The Storm Cloud is an Item Box power-up that appears in the Sonic the Hedgehog series. It is a Trap Item used primarily to obstruct opposing rivals' path.
Description
The Storm Cloud's icon take the form of a blackish thundercloud that emits a light blue lightning bolt. In gameplay, this power-up becomes a row of floating gray thunderclouds that constantly emit purple lightning.
Once obtained, the player can utilize the Storm Cloud by pressing its icon on the bottom of the HUD. When used, the user drops this power-up's thunderclouds some distance ahead of the user's current location on all the lanes that the user is not currently on. If a character, including the user themselves, touches one of these thunderclouds or their lightning bolts, they will be stunned, thus causing them to lose Rings and stop moving for a moment, and lose one random power-up in their inventory slots on the HUD. To avoid the Storm Cloud, the playable character must either slide underneath its storm clouds or run in-between them.
The Storm Cloud can also be upgraded by leveling the user up to level 4, 10 and 16 respectively. For each upgrade, the zap effect of the Storm Cloud will be extended.
