Heavy Weather

Heavy Weather (ヘビー・ウェザー Hebī Wezā) is either a sub-Stand or the unleashed form of the Stand Weather Report, both belonging to the character Weather Report; featured in Part VI: Stone Ocean.

This Stand has no physical form, and its user cannot control its powers completely.

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.

However, this ability is not without a weakness. As discovered by Enrico Pucci, a blind person is immune to the effect of the stand, since they can't see the subliminal messages carried through sun rays. This allowed Pucci to be effectively immune to the effects of Heavy Weather, by having his stand Whitesnake extract his ability to see, blinding him in the process. Still, once a person starts transforming into a snail, the process is irreversible.

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

Trivia

 * Weather Report is named after the Jazz Fusion group Weather Report, just like Heavy Weather comes from one of their most popular albums.
