Heavy Weather

Heavy Weather is either a sub-stand or the unleashed form of Weather Report. In this form the stand has not a physical form and the user can't control its powers completely. Its name is based on the album of the same name by Weather Report.

Abilities
Snail Projection: In addition to the existing abilities of Weather Report, Heavy Weather can subconsciously alter the atmosphere and hence the projection of light, creating various rainbows to fill a vicinity. If someone were to gaze at the projected light, their bodies would morph into snails due to subliminal messages, rendering them practically immobile and weak to salt and natural predators. One can also begin to turn into a snail by physically touching one of the snails created, or an individual already turning into a snail. Due to the large number of snails and their tendency to move toward other living creatures, this ability is very dangerous and nearly unavoidable.

Self-Defense: Weather Report can also electrocute anyone who comes in contact with his body.

Oxygen Build-Up: Lastly, Heavy Weather can fill a room completely full with oxygen, paralyzing an opponent indefinitely or intoxicating them with the lethal level of pure oxygen.

Trivia

 * Heavy Weather is the only Stand used by two people on separate occasions: Weather Report and Emporio Alnino, as well as the only stand stated to have entirely unknown stats (several Stands in Part III did not have released stats and Anubis was used by more than two people while searching out a user).
