Genos

Genos, is a 19 year old cyborg and a self-proclaimed disciple of Saitama. He is always aiming to become stronger and fights for justice. As a registered Superhero, he is in the S-Class, at rank 14. Genos has a mechanical body which is a model of a teenager, a pale looking face, yellow eyebrows, black sclera and yellow piercing eyes and has blond spiky hair. Over his mechanical limbs, he wears black pants and black shoes, and he also tends to wear tanktops. Genos has been shown to have many different sets of arms, with varying abilities and strengths. Notable examples of his various "arms" are those he used in his sparring match against Saitama and the arms he equipped to combat the meteor. The pair he used against the meteor had an interesting effect of changing not only the appearance of his arms, but creating a metal "framing" around his face.

Genos is an extremely serious character. He constantly strives to become stronger and pesters Saitama to train him frequently. Since becoming Saitama's disciple, Genos is very reverent and protective towards his "teacher", although he does express annoyance and disbelief at the mundane training regimen Saitama used to gain his powers. On most occasions, Genos acts as a comic foil to Saitama's clueless antics, using a variety of special techniques, battle tactics and robotic upgrades to combat villains (and sustaining terrible damage in the process), only to be outclassed by Saitama with a single punch. Despite their disparity in strength, Genos' diligence earns him greater recognition than his mentor. His superior acumen granted him immediate status as an S-Class Superhero within the Heroes Association, compared to Saitama's C-Class designation. He also possesses seemingly vast wealth, enough to repair or upgrade his cyborg body and cover Saitama's rent on a regular basis. He eventually mellows out, and he recognizes that this is due to Saitama's influence. He eventually comes to respect Saitama not just for his power, but also for his character. This was shown when Genos remarks on how similar Handsomely Masked Sweet Mask is to Genos's former self when Sweet Mask brutally dispatches a group of alien prisoners with no mercy. At age 15, Genos was still a human being living a happy and peaceful life along with his family. One day, a crazy cyborg attacked their town and destroyed it, killing his family. Genos miraculously survived, but he wouldn't survive long alone in his ruined town if he wasn't found by Dr. Stench who passed the town pursuing the cyborg. Genos begged Dr. Stench to transform him into a cyborg, who complied and he was reborn as a cyborg fighting for justice and promised Dr. Stench that one day he would find and destroy the cyborg. For the next four years, Genos traveled from town to town defeating monsters and evil organizations, but was unable to find the whereabouts of the cyborg. Core: Genos' cyborg parts are powered by an orb in his chest labeled "core," presumably designed by Dr. Stench. Genos has shown to be able to put his core into the shoulder of his arm, throwing all of his energy into his heat beams.

Genos's entire body has been replaced with combat-ready cybernetics and prostheses, giving him an extreme level of strength and speed, as well as advanced sensors and projectile attacks. For someone his age, Genos also has significant battle experience, as he claims to have defeated countless evil entities and organizations before meeting Saitama. His youth and impulsiveness still overcome him on occasion and he remains much weaker than Saitama. Super Strength: Genos's android body parts are easily capable of breaking steel and shattering concrete. His strongest technique displayed thus far is Machine Gun Blow, an attack of rapid-fire raining punches strong enough to shatter a cliff face. Super Speed: Genos displays impressive speed across distances. He was actually capable of outrunning his own heat blast and tackling Saitama with enough force to hurl them both into a cliff face before it could strike. His control over his speed is somewhat less 'refined' than his teacher's, as his powerful robotic legs tend to shatter the ground with each step when moving at high velocity.  Armor and Replacement Parts: Genos gains not only incredible durability from his armored body, but also benefits from the nature of robotic equipment itself. Genos can lose limbs or have his body torn asunder, only to return to perfect 'health' through replacement parts and repairs (the source of the replacement parts is unclear). As an android, Genos does not seem to feel pain, and can keep fighting even when missing limbs or injured severely. Genos's durability is such that despite taking several powerful blows from Carnage Kabuto, and having one of his own powerful blasts reflected at him, he was still conscious and able to stand and walk. Heat Beams: Genos's palms contain ports which allow him to fire large and powerful blasts of heat or flame significant distances. A blast from his palms was powerful enough to obliterate a multistory building which was the base of House of Evolution. Later, while sparring with Saitama, Genos reveals cannons built into his fists and arms which can produce even stronger blasts. Genos has also been shown to be able to reduce the power of his blasts to a warm breeze, which he uses to dry dishes. Sensors: Genos's android body contains a number of passive and active sensors which allow him to scan the environment for enemies, both during active combat and while scouting from a distance. The sensors are not perfect however, as they can still be fooled by the extreme speed of an opponent like Saitama, and their Usefulness is limited by Genos's reaction time. Anti-Saitama Tactical Arms: These are a set of replacement arms Genos used during the National Superhero Registry Arc when Genos and Saitama sparred in the quarry. These arms are differentiated from his normal arms by being black, having much larger shoulders, forearms and fists and generating a glow between the plates of metal and having his eyes go white when active. The fists and forearms of these arms open to reveal several guns. The beams generated by the guns are significantly larger that his normal blasts and are characterized by smaller individual beams circling the main beam. If he puts both of his fists together the resulting blast is massive, much larger than that of one arm. Arms Mode: A prototype weapon system that Genos possesses. When inactive it takes the form of a suitcase. To activate it, Genos pushes a button on the handle and then throws it in front of him. The suitcase splits down the middle and separates, each half then opening revealing the "arms" inside with the container then flipping back to become the attaching mechanism. Genos then throws his arms into the new "arms" and they attach to him causing quite a bit of electrical discharge. When the "arms" fully attach, parts run up his shoulders and neck and his face is framed by pieces of metal. The new arms are much thicker and are all black, with the blaster on his palm having changed shape as well. While using these arms, Genos was shown to be able to move his core to the shoulder of his right arm, directing all of his power into a massive blast.
