— Metal Bat

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

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 gakuran, which he drapes over his red long-sleeved turtleneck sweater.


Metal Bat has a great deal of confidence in himself, stating that he did not care whether a threat is a Demon or Dragon level.[3] 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. He speaks in a very rough dialect, pronouncing "yer" instead of "your."

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 promise to never show her violence.[4] He has also shown 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 killed Rafflesidon and Senior Centipede before he could get any answers for their motivations.

Abilities and Powers

As an S-Class hero, Metal Bat is very powerful. Despite his low rank, he is a powerful combatant, threatening Sweet Mask whose strength is 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 in the midst of 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 on against Garou in a duel despite being gravely injured earlier by repeated battles against increasingly powerful enemies.

Physical Abilities

Metal Bat Power

Metal Bat's incredible strength

"When the intensity of Metal Bat's anger reaches its maximum, his power approaches infinity."[2]:

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, including Senior Centipede, whose carapace can withstand Genos' Incinerate without being damaged.[5][6] Even without fighting spirit, he has shown to be able to kill demon-level foes with one swing.[7] While being unable to kill the Elder Centipede with one hit, he did push it down and completely stop it in its tracks. It's noted that his fighting spirit heightens his strength, as Garou observed that the more 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 shock-waves. Garou even complimented him, stating that if he received even a single strike from the bat, he would have lost the fight.[8]

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, an extremely powerful fighter capable of easily defeating super-human foes.[9] In addition, 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 afterwards.[10] 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.[11] 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.[12][13][14] Virtual Genocide System's (VGS) simulations show that Metal Bat without fighting spirit can fight Carnage Kabuto in Carnage Mode for three minutes.[15]

Scaled Endurance: Metal Bat possesses a great deal of endurance. Metal Bat can seemly 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.[16] Metal Bat was able to fight and survive through battles with multiple tiger-level and 2 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.[17]

Immense Stamina: In the anime, Metal Bat possesses a high level of stamina without the need to activate his fighting spirits, as he was shown to continue fighting Melzalgald, showing no signs of fatigue. Furthermore, Metal Bat's stamina, with his fighting spirit, can grow endlessly as he continued to fight numerous enemies over a long period of time without the need to rest.[18]

Immense Speed and Reflexes: Metal Bat was able to escape a falling spaceship fairly easily, and he even considered Puri-puri Prisoner slow.[19] Metal Bat also possesses superhuman reflexes as seen in his fight against Garou, where he's able to deflect and block Garou multiple punches despite being injured in his battle against Elder Centipede. Metal Bat's speed, with fighting spirit, can even grow to be too fast for Garou's martial arts to compensate.[20]

Psychic Resistance: Metal Bat's indomitable will granted him the ability to be immune to certain psychic forces and very resistant to others, due to his astonishing willpower known as the Fighting Spirit.[21]

Increased Healing Factor: Metal Bat possesses the ability to recover from minor blood loss and fractured bones in a matter of days just by resting.[22]

Fighting Style

  • Metal Bat using Dragon Thrashing on Elder Centipede.
  • Garou facing Metal Bat's Savage Tornado.

Killin' Moves (Viz: Killer Moves): Metal Bat usually fights by bashing his opponents into submission or death with his bat like a 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.

  • 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.[23] 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 if the bat had hit him once, it would have been the end for him.[24]

Miscellaneous Abilities

Fighting Spirit (気合い, Kiai): Metal Bat is capable of getting stronger through his damage intake and anger build up.[25][2] 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 both more durable and stronger as the fight went on.[26] However, his Fighting Spirit lowers extremely fast when he is out of battle and exhaustion can quickly set in.

  • 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.[27]

Keen Perception: Despite his brash nature, Metal Bat seems to be very perceptive, as he was the first one to discover Melzalgald's weakness. In addition, he was able to notice that Elder Centipede avoided getting his head in contact with Metal Bat's attack and thus deduced that its unprotected face is its weak spot.[28]


Metal Bat: Living up to his name, Metal Bat carries a gray metal bat, which has a black handle. Metal Bat uses his metal bat to take care of monsters. It is, with Metal Bat's strength, strong enough to kill demon class monsters with one hit. It was made personally when he joined S-Class, and he requested that it wouldn't break.[29]
