Technology has always played a major role in superhero comics. Sometimes the tech makes the hero, like the often upgraded suits of armor worn by Iron Man. Other times it can benefit a team of do-gooders, like the rings used by the Legion of Super-Heroes that give its members, whose adventures are set in the future, the ability to fly.

But the true heroes-behind-the-hero, one could argue, are those keyboard surfers who type furiously at a terminal and provide critical information to whoever they are assisting in the field. This special kind of tech support falls under the trope known as "the guy in the chair," but they are not always men; nor do they always help the good guys.

Professor X: Charles Francis Xavier, or Professor X as he is popularly known, is the founder of the X-Men, Marvel's mutant heroes who are often feared and distrusted by society. Professor X has often used a wheelchair and has led the X-Men from afar, keeping tabs on the team in the field with his telepathic abilities.

He has provided the team with some formidable innovations. The Danger Room, the facility where the heroes train in the use of their powers, started out relatively low-tech: an obstacle course with battering rams and flamethrowers. Another invention, Cerebro, was like a DNA test combined with Apple's Find My iPhone app: It can pinpoint the location of mutants and alerts him to the emergence of new ones.

Shuri: Black Panther's brilliant little sister made a big splash in the 2018 "Black Panther" film with her technological wizardry — Q to her brother's James Bond. In the comics, Shuri is similarly gifted but also more ambitious: She has her eye on becoming Black Panther, a ceremonial title of power and leadership in the advanced African nation of Wakanda. Shuri serves as Black Panther when her brother is incapacitated and later sacrifices her life to save him. But worry not: He finds a way to bring her back, and they fight side by side today.

Shuri is very much a field operative in comics, and she's responsible for creating an array of gadgets and gear, including a spaceship and nanotech wings (of which she boasts, "My latest success! Emergency flight in a can! I am awesome!").

Oracle: When Barbara Gordon becomes paralyzed after being shot by the Joker, her crime-fighting career as Batgirl might come to an end. Instead, Barbara trades in her cape, motorcycle and grappling hooks for a keyboard, various monitors and Wi-Fi to become Oracle, a genius-level computer hacker and information broker to the heroes of DC Comics. After undergoing an experimental surgery that implants a microchip into her spine to restore her mobility, she becomes Batgirl again but later decides that she has a wider reach as Oracle.

In a recent issue, her father, former Commissioner Jim Gordon, confirms that he knows about Barbara's other identities. After a heart-to-heart chat, she outfits him with a special satellite phone in his latest quest to apprehend the Joker. The phone is linked to Batman's communications system and is set to self-destruct if he does not check in on a daily basis.
