Yes, it's Buzzkill: a superhero to some, a super villain to others! Buzzkill "trips" across the land, killing people who are getting high, the deadliest assassin in the War on Drugs!
How came he to be this way, this deadly vice warrior, killing buzzes and those who have them? Well, his origin is believed to be as follows:
He was a fierce DEA agent, always wanting to bust drug dealers and druggies alike, when on one occasion, while trying to bust a gang of drug kingpins making batches of LSD, crystal meth, PCP, cocaine, heroin, ecstasy, GHB, Special K, and all that other stuff, next to a nuclear power plant, a shootout between the DEA and the drug dealers caused a radiation leak, and then a flash-bang grenade set off a small nuclear explosion just as he was kicking in the front door, soaking him in a radioactive lysergic acid drug bath, granting him extra-sensory perception to detect and locate people getting high (!). And once he hones in on these druggies, he lets loose with his Super Drug Ray, instantly overdosing them in whatever drug they're currently high on (!!). Of course this put him on the wrong side of the law, distributing drugs in such a way, plus killing people, but big supporters of the drug war think he's a hero (especially the ones who hate the idea of letting people get high).
So he's a hero and a villain, depending on who you ask, with undeniable super powers. And if you're secretly getting high somewhere, beware you don't find yourself in the sites of Buzzkill, the ultimate buzzkill of all! (Just another thing to be paranoid about, man...)
Oh, but might Buzzkill reverse his sympathies, changing sides in the War on Drugs to instead of killing buzzes and those who have them, getting everyone high instead? Perhaps he'll have a change of heart and get everyone in the DEA high so they can mellow out for a change! Oh, but if he's going to do that, he'll have to transform from Buzzkill to The Stoner.
And if he becomes The Stoner, he'll have to team up with his new sidekick superhero Munchie Man to deliver pizzas and tacos and burgers and stuff to everyone he gets high.
