The Looniverse
The world of the LNH, known as the Looniverse, is an alternate universe much like our own, but with the presence of net.heroes, net.ahumans, and net.villains.
One notable difference, besides the presence of superpowers, is that the vast majority of LNH characters are aware of the fourth wall: they know that they are fictional characters in fictional stories, and often will comment on bad characterizations and ludicrous plot-twists, sometimes talking directly to the audience or their author. Sometimes, the plot-twists themselves come out of fourth-wall breaking. For example, in Gary St. Lawrence's story, The Case of the Clueless Mystery, the characters discover how to defeat the villain by consulting the script. Metafictional concepts such as Comedy and Drama are treated like real cosmic forces.
The Looniverse is also notable for its ability to simultaneously contain mutually-exclusive ideas. In the work of Hubert Bartels, for example, mainstream comic books are treated something akin to movies: heroes audition for the likes of Rob Liefeld and Marv Wolfman and model for the penciller. Other authors treat the work of Marvel and DC as comic books that are products of their writer's imagination. Still others use parody titles to represent mainstream comics, i.e., Justice Mind-Wipers of America instead of Justice League of America, New Adventists instead of New Avengers.
Some characters operate in a world of realistic physics; others operate by the laws of Cartoon physics. For some characters, time unfolds akin to real-world time; for others, all their lives have taken place in "the last ten years". Yet these characters can often meet and team-up in the same time-frame.
