The story primarily centers on Captain Kaff Tagon, his mercenary crew, Tagon's Toughs, and their roles as members in a for-profit military organization. Various story lines have the crew swept into conflicts on a single planet, a galaxy-spanning apocalyptic crisis or intergalactic war. In the distant future of
Schlock Mercenary's setting, many changes face Terran society.
Faster-than-light travel is attained, alien races are contacted, and technology undergoes radical improvements. Alien species vary from fairly
humanoid to almost unrecognizable. There are carbosilicate amorphs with no easily definable limbs or organs (the eponymous Sgt. Schlock), eight-limbed Gatekeepers, two-bodied Uklakk, and the unknowable Pa'anuri, beings made of
dark matter. The number of sapient
species descended from Terran stock increased as Earth's genetic engineers refined their craft. Enhanced
chimpanzees,
gorillas,
orangutans,
dolphins,
snakes,
octopuses, at least two types of
bears, and two species of
elephant have citizenship. Genetic enhancement of the
human population resulted in the purple-skinned photosynthetic "Purps", along with general improvements to the population.
Technology As in many science fiction stories, technology forms a large part of
Schlock Mercenary's storytelling framework. Several story arcs revolve around the political conflict surrounding rapid technological change. After a particularly complex or interesting new system is introduced to the comic, its in-comic explanation is often supplemented with a footnote. Travel between the stars is accomplished through the use of "wormgates", large
wormhole generators controlled by the enigmatic F'sherl-Ganni Gatekeepers. Within the storyline of the comic, wormgates are supplanted by the "teraport", a device allowing near-instant travel between any two points, as long as neither point is within range of an interdicting device. In that case, the teraporting object may be destroyed. The F'sherl-Ganni also constructed several buuthandi,
Schlock Mercenary's take on a
Dyson sphere. A buuthandi is a balloon of
solar-sail material around a star. Light pressure and solar wind offset the star's gravitation to keep the balloon inflated, while habitats and maintenance facilities dangling from the inner side act as ballast to balance the sails. Despite their tremendous surface area, a buuthandi provides a disproportionally small amount of livable habitat. "Control cables, millions of square kilometers of slack sail material, and some very clever engineering allow the 'balloon' to compensate for (and, in some cases, mitigate) the mood swings of the contained star." In the
Schlock Mercenary universe, a buuthandi is about 300 million kilometers in diameter. ("Buuthandi" is a shortened form of a F'sherl-Ganni phrase which, after the foul language is removed, can be roughly translated as "This was expensive to build.") Medical technology includes nanobots and both artificial and regrown replacements for damaged body parts. One important item in the comic is the "magic cryo-kit", an illegally-modified device with the capability to rebuild an entire body as long as the brain is intact. In the strip, this is shown as "from the head down", but, presumably, nothing more than the brain is necessary. Conventional legal medical technology is also capable of full-body regeneration, although at a much slower pace and dependent on your
HMO insurance options. The Toughs employ various technologies to protect survival of heads until their owners can be regenerated. An example of this technology is the comedically ubiquitous "head-in-a-jar", which permits a character to interact in a storyline despite
an otherwise-fatal injury. Another is the "nanny-bag", which maintains the severed head and/or entire body of an otherwise mortally-wounded teammate for an unknown length of time. For example, Kevyn Andreyasn's head was sustained for several weeks. In addition to medical benefits, nanotechnology can "boost" soldiers to levels of physical performance unmodified humans cannot reach. Minor enhancements are legal, but extreme military modifications are highly-regulated. Significant examples of soldier-boosting within the strip are the mercenary grunt Nick and the bounty hunter Doythaban, as well as Kevyn in a particular story arc. Computer hardware has progressed to the point that
true, strong artificial intelligence is common, and several artificial intelligences are characters in the story. Weapons technology drastically improved as well. A mercenary's arsenal can include
railguns,
lasers,
non-lethal nanomotive "goober" rounds, and
plasma cannons. Old-fashioned
bullet-firing
firearms continue to be effective against unprotected targets... and are less likely to rupture a hull than a plasma bolt. Energy is a resource literally
too cheap to meter. Anything powered by miniaturized
fusion reactors (which, in the 31st century, are so advanced, they can operate solely on atmospheric gasses), is easily-fueled by massively powerful
neutronium-annihilation "annie" plants—spherical devices generating massive amounts of power by
gravitationally converting mass to energy, a means of power generation made possible by ubiquitous gravity manipulation. One-shot devices (and
bombs) are often powered by
fullerened
antimatter, a carbon-based powder which contains antiprotons at the parts-per-thousand level, and should
never be incinerated. Gravity manipulation is a process as commonplace as modern electronics, employed in starship propulsion and artificial gravity, and weapons and shielding against weapons. Controlled/artificial gravity is referred to as "gravy." Gravitic weapons in particular are common and developed due to their dual purpose—as potent weapons, they can compress matter into neutronium which can then fuel an annie plant. The degree of this control is dependent on the number of projectors. For example, the battleplate
Tunguska was able to manipulate individual limbs, and individual
digits of crew on board the
Serial Peacemaker while smaller ship create nodes of gravity in a few points on the ship and without the same level of control. However, the generation of gravity is beyond the capabilities of the sophonts of the Milky Way, necessitating ships to be constructed around annie plants as sources of gravity to manipulate. These devices and more are built using fabrication technology, or "fabbers". While rare and expensive, possession of one of these portable factories and the appropriate designs allows for the cheap mass-production of any physical item. Several of the mercenaries are trained in fabber design, allowing the company to cheaply produce and repair their gear. ==Main characters==
