Genos

Genos is a mechanical cyborg of average human height. His face and ears look like that of a normal human, made of artificial skin material, and his eyes have black sclera with yellow irises. He has spiky blond hair and his eyebrows are blond (brown in the anime). He also has pierced ears. Genos's wardrobe consists of street clothes with all of his upper-body attire being sleeveless as to allow his arms to transform without hassle. He has 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[4] and the arms he equipped to combat the meteor.[5] Sometimes the arm sets he uses create a metal framing around his face, like when utilizing Arms Mode. Genos is an extremely serious character, rarely if ever making jokes. He constantly aims to become stronger and frequently looks to Saitama for advice to achieve his goals. Since becoming Saitama's disciple, Genos is very reverent and protective towards Saitama (who he refers to as "master"). Genos envies and reveres Saitama, although this does not stop him from expressing annoyance and disbelief at the mundane training regimen Saitama used to gain his powers. Genos is an intense person, unyielding in his pursuits. Before meeting Saitama, he was even more intense but Saitama has been a moderating influence on Genos, helping him to be calmer and take a more measured approach to his pursuit of justice and power. Genos realises how far he's come when he witnesses Sweet Mask dispatch a group of alien prisoners without mercy and remarks how similarly hard-hearted he used to be himself.[8] Genos has slowly become less serious and becomes a bit curious about some minor things such as the meaning of fun. He is also able to lift a truck with a single hand without difficulty.[24] During his brief fight with the Deep Sea King, he was able to land a full-force punch on the creature that sent it flying through the wall of the safety shelter. Genos is very agile and can move so fast that he appears to be teleporting. He was able to keep up with Speed-o'-Sound Sonic for a considerable amount of time in their battle, with both of them moving faster than Fubuki could see. Genos's body is almost completely artificial and does not have the same vulnerabilities that completely organic beings possess. In conventional terms, he does not experience fatigue since his performance and abilities are contingent on the condition of his cybernetics, the energy supply in his core, and the energy output of his core. His body is constructed from highly durable materials and can only be damaged when external forces surpass the limits of those materials. Genos can continue fighting without much drawback even with portions of his body missing. As he lacks blood or vital fluids, he is immune to blood loss, and his neural connections to his cybernetic body differ from those of normal humans, rendering him impervious to shock or its inhibiting effects. He has demonstrated the ability to fight and move even after his limbs have been torn off on various occasions. Due to most of his body being artificial, he appears to have an extremely high tolerance to injuries due to him not being able to feel pain for the most part. However, it can be inferred from the expression on his face after coming into contact with the Deep Sea King's acid spit that he is susceptible to pain caused by direct acidic corrosion on his body. Apart from this, he seldom displays significant signs of physical stress.
