Sonar

Sonar (originally an acronym for SOund Navigation And Ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels. Two types of technology share the name "sonar": passive sonar is essentially listening for the sound made by vessels; active sonar is emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used in air for robot navigation, and SODAR (an upward looking in-air sonar) is used for atmospheric investigations. The term sonar is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic) to extremely high (ultrasonic). The study of underwater sound is known as underwater acoustics or hydroacoustics.

Sonar (comics)

Sonar is a DC Comics supervillain. He first appeared in Green Lantern (2nd series) #14, July (1962), and was created by John Broome and Gil Kane.

Fictional character biography

Bito Wladon

Nestled in the mountains of south eastern Europe lies the tiny Balkan nation of Modora. With a population of four hundred, Modora was relatively unknown to the rest of the world, whose only product was the wool of a peculiar brown sheep found only in that small area. It was not even a member of the United Nations. Modora was sealed off from the rest of the world by Fando the Mad, a leader who believed Modora should be frozen in its past. He burned bridges and barricaded roads to the outside world while making all decisions for his countrymen. One man, Bito Wladon, was determined to change that.

Wladon's parents were deaf, which was a mark of Satan to the superstitious Modorans. By Modoran beliefs, they were not to be killed or hurt, they were to be shunned. Young Bito was a pariah as well, even though he could hear, he was the son of deaf parents. The cruel actions of his community built resentment towards his parents and the outside world. Bito Wladon would hide from the rest of the world in a barn, in which he one day discovered a cache of books, hidden by his peddler grandfather against the orders of Fando.

Dv8

DV8 is a comic book published by Wildstorm. The series revolves around the lives of a group of Gen-Active people (Called DV8, or referred to as "The Deviants"), initially living in New York under the supervision of Ivana Baiul, who sends them on life-threatening black ops assignments.

Publication history

The series lasted 32 issues. The story of most DV8 members continued in the pages of Gen-Active, an anthology-series featuring various Wildstorm characters. Gen-Active lasted 6 issues.

Writer, Micah Wright, pitched a relaunch to WildStorm in 2003, but it was not picked up by the publisher. The artist on the book would have been Mark Robinson (Codename: Knockout).

The title returned in June 2010 as an eight-issue limited series called DV8: Gods and Monsters, written by Brian Wood with art by Rebekah Isaacs. The project is something Wood had been trying to get commissioned for years:

Fictional team history

Rather than saving the world, they use their powers for selfish reasons: to please themselves, indulge in any fancy that comes their way, uncaring about anybody else, and to forget that they are all just pawns to Ivana, expendable to her needs and desires. The members don't like each other, but are soon banding together for survival. This is what stands this book apart from most other superhero teams: they aren't heroes, they are not nice people, don't even like each other and can't even save themselves, let alone the world.
