Bad

Fuck reasons. It's fightin' spirit.

Bad (バッド, Baddo), better known by his hero alias Metal Bat (金属バット, Kinzoku Batto), is the S-Class Rank 15 professional hero of the Hero Association.

After the battle against the Monster Association, Metal Bat quits the Hero Association and joins the Neo Heroes. His reason for leaving is still unknown.

Appearance
Metal Bat is a young man with black hair styled in a pompadour, and dark eyes that emphasize his hot temper. He wears black bontan pants and a black Japanese school uniform, which he drapes over his red long-sleeved turtleneck sweater.

Personality
Metal Bat has a great deal of confidence in himself, stating that he does not care whether a threat is a Demon or Dragon level. He also seems to be brash and reckless, as shown when he immediately smashed one of Melzargard's marbles instead of trying to analyze what purpose it serves for the enemy. Furthermore, he was willing to challenge Sweet Mask for his mocking attitude before being interrupted by a call from his sister and Sweet Mask's manager.

Despite his brash attitude, he still has a soft side in him when it comes to his sister, Zenko, who he treats very well and spoils to an extent. He values promises between Zenko as shown where he refused to take down Garou in Zenko's presence despite being attacked by him due to a commitment to never show her violence. He has also demonstrated similar love towards his pet cat, Tama. Like Saitama, he doesn't care about his rank, and accidentally kills his enemies faster than he intended, such as when he executed Rafflesidon and Senior Centipede before he could get any answers for their motives. After waking up he is usually quiet unlike usual, though he claims he is not a "morning person."

Abilities and Powers
As an S-Class hero, Metal Bat is very powerful. Despite his lower rank, he is a powerful and intimidating combatant, threatening Sweet Mask (whose abilities are worthy of S-Class) with no fear, as well as holding his own against Garou.

He is particularly hardy, capable of taking on multiple Demon-level monsters at once even after being drugged by one amid the fight. He has also stood up to dragon-class monsters, managing to cause Elder Centipede considerable pain with his swings. He was also able to fight against Garou in a duel, despite being gravely injured earlier by repeated battles against increasingly powerful enemies.

Physical Abilities
"When the intensity of Metal Bat's anger reaches its maximum, his power approaches infinity.":

Evergrowing Strength: Metal Bat possesses immense physical strength and has taken out many powerful monsters and villains with a single swing of his bat, including two Demon-level monsters simultaneously, even Senior Centipede, whose carapace can withstand Genos's Incineration Cannon, could not survive a single swing from his bat. Even without fighting spirit, he has shown to be able to kill Demon-level foes with one swing. Despite being unable to break Elder Centipede's incredibly tough carapace, he did push the giant monster down and completely stopped it in its tracks. It's noted that his fighting spirit heightens his strength, as Garou observed that the longer the fight drags on, the more powerful Metal Bat becomes, to the point that he can easily destroy buildings and tear the ground apart, causing powerful shockwaves. Garou even complimented him, stating that if he received even a single strike from the bat, he would have lost the fight. The power of his swing has impressed the likes of Superalloy Darkshine and Bang.

Immense Speed and Reflexes: Metal Bat was able to escape a falling spaceship fairly quickly, and he even considered Puri-Puri Prisoner slow. Metal Bat also possesses superhuman reflexes as seen in his fight against Garou, where he's able to deflect and block Garou's multiple punches despite being injured in his battle against Elder Centipede. Metal Bat's speed, with the fighting spirit, can even grow to be too fast for Garou's martial arts to compensate. However, Murata has stated that Metal Bat is slower than Sonic.

Immense Durability: Metal Bat also possesses immense durability. He was able to take many hits from Senior Centipede, a Demon-level monster with piercing power, and from Garou, a mighty fighter capable of easily defeating superhuman foes. Also, he received a direct hit from Elder Centipede that sent him crashing into a building which destroyed part of it upon impact but did not seem to be fazed by the attack afterward. His durability also becomes more powerful with more fighting spirit; as the fight between him and Garou progressed, he became almost immune to some of Garou's attacks. Additionally, Metal Bat was capable of withstanding his own attacks that contained twice the original power redirected by Garou, along with showing little reaction to hitting himself on the forehead with his bat in order to counter Rafflesidon's tranquilizing gas. Virtual Genocide System's (VGS) simulations show that Metal Bat can fight Carnage Kabuto for three minutes.

Scaled Endurance: Metal Bat possesses a great deal of endurance. Metal Bat can seemingly continue fighting for as long as he has Fighting Spirit, as he was able to go beyond his body's limits. He can continue fighting even when he has immense amounts of bleeding and multiple fractured bones. Metal Bat was able to fight and survive through battles with multiple Tiger-level and two Demon-level mysterious beings along with 1 Dragon-level mysterious being and Garou in rapid succession with little time in between them to rest. Metal Bat states that if he had fighting spirit during the Virtual Genocide System's (VGS) simulation, he would have performed better against Carnage Kabuto.

Healing Factor: Metal Bat possesses the ability to recover from minor blood loss and fractured bones in a matter of days just by resting.

Fighting Style
Killin' Moves (Viz: Killer Moves): Metal Bat usually fights by bashing his opponents into submission or death with his bat, not unlike a typical delinquent. However, if there are opponents who can either withstand them or evade them, he swings his bat at different intervals and in unorthodox ways to be able to strike them down. Among his array of moves, he also has ones made and used to finish off his opponents. Garou judged Metal Bat's overall fighting style to be like that of an amateur's.
 * Dragon Thrashing (怒羅厳シバき, Do Ra Gon Shibaki, Viz: Dragon Pummelin'): Metal Bat unleashes a barrage of smacks with his bat at the same spot in multiple angles. This attack was first seen used against Elder Centipede. The attack was powerful enough to cause Elder Centipede to shout in pain.
 * Savage Tornado (野蛮トルネード, Yaban Torunēdo, Viz: Brutal Tornado): Metal Bat wildly spins with his trademark weapon strong enough to create a small tornado. The attack is powerful enough to cause slight damage to Garou even when the latter was repelling the strikes. In their battle, Garou commented that had the bat managed to hit him even a single time, it would have been the end for him.

Miscellaneous Abilities
Fighting Spirit (気合い, Kiai): Metal Bat is capable of getting stronger through his damage intake and anger buildup. This is because of his will to continue to fight regardless of what happens. Instead of succumbing to the damage he receives, Metal Bat gets an increase in his physical attributes. This ability is mainly shown during his fight with Garou wherein he got became more durable and stronger as the fight went on. However, his Fighting Spirit lowers extremely fast when he is out of battle and exhaustion can quickly set in. Keen Perception: Despite his brash nature, Metal Bat seems to be very alert, as he was the first one to discover Melzargard's weakness. He was able to notice that Elder Centipede protected his face and deduced that its unprotected face was its weak spot. Metal Bat was born with amazing dynamic vision.
 * Mental Resistance: Metal Bat, due to his indomitable will, cannot be completely controlled by mind control abilities. He was able to somewhat resist Rafflesidon's gases, and by hitting himself with his bat, Metal Bat was able to entirely escape the influences of Rafflesidon's gases.
 * Psychic Resistance: Although never seen resisting psychic power before. Metal Bat seemingly has the ability to withstand certain psychic forces, allowing him to resist psychic powers due to his astonishing willpower known as the Fighting Spirit. This was shown when Garou managed to adapt to and move his body while being affected by Gyoro Gyoro's psychic powers while Garou himself also referred to it as the Fighting Spirit.

Equipment
Metal Bat: Metal Bat's signature weapon. It is a gray metal bat with a black handle. It is, with Metal Bat's strength, strong enough to kill Demon-level monsters with one hit. It was crafted personally for him when he joined the ranks of the S-Class and requested a bat that wouldn't break.

Neo Heroes Battle Suit: After joining the Neo Heroes, Metal Bat wears a Neo Heroes Battle Suit, which provides him with a variety of functions. Upgraded Bat: Metal Bat's new weapon. In addition to providing all the functions of his old bat, the upgraded bat has retractable spikes and can generate electricity, both of which substantially increase power output.
 * Mobility Analysis: The suit analyzes Metal Bat's nervous system and body, with its synthetic muscle reacting accordingly and enhancing his physical abilities.
 * Life Support System: The suit contains a life support system, although it can be damaged beyond function.
