The number of things Lobo can say he actually loves can be counted on one hand. He loves his space dolphins, he loves carnage and mayhem, he loves drinking, and he loves heavy metal. In fact, the anti-hero's love for the extreme music genre is so great that he actually had an intergalactic radio transceiver implanted directly into his brain so he could literally have metal playing in his head all day, all the time.
In 1994's Lobo #0 (by Alan Grant, Val Semeiks, and John Dell), it's revealed that Lobo willingly underwent surgery to have a radio implanted into his brain. To be fair, the story was related by a member of a down-and-dirty group of intergalactic bandits running for their lives from the bounty hunter, but the bandit relating the information said that he got it from a book called "Lobo: The Unauthorized Biography" while he was imprisoned on Asteroid-9 for five years, so the authenticity of the story seems legit.
Lobo's Love for Metal Started at a Young Age
Lobo was an absolute monster from the moment he came into existence, going to great lengths to cause chaos and discord in the world around him. He wanted nothing to do with his fellow Czarnians, and he did his utmost to be as different from them as possible. When he was a teenager, he formed a band called "Th' Main Man An' Th' Several Scum-Buckets" for a battle of the bands just to kill them, the judges, and the audience. Oddly enough, Lobo still wasn't satisfied living among the other Czarnians.
Laying down without any anesthesia, Lobo ordered surgeons to implant a radio transceiver into his brain. The surgery was an instant success, much to the dismay of everyone around Lobo. It's amazing to know that at any given moment, no matter what Lobo is doing or where he is, there's metal pumping directly into his head. If the thought of having metal blasting in his brain would make Lobo dangerous enough, the consequences for turning it off are even worse. 1994's Lobocop (by Alan Grant and Martin Emond) is a one-shot comic that explores this very possibility.
Lobo Should Not Be Cut off From Heavy Metal
Being buried in concrete is a good way to interrupt a radio broadcast, and that's exactly what happened to the bounty hunter during Lobocop. Instant rage erupts from the newly formed parking lot, his absolute need for metal pushing his body to absurd levels of power. In short, Lobo is literally addicted to metal, and his withdrawal symptoms are an immediate danger to anyone unfortunate enough to be in his vicinity.
Other characters in the DC Universe have a tendency to either take themselves too seriously or care too much about how others perceive them. Lobo is the exact opposite. The self-proclaimed Main Man is most certainly a rebel of the highest degree, with an equally rebellous soundtrack echoing in his head at all times.
