The Tanktop is the source of strength... If I can bring out even more potential of the Tanktop... If I become a man who is worthy of the Tanktop, then I can defeat even psychic power.
— Tanktop Master[1]

Tanktop Master (タンクトップマスター, Tankutoppu Masutā; Viz: Tank-top Master) is the S-Class Rank 16 professional hero of the Hero Association. He is the leader of the Tank Topper Army.


Tanktop Master is a very tall, muscular man with short, dark-blonde hair and brown eyes. He wears a blue tank top, long pants, and a belt around his waist with his initials and a tank top engraved on the buckle.[3]


Tanktop Master has a chivalrous nature, which can be seen when he noted that even if Tatsumaki is ranked 2nd, he should not let a "little girl" handle dangerous enemies on her own, despite the fact that Tatsumaki is actually an adult. He is also unafraid to admit defeat, for example, when he was outclassed by Tatsumaki during the encounter of Dark Matter Thieves aircraft. He is a very caring, wise man with honor and pride, and has a great affinity for his brothers and other heroes. This is in contrast to some of his Tanktop brothers, such as Tanktop Tiger and Tanktop Black Hole, who are shown to be very vainglorious and greedy. Additionally, he does not approve of his tanktops disrespectful behavior, and scolded them when they were rude towards Bang. Despite his willingness to admit defeat, he was still irked when Saitama said Tanktop Master "got his ass kicked the hardest".

Tanktop Master has an odd belief that true power comes from tanktops, as seen when he observes Bang dominating Metal Bat in their sparring match, he concludes that the secret to Bang's power is that he has a tank top hidden underneath.[4] However, this belief changes after being defeated by Garou.[5]

Abilities and Powers

Tanktop Master, as an S-Class hero, is one of the strongest heroes in the association as well as one of the physically strongest men on the planet. In his fight with Garou, who was able to defeat elite A-Class heroes with ease, he was able to not only harm Garou but hold the upper hand against the martial artist for the beginning and middle of the fight before being overpowered by his techniques. It was said by Garou that Tanktop Master's strength is around the level of Genos.

Physical Abilities


Tanktop Master's strength

Immense Strength: Tanktop Master possesses great physical ability. This can be seen when he hurls a large concrete block at both great distance and extreme velocity towards the Dark Matter Thieves' spacecraft. He was able to shake the ground with a punch, causing Garou to lose his balance momentarily. Unlike his fellow Tanktops, he was able to defeat one of Bofoi's drones with a suplex. He was able to send the monster Gyoffrey flying despite still recovering from his injuries in the fight with Garou. Tanktop Master claims that he has more "tanktop power" than all of the Tanktop army combined.[6]

Immense Speed: Tanktop Master was fast enough to catch Garou by surprise in their fight, able to hit him with a speed that shocked Garou. He also believes it would only take a month for him to clean up the debris from the alien attack. Although unseen, he was able to outrun the falling ship before it crashed on the ground.

Immense Durability: Tanktop Master has a high level of durability, requiring Garou to resort to using Water Stream Rock Smashing Fist. He was able to stay up after taking multiple hits from Garou, whereas his fellow tanktop army was defeated by single hits from Garou.

Enhanced Senses: While fighting Garou, Tanktop Master was able to sense evil intentions from Garou.

Fighting Style

Tanktop Tackle

Tanktop Tackle

Expert Hand-to-Hand Combatant: Tanktop Master apparently mastered the 'versatility' of the Tanktop, which he, according to his brothers, uses to increase the power of his attacks. His style of fighting consists of several punches and wrestling moves. However, as Garou evaluates, Tanktop Master mainly relies on power rather than technique.
  • Tanktop Blow (タンクトップブロー, Tankutoppu Burō): Tanktop Master spins to build up momentum and strikes the ground with tremendous force to unbalance and distract his opponent.[2]
  • Tanktop Tackle (タンクトップタックル, Tankutoppu Takkuru): Tanktop Master charges at his opponent, bulling them over with folded arms.[2] This attack is strong enough to blow a low-level monster a far distance away even when Tanktop Master is injured. According to the Tank Top Army, this move has defeated many monsters.
  • Tanktop Punch (タンクトップパンチ, Tankutoppu Panchi): A seemingly normal punch, although, according to the Tank Topper Army, his tanktop's "versatility" doubles its power.


Tanktop:  Tanktop Master wears a dull blue tanktop during training and battle, claiming it boosts his strength. It is unknown if this claim is actually true.

Warning The following section contains original webcomic spoilers. Expand to see spoiler content.

Attack Specialized Tight Tanktop: Tanktop Master wears this variant of the tanktop during his fight with Heavy Smoker. It boosts the wearer's strength due to the increased pressure on the body, but it can only be used for up to three minutes before it begins to suffocate the wearer.
