Bruce Banner and his stand [Rage Against the Machine]/[Hulk]
Hulk is an absolute brute of a stand, often smashing first and leaving Bruce unable to ask questions later. His power and durability know no limit, the angrier he gets, the stronger and more durable he becomes but at a price.
When called upon Hulk releases gas from his body which spills from his eyes, mouth, chest, shoulders and knuckles. The angrier he gets, the wider the holes become for the gas to spill out and the further it can travel. The gas sends anyone within its vicinity into a blind rage, including Bruce himself; that's why he doesn't like to use Hulk unless it's absolutely necessary.
Hulk has a range of 5 metres and the gas affects things within 1 metre of Hulk when he's calm, but can build all the way up to an 8-metre radius, meaning Bruce needs to keep a close eye on his stand and pick and choose his moments, lest he succumb to the gas and rampage with his stand until they both run out steam.
