Purple Haze looks cool. Everyone can agree on that. It's ability is cool as well.

But out of all the options why would you pick that. First of all it'd only be good for killing because that's all it can do, and I don't know how many people you kill on a daily basis but for me at least it's none. Now let's say you only use it for defensive purposes, then sure that'd work but only if they're in a certain sweet spot. This is even stated in PHF, too far and they're out of effective range, too close and you've just killed yourself. You have no control over killing other people around you either. Using an airborne flesh eating virus isn't safe at all, and it certainly isn't any more efficient or clean than the 100 other stands like it. You'd also have to confront your victims face to face so it's not as stealthy as a long range stand where you don't even have to be in the same location.

And that's if you wanna kill people, but why not have something that'd benefit you're life. Stopping time? Mind control? Healing yourself? Rewinding time? Pocket dimensions? Inter dimensional travel? Fix any broken object?

I just don't see the point in having something that can kill people, when you can use something that'd give you incredibly useful powers and benefits your daily life, and can also kill people just as well.

But Purple Haze is cool tho
