Tomb of the Boom is a fairly small Stand with a vaguely humanoid upper body. Each version of the Stand bears a largely different appearance from each other; In all three versions, it possesses an elongated face with a long tongue coming out of a small mouth, resembling that of a giant anteater.
On Tomb of the Boom 2 and 3, the top half of the Stand's head is open, revealing an eye-shaped object inside it. Tomb of the Boom 1 instead has hood-like metallic bars over its head.
The shape of the lips of each Tomb of the Boom also differ: TotB 1 has thick, puckered lips; Tomb of the Boom 2 is the most anteater-like, with a perpetual smile on its face; TotB 3 has circular, multi-layered lips.
All versions of Tomb of the Boom possess long, sharp fingers, with TotB 3 having four on each hand rather than five. Tomb of the Boom 2's hands are striped.
Tomb of the Boom 2's lower body is a mass of human legs, with some disproportionately small, arranged in such a way that they resemble the legs of a crab; the amalgamation of many body parts may allude to the fact that it has several users, though the full bodies of the other two are never shown.
Tomb of the Boom is dark purple in the colored manga.
Once turned, every metal object near the victims will be attracted to them and will sink into their body, causing crippling wounds. André can magnetize several people at once and the victims will also attract each other. If the affected people get far enough from the Boom Boom Family, the magnetism weakens, but if they sufficiently approach a victim, the magnetism is so powerful that the victims' bodies will rip themselves apart. The magnetism also becomes more lethal depending on the number of affected people in close proximity of each other.
