The description of Genos (ジェノス, Jenosu) Free 2D Anime Battle Game
Genos has an entirely mechanical body in the model of a handsome young man. His face and ears look like that of a normal human, made of an artificial skin material, and his eyes have black sclera with yellow irises. He has spiky blond hair. His eyebrows are usually portrayed as blond, but in the anime they are brown. He also has pierced ears. Genos wears normal street clothes and sleeveless tops and hoodies in order to allow his arms to transform without hassle. He 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. Sometimes the arm sets he uses create a metal framing around his face, like those he used against the meteor and the Deep Sea King.
During his fight against the Forest King, he upgrades his body to have his energy core exposed in his chest and his arms are imbued with a rocket-like engine.
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. Due to Saitama's incredible strength, Genos is led to believe that there is a secret to Saitama's power.
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 Hero 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 Sweet Mask is to Genos' former self when Sweet Mask brutally dispatches a group of alien prisoners with no mercy. Genos slowly becomes less serious and becomes a bit curious about some minor things such as the meaning of fun.
Surprisingly, he is rather disrespectful to those who constantly interrupt Saitama or constantly pester him, as whenever Bang or Fubuki command him or attempt to recruit Saitama, he will continuously tell them to get to the point, and will defend his position as a disciple of Saitama, and nothing else.
Genos appears to have a certain sense of pride in his abilities and himself. This is seen in his battle against Awakened Cockroach when he shows slight disappointment in having to use the adhesive material, as it would force Genos to accept there were monsters much faster than him.
Despite his confidence and faith in Saitama's limitless strength, he cannot fully comprehend the true power of Saitama since he thinks Saitama will need help to defeat some powerful monster that Genos himself cannot defeat. The prime example is Gouketsu. However, unknown to him, Saitama always come out victorious without any scratch from his body.
Genos was also a serious person before he became a cyborg.
Abilities and Powers
As a S-Class hero, Genos is undoubtedly a powerful fighter. 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. However, despite his amazing growth, he is still unable to fend off against dragon level threats.
