Overview
Flashy Flash (閃光のフラッシュ, Senkō no Furasshu) is the S-Class Rank 13 professional hero of the Hero Association. He is a former member of the Ninja Village's 44th Graduation Class, nicknamed "The End."
He is also one of the few people aware of Saitama's power.
Appearance
Flashy Flash is a lean but muscular young man of average height with an androgynous appearance. He has sharp blue eyes and long ice-blonde hair with bangs brushed to the right side of his face.[2] He wears a dark blue bodysuit with metallic bracers over his arms and upper chest armor with a long white cape over it. He adorns himself with two eight-pointed stars on either side of his head and on his cape. He has a chain strapped around his waist that holds his sheath and sword in place.
Personality
Flashy Flash is a calm and serious man, immediately starting the topic of discussion at the meeting and stopping an argument between Tatsumaki and Metal Bat. He also appears to be quite arrogant, telling lower-ranked heroes to step aside and let him handle the Mysterious Being because he sees them as weak, berating them for potentially causing collateral damage. He is also very confident in his abilities.
Flashy Flash is one of the few heroes who doesn't fear Tatsumaki, talking back to her after she insulted him, stating that she stole his kill against the Hundred-Eyes Octopus, and even went as far as to say that she is not actually stronger than him.
He has a very firm mindset that training is one of the only ways to become truly strong, as he told Gale Wind and Hellfire Flame he only became as powerful as he was through training more than any other heroes or ninja. When the two monsters were dying, they asked Flashy Flash what it was that they were missing, and his response was their lack of training. In a sense, this is similar to Saitama, as he also believes training is the only way to become truly strong.
Despite his collected composure, Flashy Flash has a tendency to be hasty and reckless. His careless attack on Hundred-Eyes Octopus only made the beast cause more destruction, and he has other lapses in judgment such as losing his communicator during the Monster Association raid or attacking Saitama even after recognizing him as a hero.
While normally prideful and rude, he did compliment Saitama after witnessing his strength and speed. When he attacked Saitama under the suspicion of being a monster, he was stunned when Saitama avoided his first attack. Though he remembered who Saitama was, he wanted to confirm if he could actually dodge his attacks as his pride wouldn't allow such a thing, making him attack Saitama again, which was actually an unnecessary endangerment of his life.
However, he is incredibly respectful of those he deems strong and is more than willing to give praise to such individuals. An instance of this is when he and Saitama work together with a monster to find the Monster Association's inner sanctum. In a gold mine, he defends against a series of larger monsters' attacks. Unbeknownst to him, Saitama does so as well and keeps an equal pace to him. He is astounded and impressed by Saitama's strength, calling him "Pretty good."
Abilities & Powers
As an S-Class hero, Flashy Flash is very powerful. In terms of speed, Flashy Flash is arguably the fastest S-Class hero in the association, though he seems to be outmatched against the top-ranked S-Class hero Blast. He is the former top ninja of the 44th graduating class of the village that Speed-o'-Sound Sonic hails from. Flashy Flash is also one of the few S-Class heroes capable of defeating multiple Dragon-level monsters singlehandedly, as he was able to kill Hellfire Flame and Gale Wind, two powerful Dragon-level threats known for their remarkable speed without sustaining any significant damage or visible fatigue, although he needed to use his finishing move to eliminate them. According to Darkshine, if Garou were to fight him, he would most likely die before being able to show any of his techniques.
Flashy Flash is also a very analytical fighter. He strategically waited for the right moment to incapacitate Gale Wind and Hellfire Flame simultaneously to prevent either from escaping, reasoning that the other heroes would have trouble with the ninjas' speed. He was also able to discern Saitama's physical attributes by analyzing the sound of his footsteps.
Physical Abilities
Immense Speed and Reflexes: Flashy Flash possesses incredible speed and reflexes, surpassing most characters in the series. His speed leaves powerful shock waves in his wake. He was able to travel to Hundred-Eyes Octopus, a Demon-level Mysterious Being, and slash the monster's eyes in the blink of an eye using his incredible speed. During the initial attack against the Monster Association, Flashy Flash dispatched some monsters so quickly that Shadow Ring, a fellow ninja, could not see what happened. He was able to easily keep up with two Demon-level monsters known for having remarkable speed, Hellfire Flame and Gale Wind in their human forms, only taking some pressure when they transformed into their Dragon-level monster forms and was able to kick them at speeds they were unable to counter. After having stunned Gale Wind and Hellfire Flame with a barrage of fast kicks, he managed to cross a great distance and perform one of his ultimate techniques, Flashy Slash, slicing the two Dragon-level monsters in half before they could even react, and his actions were so fast that they seem to happen almost at the same time. Flashy Flash's speed was also remarkable enough to impress Saitama, with the bald hero stating he was "kinda fast".
Immense Strength: Flashy was shown to be strong enough to combat and kill two Dragon-level threats simultaneously. He can deliver powerful kicks that can stun Dragon-level monsters. He can also easily cut massive pieces of stone and create giant explosions throughout his fighting. Additionally, the large crevice where he was battling Gale Wind and Hellfire Flame was completely destroyed as a result.
Immense Durability: Flashy Flash is shown to be quite resilient. He was able to sustain numerous direct hits from two powerful Dragon-level monsters Gale Wind and Hellfire Flame at once without any serious damage, only coughing up small traces of blood.
Enhanced Senses: Flashy Flash was capable of estimating that Saitama’s weight was around 70 kg based on his footsteps, and also realized that his presence didn’t match that of any member gathered there.
Fighting Style
Ninjutsu Master: Gale Wind noted that Flashy Flash's technical precision surpassed both his and Hellfire's. Flashy Flash also states that he has trained more than any other ninja from The Village.
Wind Blade Kick (風刃脚, Fūjin Kyaku): Flash throws himself at his foe and does a front flip, during which he throws his foot out to kick his opponent, using the momentum of the flip.
Heavy Flashy Slash (重閃斬, Jūsenzan): Flashy Flash thrusts his sword forward multiple times to pierce through his target. This technique was used to break Hellfire Flame's sword.
Flashy Kicks (閃光脚, Senkō Kyaku): Flashy Flash delivers a kick numerous times at incredible speed. They contain enough power to stun two Dragon-level monsters.
Maximum Speed Flashy Kicks: Flashy Flash delivers multiple kicks at his fastest speed. Flashy Flash first uses this to test Blast's abilities, but the hero is easily able to dodge the attack.
Ultimate Techniques (絶技, Zetsugi): Flashy Flash's set of ninjutsu techniques unique to him.
Flashy Slash (閃光斬, Senkōzan): Flashy Flash's ultimate technique. The technique allows Flashy Flash to move at unimaginable speeds toward his opponents, slashing them before they have any time to react, even against superb ninjas like Hellfire Flame and Gale Wind. Furthermore, this technique can be used to cut his opponents in half or decapitate them. Before Saitama, no one had ever been able to dodge it.
Equipment
Katana: Flashy Flash wields a katana with a round guard called Instakill (瞬殺丸, Shunsatsumaru, Viz: Flashkill). He is very skilled in using it in combat, as he defeated two Dragon-level monsters with it. The sword was broken when Flashy Flash was trapped under a cave-in and its blade got stuck in the rock, which Tatsumaki ripped out of the ground.
