The Time Brigade
Mankind discovered pluridimensional travel late in the 35th century. Earth's Supreme Council created the Time Brigade. Most of this was the work of the Twelve, or the Founders, a secret group of immortals, inheritors of the science of Mu, the legendary fifth planet destroyed circa 65 million years BC. The leader of the Founders is Kobul-Shan. The Brigade is nominally under the leadership of Admiral Hagan, but is really managed by the Thumb, an artificial superintelligence programmed and monitored by an elite corps of Chronoprogrammers.
The Time Brigade is responsible for the monitoring and control of the pludimensionality of Earth in a segment of of the time-space continuum known as "Sector Rhamno". This spans our galactic quadrant, six billion years from the creation of the Solar System to some unspecified date in the future, circa 1,000,000 years A.D., and all of its alternate timelines. While the origins of the Brigade are known, its ultimate destiny remains unchronicled. In the 41st century, the Brigade functions with teams of four operatives, called a "Hand" since it reports to an artificial superintelligence known as the Thumb. A Hand is comprised of one Coordinator and three Agents. While Coordinators tend to originate from the 40th century or later, Agents are recruited throughout time.
The Hand 28 is comprised of Khanor Rhi (Coordinator, former chronoprogrammer, 40th century), Varna Zelton (time sensitive, former student of Khanor, 40th century), Jason Spell (former archeologist, 20th century), who replaced Anthony Brent (deceased), Minus-3 (augmented ape), who replaced Rock Klammers (memory erased, returned to his own time).
Its allies include Judge Adila Sullivan, Sigrid Lars-Irvenmsky (History), The Twelve (throughout history, Moloch / Balthazar / Ptath / Altotas / Faria / Kobul Shan, Count Saint-Germain, Cagliostro, Pharaoh Imhotep, Atlantean Tatamoua, 18th century Australian rancher John Bradcliff, Karundan Minister Tomac-Ale, Professor Swan, Wall Street banker Eric Bonfield).
Its enemies include The Chronophage, The Cathedrals (alien lifeform), The Vadirian Hegemon, Rodrik (renegade chronoprogrammer, also Khanor's brother), Rosko (Time Pirate), and Mister B.
It's based in Los Angeles, Terra, and operates a Penal colony (Psibloc) on Callisto. The Brigade uses bubble-shaped chronospheres (temposcaphs) that can be remotely controlled through micrtro-monitors to travel through the space-time continuum.
Some of the Hand 28's most notorious missions include its intervention in biblical times at Sodom and Gomorrah, the Cathedral Wars, its battles against the Chronophage, its failed attempt to prevent the destruction of Mû, and its recent operations to stop Wampus from creating an alternate dimensionality in which Earth would have belonged to the Great Mind.
More recently it defeated the Chronophage when it tried to set up two alternate time lines involving Camelot and the Holy Grail; it helped the Strangers and Dick Demon destroy Kera before she could reduce the Earth to cinders in the era of Atlantis, and teamed up with Dragut, Scarlet Lips and the Guardian of the Republic to stop the Necromancer from preventing the settlement of the New World by Europeans.
In addition: A back-up story featuring the Time Brigade entitled "The Time Killer" was published in Image Comics' STRANGERS Nos. 3 & 4.
