Tanktop Master (タンクトップマスター, Tankutoppu Masutā) is the S-Class Rank 15 hero. He is the eldest and most powerful of the Tanktop brothers, as well as the most level-headed and wise. He plays a minor role in the Alien Invasion arc, and a more major role in the Hero Hunt arc. Tanktop Master battles Garou to avenge Tanktop Vegetarian, and proves to be superior. However, upon seeing Garou's state, along with advice from Licenseless Rider, he decides to spare the human monster. Unfortunately, once Garou had seen through Tanktop Master's attacks, he went back on the offense and defeated the hero. In the hospital, Tanktop Master tells Saitama that Garou's fighting style makes him especially deadly to heroes.

Master 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, kicks and wrestling moves.
- Tanktop Blow (タンクトップブロー, Tankutoppu Burō): Tanktop Master unbalances and distracts his opponent by striking the ground with tremendous force after spinning to build up momentum.
- Tanktop Tackle (タンクトップタックル, Tankutoppu Takkuru): He charges at his opponent, bulling them over with folded forearms.
- Tanktop Punch (タンクトップパンチ, Tankutoppu Panchi): A seemingly normal punch, although, according to Tanktop Master's many brothers, his tanktop's "versatility" doubles its power.
