Backstory: When he was a child, his town was destroyed by a cyborg who went on a rampage and his parents were murdered. So out of vengeance he asked Dr. Kuseno rebuild him bigger, stronger, faster, and tools to destroy this cyborg once and for all. Over the course of search, his drive for revenge has led to him a Mosquito Girl who decimated him and he was gonna blow himself up until a naked bald guy saved his mechanical ass who goes by the name of Saitama. From that day forward, Genos became the pupil/best friend of the One Punch Man himself.

Move Set:

-Incineration Cannon (焼却砲, Shōkyaku-hō): Genos launches a concentrated beam of fire to rapidly heat up a target to the point of being able to melt various metals. It was first used against Mosquito Girl.

>Maximum Gauge Incineration Cannon (最大出力焼却砲, Saidai Shutsuryoku Shōkyaku-hō): A variation of Incineration Cannon where Genos uses more energy than usual. It was first used against Saitama.

>Spiral Incineration Cannon (螺旋焼却砲, Rasen Shōkyaku-hō): An improved version of Genos's Incineration Cannon with the upgraded version of Genos's original incineration cannons received after the Super Fight Arc. It was first used against Phoenix Man but is blocked by Elder Centipede. The attack is strong enough to damage Senior Centipede's carapace.

>Super Spiral Incineration Cannon (超螺旋焼却砲, Chō Rasen Shōkyaku-hō): A variation of Spiral Incineration Cannon where Genos uses more energy than usual by firing the incinerating blast directly from the core. First used against Elder Centipede. The attack was capable of burning Elder Centipede's insides, making him molt, though it wasn't sufficient enough to permanently end Elder Centipede's life

-Self Destruct (自爆, Jibaku): If there is no chance of winning in combat, Genos can destroy himself and hopefully his opponent by overheating his core. He first attempted to use it during his fight against Mosquito Girl but stopped after Saitama interfered.

-Machine Gun Blow (マシンガンブロー, Mashingan Burō): Genos throws a chain of fast punches. It is strong enough to shatter a cliff face. It was first used against Carnage Kabuto.

-Dual Blade Rush (デュアルブレードラッシュ, Dyuaru Burēdo Rasshu): Genos jumps in the air, equips both arm blades, and rushes towards the target with his rocket boosters and proceeds to stab the opponent rapidly. It was first used against Elder Centipede when Genos tried to fight him alone.

-Boost Attack (ブーストアタツク, Būsuto Atakku): After using his left arm for jet propulsion in the opposite direction, Genos maneuvers towards his opponent and hits them with a strong kick from his left leg. It was first used against the Deep Sea King.

-Rocket Punch (ロケットパンチ, Roketto Panchi): Genos's forearm is retractable due to a cable connected to his elbow, which gives this attack great range. Genos punches his opponent with extreme force, amplified with boosters inside his lower arm. After the punch, his arm retracts back to its previous state. It was first used against G4.

-Lightning Eye (来航眼, Raikōgan): (Anime-only) Genos uses his eye to produce a blinding flash of light. It was first used against the Deep Sea King.

-High Voltage Fist (ハイボルテジフィスト, Hai Boruteji Fisuto): Genos chokes his opponent with a powerful, electricity-imbued hand and shocks them with it.

-Rocket Stomp (ロケットストンプ, Roketto Sutonpu): Genos leaps up above his opponent and then propels himself downwards with the rocket boosters on his back to stomp them into the ground.

-Lightning Core (雷光核, Raikō Kaku): Genos uses his core to produce a blinding flash of light. It was used during the second sparring match between Saitama and Genos.

-Jet Drive Arrow (ジェットドライブアロー, Jetto Doraibu Arō): Genos uses his rocket booster at full power to deliver a powerful kinetic kick while his leg releases sharp blades in the shape of an arrowhead. It is strong enough to break one of Elder Centipede's teeth.

-Thunder Drill Cannon (穿天雷光砲, Senten Raikō-hō): Genos charges up and unleashes a powerful energy beam. According to him, it is strong enough to blow up a meteor in one shot and deflect one of Fused Psykos' energy beams.

Feats(Strength and Durability):

-Held his own against Deep Sea King

-Destroyed a mountain of mosquitos and fought Mosquito Girl

-His upgrades allows him to now casually defeat Mosquito Girl and Deep Sea King

-Gotten uprated with G4 parts

-Equal to Speed-of-Sound Sonic

-Can tank his own incineration cannons

-Severely damaged Elder Centipede

-Destroyed a mountain

-His 10 second mode can allow him to one shot that meteor

-deflected blasts from a fused Psykos

-His True Spiral Incineration cannon can split apart Fused Pyskos' beam

Feats(Speed):

-Can Blitz the Deep Sea King and Mosquito Girl in a simulation

-Can keep up with Tatsumaki

-Equal to Speed of Sound Sonic

-Moved faster than Fubuki's perception

-Took on a weakened Psyrochi

-Intercepted attacks from Psyrochi in his 10 second mode

Stats(Strength and Durability):

-Genos vs. Mosquitos

>In his first battle against Mosquito Girl, he was able to destroy mountain of mosquitos in one shot which has been calculated to 62 tons to 10 kilotons which is City Block to Town Level

-Destroying a mountain

>According to Death Battle, Genos is able to destroy part of a mountain which has been calculated at 66 Kilotons which is Town Level

-Scaling to Deep Sea King

>The Deep Sea King is a Demon Level Threat which is a monster that threatens a city or multiple infastructures

>Which means he can go from 6.3 to 100 megatons at City Level

>This is consistent with Genos knocking around and or damaging Elder Centipede which is 16 megatons force which is City Level and since Genos can damage the inside of Elder Centipede and break one of his teeth, this can be scaled up to Mountain Level from scaling to Elder Centipede considering other Class S heroes like Atomic Samurai, Child Emperor, and as well as Metal Knight with prep time

-Scaling to Jet Psykos

>As Jet Psykos, she made a giant crater with a force of 403 kilotons which is Large Town Level

>And Genos scales to this

-Scaling to Speed of Sound Sonic

>Last time on Battle Match, I scaled  Sonic to be 70 gigatons at Island Level

-Ultimate upgrades

>His current upgrades allow him to now casually destroy the meteor which is 866 Gigatons which is Large Island Level

>Better than that, he can also match the power of Pysrochi's power which is 18 exatons, and he can scale to Orochi who can unleash 6 exatons to 5 zettatons which is Multi-Continent to Small Planet Level

Final Verdict: Multi-Continent to Small Planet Level

Stats(Speed):

-Mosquito Girl and Deep Sea King Scaling

>Mosquito Girl is much faster than her mosquitos, which has been calculated to be at speeds of Mach 4 to Mach 29 which is Supersonic to High Hypersonic

>This is consistent with dehydrated Deep Sea King being able to blitz Pri-pri Prisoner and moved fast enough to make rain drops stop in their place which is Mach 8 at Hypersonic

>And his later upgrades allow him to be faster than both of them in their strongest states

>Making him Massively Hypersonic by default

-Fubuki scaling

>In his fight with Song, Fubuki wasn't able to perceive their fight. and since it's been stated that no matter what Sonic and Genos are always equals which means he scales to Metal Bad who can dodge and block attacks from Garou at FTL speeds

-Current Genos attack speed

>Genos' beams have been calculated to be Mach 155 which is Massively Hypersonic which is consistent with the upscaling from the transformed Mosquito and Hydrated Deep Sea King

>Which is consistent with fused Psykos' attack speed which has been calculated to be around Mach 7278 to 3% of the Speed of Light at Sub-Relativistic

Final Verdict: FTL

Weaknesses:

-Has let his guard down multiple times

-Inexperienced in combat

-His gag is that he always lose just like how Saitama's gag is that he always wins

-Misunderstands Saitama's teachings

-Will resort to his self destruct when things get hopeless

Two of these monsters are ghosts called Napstablook and his cousin Hapstablook and Hapstablook was fascinated with humans and he became friends with Dr. Alphys. Soon Alphys and Hapstablook then became friends and soon watched anime and Dr. Alphys turned Hapstablook the Happy Ghost into a human manhunting fighting machine known as Mettaton. Dr. Alphys built Mettaton a robot body to impress the king of the Underground himself Asgore and after becoming the one only famous celebrity of the Underground he drifted away from Dr. Alphys with Mettaton focusing on his career while Dr. Alphys stuck on her work as the royal scientist.

-Heart to Heart: Mettaton EX's heart will fly out of his chest, firing bolts of lightning and electricity. Damaging or destroying the heart will also do damage to Mettaton himself.

-Disco Ball: Mettaton EX will summon a giant disco ball which fires lasers at his foes. Lasers of white light will always damage the opponent, but lasers of blue light are harmless to those who stand still. Hitting the disco ball will not damage it, but instead cause white lasers to turn blue and blue lasers to turn white.

-Chainsaw

-Rocket powered flight

-Forms:

>Box form: Focuses on defense

>Ex Form: Focuses on dancing skills and attack as well as electric attacks

>Neo form: has an attached arm cannon and a jet pack

Feats(Strength and Durability):

-His Box form allows him to be much more durable than Asgore or Undyne the Undying

-Is stronger than many other monsters in the underground in either of his forms

-Comparable to Undyne

-Made to be a "human hunting machine"

-Mettaton NEO is a lot stronger than you think

Feats(Speed):

Stats(Strength and Durability):

https://youtu.be/kDnxPy5KhPQ

-Transformation multipliers

>Mettaton's base alone can outmatch Undyne's undying form which is a 236x multiplier, so for every result from other monsters

>Base: 236x

>EX: 236x

>NEO: 236x

-Scaling to Humans

>Starting with the humans, since Mettaton is designed specifically to hunt down humans. That would mean he can tank hits no problem from them as well as deal just as much

>Which is 183 to 647 petatons of energy

>647 x 236 x 236 x 236 x 236 = 2 tenatons which is Dwarf Star Level

-Scaling to monsters

>A character named Knight Knight can use a Moon, Meteor shower, and a sun and it's solar flares and prominences

>With only the Meteor Shower which can produce up to 100 meteors, assuming each of these meteors have a kinetic energy of 100 teratons

>100 x 100 = 10 petatons which is Multi-Continent Level

>As for the Sun and Moon, a single prominence and solar flare can go from 100 gigatons to 10 petatons each. Which means Knight Knight can exert a force of 30 exatons to 164 tenatons which is Moon to Star Level

>164 x 236 x 236 x 236 x 236 = 21,197,303.5093 foe or 21.2 megafoe which is Solar System Level

Final Verdict: Solar System Level

Stats(Speed):

-Speed scaling

>Through out the game there were many instances where Frisk/Chara has dodged sound, electricity and lightning bolts and even light

>Which is Mach 5105 to 2.3x the speed of light which is Massively Hypersonic+ to FTL speeds

>This is consistent with the speed of solar flares and prominences at Mach .8 to Mach 5877 which is Subsonic to Massively Hypersonic+

Final Verdict: FTL

Weaknesses:

-Massive Ego

>Despite claiming he is going to finally finish the human, he fell for them saying there is a mirror behind him, instead of ignoring it and continuing to attack

-He is vulnerable to damage, unlike in his box form

-Overuse of his soul causes his limbs to fall off

>It isn't clear what exactly causes it, possible overuse of this form, the fact it is a work in progress, or some other means as to why it makes him fall apart

>He even falls apart if the player doesn't attack his heart

-When he makes his heart come out, it can be damaged

Battle

--------------------------------------------------------------------------------------------------------------

Here we see Mettaton signing autographs in City Z and there are groupies screaming Mettaton's name.

Groupies: "Mettaton! We're your biggest fans!"

Mettaton: "Well hello there ladies."

We then see Genos make a superhero landing on the ground and he walks past Mettaton and Mettaton then sees Genos.

Mettaton: "Well hello there."*takes a look at Genos*"My, my, you are so fabulous! The amazing face, those magnificent cybernetics, the stylish hair, and the street outfit is amazing."

Genos: "I don't focus on style, only combat capability and firepower."

Mettaton: "Well surely you need a stylist, with me as your stylist I can make you a star."

Genos then scans Mettaton and he sees that Mettaton is a monster.

Genos: "Another monster."*goes into a fighting stance*"I'll turn you into scrap."

Mettaton: "Ooooo, a fighter, you want to challenge moi? Well then, let the show begin."*to Napstablook*"Be sure you get my good side, Blooky."

Napstablook: "Isn't that every side?"

Mettaton: "Exactly Blooky."

We then see Genos fight off Mettaton and then we see him use his Machine Gun Blow on Mettaton but due to his durable exterior of his base form and we see Mettaton put up a finger up to Genos.

Mettaton: "Ah ah ah, this is not a proper stage of a show. I won't want my fans to be in the crossfire."

Genos: "Right, we will take this fight away from the city and into somewhere with much more room."

Frenchie: Later

We see Genos and Mettaton in a canyon and we see Mettaton's camera crew shooting the whole thing on the air.

Genos: "Now we begin."

Mettaton: "Right! Lights! Camera! ACTION!!!"

We then see Genos fire energy blasts from his hand as we see Mettaton use his Mini Mettatons to take the hits as well as fire projectiles at Genos as we see Genos get hit by the projectiles and then we see Genos charge in at Mettaton as we see Mettaton throw Cross Bombs at Genos and each of his limbs fall off and we see Mettaton pull out a chainsaw and then he cut off Genos' left arm as we see Genos launch his right hand at Mettaton and knock him back and we see Genos reattach his limbs and then his right hand.

Genos: "I don't fall apart that easily."

Genos then put his hands together and formed a powerful cannon and fired it at Mettaton and while Mettaton was in the shot he was applying sunscreen while wearing sunglasses. In the aftermath of the blast Genos was shocked to see that Mettaton is still intact and then he uses his Search Eye to scan for weaknesses as we see Genos blitz off and then sees a switch on Mettaton and then he flip it as we see Mettaton feels it happened.

Mettaton: "You.....flipped my......switch."

Mettaton then shakes and then he transforms into his EX form.

Mettaton: "Ooooh yessss."

We then see Mettaton now in his EX form and he sees Genos fire energy blasts at Mettaton and he uses his dance choreography skills to dodge the blasts until one of them hit him in the head and messes up his hair and made it into an afro and he checks his reflection in a pocket mirror.

Mettaton: "My hair.......MY.......HAIR!!!!!!!"

Mettaton then makes a disco ball appear and it shoots lasers at Genos as he dodges the blasts.

Mettaton: "That will keep him busy."*claps his hands*"Make up!"

We then see a make-up crew arrive and then redo Mettaton's hair and then Mettaton's hair is back to normal as we see Napstablook holding the latest ratings.

Napstablook: "Mettaton?"

Mettaton: "Yes Blooky?"

Napstablook: "The ratings came in and people are excited about your battle against The Demon Cyborg."

Mettaton: "Well then, let's give the audience what they want."

We then Mettaton turn to Genos and he sees Genos destroy his disco ball.

Mettaton: "That ball is worth 3 billion in gold!"*to Napstablook*"Send him the bill."

Mettaton then fight Genos up close with his dance moves and hit Genos with his fury of kicks except for the face and we see Mettaton knock Genos back with a powerful kick and we see Mettaton transform into his NEO form as we see Genos fly around releasing his adhesive gel to make sure Mettaton doesn't go anywhere.

Mettaton: "Ugh, most of this got into my hair! I just got it done!"

We then see Genos form his arms into a cannon and it was his Super Spiral Incineration cannon and he fires it at Mettaton and in the aftermath of the blast we see a blast of energy hit Genos and then he was down to the ground and he is unable to move his body and we see Mettaton pick him up in a Bridal Position and Genos sees this.

Genos: "If I'm going down, I'm taking you with me!"

We then see Genos use his self destruct to blow up Mettaton but it didn't work. We then see Genos wake up in a lab and he sees Dr. Alphys and Dr. Kuseno in the room along with Mettaton and other monsters of the Underground.

Papyrus: "He's waking up!"

Genos: "Where am I?"

Dr. Alphys: "Well Mettaton brought what's left of you here and Dr. Kuseno and I put you back together."

Undyne: "Going out with a bang against a TV Star robot, nice one!"*punches Genos' arm*"You got guts bud."

Sans: "Or nuts and bolts in this case."

Papyrus: "Sans!"

Genos: "Ugh, why did you save my life?"

Mettaton: "Your face and good looks can make any man or woman's heart throb. It would be a shame to let it go to waste."

Genos then fell a tug on his arm and he sees Frisk and Frisk looks at Genos with a smile on their face.

Genos: "I'm sorry, you wanted to make peace with humans. I was merely following my duties as a hero."

Undyne: "Eh, everyone makes the same mistake. Heck Asgore tried to kill Frisk and now he's like a dad to Frisk."

Asgore: "It is true."

Mettaton: "Tell you what, I'm hosting a talk show tonight and it will feature 3 heroes from the Heroes Association, this will be good for your image and to make up for everything between us."

Genos: "Of course."

We later see the MTT show and everyone is there and on stage is Genos, Saitama, Fubuki, and King and we see Mettaton asking questions.

Mettaton: "Now tell us, what is it like to be heroes based on your point of views?"

Saitama: "Why would you want to know that?"
