Jupiter is a passive item added in The Binding of Isaac: Repentance.
Effects[ | ]
- Grants two Red Heart containers, of which half a heart will be filled.
- -0.3 Speed.
- Standing still causes Isaac to build up speed at a rate of +0.25 per second, up to a +0.5 speed bonus.
- Isaac charges up while standing still. Moving releases a fart cloud behind Isaac, damaging and inflicting Poison on enemies that pass through it and draining the speed buff at a rate of -0.25 speed per second. The fart clouds are left behind for the duration of the speed buff.
- The fart clouds deal 0.5x Isaac's damage per tick (1.5x Isaac's damage per second), and last ~2.5 seconds.
- Isaac is immune to Poison from enemies, such as
Gasbag or Mushrooms.
Notes[ | ]
- As the speed buff requires Isaac to stand still, Jupiter is effectively a speed down.
- The fart clouds are mechanically independent of the speed increase. Even while at max speed, the fart cloud must be charged by standing still.
- Jupiter acts solely as a flat +0.20 speed boost and +2 soul hearts for Tainted Forgotten with no other effects.
Synergies[ | ]
- Camo Undies: Damaging enemies with the fart clouds will not take away Isaac's camouflage.
- Dark Arts: Stays in effect even while using Dark Arts, allowing Isaac to deal more damage to nearby enemies while invulnerable.
- Gigante Bean: Greatly increases size of fart clouds.

Trivia[ | ]
- Jupiter, as well as Neptunus, was designed for the original Antibirth mod, but never actually implemented until Repentance.
- Jupiter's effects and pickup quote reference the planet Jupiter's nature as a gas giant, being composed mainly of hydrogen and helium in gas and liquid form.
- The item's ability to create fart clouds after standing still and poison immunity could be a reference to Nuclear Throne, where the character Frog has similar abilities.
