Dormant form

The Stand featured in this article is commonly referred to as "Ozone Baby".

Ozon Baby (オゾン・ベイビー Ozon Beibī) is the Stand of Poor Tom, featured in JoJolion.


Before activation, Ozon Baby appears as a near-exact replica of the LEGO Architecture White House 21006. This form has no unusual qualities to it.

Post-activation, Ozon Baby appears as a mechanical Stand with a half-humanoid form. Instead of legs, it possesses a set of wheels for movement, but can freely float and move.

The top half of its head is covered by a bag-like helmet, covered in spikes and having the Stand's name imprinted on it, and black, sunken eyes. The bottom half of its head appears as a muscular humanoid head, several square-like imprints around its mouth, and black lips stretched into a grin. Its arms extend from curtain-like shoulders, beginning as bone-like structures and becoming more flesh-like at the elbow, though its forearms are covered in cloth-like material. Its fingernails are long and black, looking more like claws.


According to Jobin Higashikata's findings, Ozon Baby is a long-range automatic Stand, thus possessing a powerful ability sustainable even away from its user Poor Tom. However, proximity to Tom himself dramatically increases the pressure variations. Tom reveals that its power has an area of effect of 100 meter radius.

Ozon Baby's power revolves around manipulating air pressure in a way capable of cordoning off an area. Burying the Lego house in the soil dampens the effect of the pressure.

Pressure manipulation

Upon activation, Ozon Baby automatically begins to cause the surrounding atmosphere to depressurize. Hollow objects such as plastic containers begin to collapse in on themselves, and living organisms begin to experience mild depressurization sickness, with symptoms such as pain in the ears and nosebleeds.

If one steps outside of a sealed room, the depressurization sickness becomes dramatically more severe. All the air dissolved inside the blood vessel form bubbles, causing severe bleeding in the capillaries, notably in the eyes, nose and ears, which can debilitate a grown man in seconds, and cause eyes to pop out of their sockets. This effect is likely to prove lethal if the exposure is prolonged.

Any room that is opened but then closed regains its atmospheric pressure, the walls and closed openings acting as barriers to Ozon Baby's power. Any surviving victim managing to regain the safety of a closed room can recover from their depressurization sickness. However, merely staying inside a closed space is also dangerous as the pressure inside will gradually increase to lethal levels. At its worst, the crushing pressure causes the body to cave in on itself.

In addition to this area-of-effect depressurization, Ozon Baby can create illusions of itself.
