Tanktop Black Hole is a large, well-built man with short black hair. He wears a very simple costume of pants and a black tank top.
Tanktop Black Hole has a rather confident and stubborn personality. This is exhibited when he refuses to believe a C-Class hero could ever be capable of destroying a meteor. He is also a rather charismatic person, shown by his ability to bend a crowd to his will.
However, despite possessing a confrontational attitude and demeanor, he is also a coward deep down; best shown when he begged Saitama to spare him upon realizing he was out of his league while admitting to everyone he lied about Saitama being a villain.
After the destruction of the Meteor at the hands of Saitama, many people are left angry at Saitama due to the destruction of Z-City from the scattered meteor debris. Saitama is taking a walk around the ruins of Z-City when Tanktop Tiger jumps out and declares Saitama a liar and a cheater. Tanktop Tiger then calls out his brother. Tanktop Black Hole jumps out and begins to accost Saitama. Tanktop Tiger steps forward to attack Saitama, but Black Hole stops him, saying he has devised the cruelest way of punishing Saitama.
Black Hole takes a deep breath and starts yelling about how Saitama is the perpetrator of the destruction of Z-City, and how because of Saitama people are homeless and businesses have been destroyed. As he is yelling, inhabitants of the city start to be drawn towards the commotion and start going along with Black Holes's words. Black Hole uses this to his advantage and states that Saitama needs to quit being a hero, which further incites the citizens on his side, and causes them to dislike Saitama even more. At this point, using the negative atmosphere from the crowd to his advantage, Black Hole challenges Saitama to a duel.
Tanktop Tiger jumps forward to attack Saitama but is knocked away instantly. This enrages Black Hole, who then jumps forward and attempts to grab Saitama, but Saitama catches his hand and squeezes, causing Black Hole to give up. Black Hole then falls to his knees, saying that he gives up and that he's sorry for lying, and starts pleading for Saitama to let go. 
Tanktop Black Hole, along with the Tank Topper Army, find Garou to take revenge for him beating up Tank-top Vegetarian. After Tanktop Master engaged in a fight with Garou and lost, he assists his brothers and Mumen Rider in the fight against Garou, but they are all easily defeated.
Appearances in Other MediaEdit
Tanktop Tiger and Tanktop Black Hole are guarding a restricted area cordoned off by the Hero Association. He wonders why they're doing such a task when they're supposed to be heroes. He gets startled as Saitama shows up with a little girl, and both Tanktoppers demand to know what he's doing there, as only designated heroes selected by the officer in charge are allowed into the isolated zone that they're guarding. To his surprise, Saitama nonchalantly states that he's one of them. Despite the circumstances, he and Black Hole allow him to go in, knowing the consequences if they try to stop him.
After the Dark Matter Thieves invasion, the Tank Toppers were alerted about the arrival of a large machine descending upon the Headquarters. Tanktop Black Hole and the other Tank Toppers arrive to stop the drones sent out by the machine but are largely unable to prevent its intervention. Only after realizing that the machine was controlled by Metal Knight to reconstruct A-City into the Hero Association's new headquarters did he and the other Tank Toppers step down.
Tanktop Black Hole makes a cameo appearance when talking about the Tank-Toppers.

Enhanced Strength: Black Hole is a rather strong individual, boasting a grip strength of 200 kilos.
Hand-to-Hand Combatant: Like the rest of the Tank Topper Army, Tanktop Black Hole seemingly prefers unarmed close-quarters combat. He mostly makes use of his great grip strength.
