The Tank Topper Army (タンクトッパー軍団, Tankutoppā-gundan) is a group comprised of the Tank Toppers, under the leadership of Tanktop Master.


Every member of the Tank Topper Army wears a tank top. The designs of each member's tank top vary.


Every member of the Tank Topper Army takes great pride in their tank tops and associates them with a symbol of strength and pride. Many of the members are shown to be extremely rude and arrogant towards everyone but their leader, although Tanktop Master does not approve of this behavior.[1] All of the members of this army worship the words of Tanktop Master, and believe that the path to true strength is through tanktops: ironically, Tanktop Master believes this more than anyone, 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.[2]

  • A running gag for the Tank Top Army is that they are always beaten or humiliated.
    • Tank Top Tiger gets hit by Sonic's Exploding Shuriken.

    • Tank Top Master felt weak when Tatsumaki was able to pick up thousands of rubble pieces right after Tank Top Master threw one himself. He felt the same way again after Metal Knight came back to rebuild A-City.
    • Tank Top Vegetarian got pummeled by Garou, and then punched in the face again by Garou.
    • Tanktop Master was defeated and hospitalized after Garou adapted to his movements and began using his Water Streaming Rock Smashing Fist.
