"Judge Dredd" and "Rogue Trooper" are parts of which comic book concept?
Bad Company
Bad Company (comics)
Bad Company is a comic book concept initially created for British comics anthology "2000 AD" by Alan Grant and John Wagner.
 According to Peter Milligan "Originally "Bad Company" had been devised as part of the Dredd mythos, featuring a Judge who had turned bad and been shipped off to a prison colony on Titan, one of Saturn's moons".
 Milligan, along with regular collaborators Brett Ewins and Jim McCarthy, dropped all aspects of the original concept, keeping only a team of new recruits facing an inhospitable planet and enemy.
 They first appeared in their self-titled strip in "2000 AD" prog 500 (December 13, 1986).
Brett Ewins
Brett Ewins (1955 – 16 February 2015) was a British comic book artist best known for his work on "Judge Dredd" and "Rogue Trooper" in the weekly anthology comic "2000 AD".
Psykogeddon
Psykogeddon is an original novel written by Dave Stone and based on the long-running British science fiction comic strip "Judge Dredd".
 It is Stone's fourth "Judge Dredd" novel, and the third to also feature his character Judge Steel from the spin-off comic series "Armitage" in the "Judge Dredd Megazine". Origins (Judge Dredd story)
"Origins" is one of the longest "Judge Dredd" storylines to run in the pages of British comic "2000 AD".
 Making extensive use of flashbacks, it tells the story of how the Judges of Mega-City One rose to power.
 It was written by John Wagner and illustrated by Carlos Ezquerra, who between them created "Judge Dredd" in 1977.
 The story ran to 23 episodes, and was published from 2006 to 2007 to mark thirty years of the "Judge Dredd" strip.
 It is set in 2129, Dredd's debut story having been set in 2099. The Doomsday Scenario
The Doomsday Scenario is the collective name of a series of "Judge Dredd" comic stories published in "2000 AD" (progs 1141-1164) and the "Judge Dredd Megazine" (vol.
 3 #52-59) in 1999.
 Written by John Wagner, it was the third such crossover story between those two publications, but was the first in which it was possible to read a complete and coherent tale by reading only those episodes which appeared in one comic or the other without having to buy both magazines.
 It was reprinted as two trade paperbacks, each collecting the episodes from one comic.
 When first published it was the longest "Judge Dredd" story arc ever told, at a total of 32 episodes and 279 pages, as well as several prequels and epilogues.
 The story tells of the Second Robot War in the year 2121, but its epilogues wrapped up two story arcs that had been developing for several years: former judge Galen DeMarco's unrequited love for Judge Dredd, and Dredd's bitter rivalry with Judge Edgar.
 The story is also notable for leading to the promotion of Judge Hershey, Dredd's sidekick and one of the strip's longest-running supporting characters, to the office of chief judge. Lawgiver (Judge Dredd)
The Lawgiver is a fictional weapon used by the Judges in "Judge Dredd" and related series that appear in the UK comic books "2000 AD" and the "Judge Dredd Megazine", as well as the 1995 movie "Judge Dredd" and the 2012 film "Dredd". The Pit (Judge Dredd story)
"The Pit" is a "Judge Dredd" story which appeared in British comic "2000 AD" in 1995–1996 (issues 970–999).

 It introduced the supporting characters of Galen DeMarco, Judge Guthrie and Judge Buell.
