that wavelength afterwards.

Marksmanship: After his fight with Kihara Amata, Accelerator realizes that he can't consistently rely on his power. As such, he trains with firearms and is shown to be extremely proficient in their usage. With his left, weaker hand, he is able to finish off a round of practice in 70 seconds. He commented that his reloading of a pistol in two seconds with just one hand and his teeth is too slow, even though he was simply testing the gun.
