In the minds of their neighbors, they
are really an empire that covers the entire central region of
the Milky Way Galaxy, a huge interstellar domain. They are saurian
creatures, possibly genetically similar to the Earth species
of dinosaur, the Triceratops. Tough and aggressive, they are
entirely herbivorous (plant eating), and have a high sense of
loyalty to their race. Part of the reason for the Triceratons aggressiveness stems from a cosmological phenomenon
occurring in the heart of their region of space. There is a region
of destructiveness that is gradually spreading out from the hub
of our galactic spiral. The exact cause of this stellar disaster
is not known. The Triceratons deny any problem and laugh off
the idea of a killer Black Hole. However, many stars in the region
have gone nova, and there are accounts of refugees arriving at
the outer Triceraton worlds. The best evidence of the galactic
holocaust are the Triceratons asteroid
homeworlds. Hugh asteroids are outfitted with gigantic ion drives
and become mobile cities and military staging grounds for the
expanding Triceraton empire. Special asteroids are dedicated
to factories, universities, research centers, and even arens
for sporting and gladitorial events. The Triceraton Republic
is now engaged in an ongoing conflict with the Human Federation
("Federat"). A border region consisting of thousands
of square light years has each side jockeying for position. Currently,
the open warfare has subsided, as both sides continue searching
for a weakness or a weapon to solve the impasse. There are many
reasons for the success of the Triceratons. First is their eagerness
to adopt new technology, and their willingness to change their
tactics accordingly. A specific technological strengths that
the Triceratons have exploited thoroughly is their atmospheric
adaptability that allows them to self-mutagenically breathe otherwise
unsuitable air. Some Triceraton agents take Xemorene, a highly
addictive stimulative drug that increases speed and efficiency
of the nervous system, the withdrawl effects leading to heart
failure and death. In the aftermath of the Turtles accidental transportation to Triceraton space
(during which time the Turtles competed in a combat tournament
against four Triceratons in a "Tri-Sports" bout, then
took the Triceratons Prime Leader hostage) upon their breaking
into the TCRI building, three were accidentally transported
along with the Turtles back to Earth (TMNT Vol. 1, #6
& 7). While one of them was captured by DARPA (TMNT
Vol. 2, #9 - 13), and another, Zog, went into hiding in
the sewers until Raphael discovered him prior to the Turtles second confrontation with Shredder (TMNT
Vol. 1, #19 & 20), the third transported Triceraton remains
unaccounted for. After their accidental sojourn into Triceraton
space and Dhoonib, the Turtles were invited back
to the TCRI homeworld, where they were reunited with Fugitoid.
Almost immediately after they arrived, Gavat-4 Station, an outpost
that had a Transmat link directly to the Utrom homeworld, fell
under heavy Triceraton attack. The Turtles agreed to help them,
transporting themselves to the station and self-destructing it
(TMNT: Guide to the Universe, Shell Shock). When the Turtles
persued DARPA in search of their brother, Raphael, missing after
a conflict with a then-cyborg Dr. Baxter Stockman, they
soon found themselves facing a Triceraton invasion in Nevada.
The cityship that made up the invasion force (it followed the
Turtles transportation signal from when they
were accidentally transported there), falling apart from its
long space voyage from Triceraton space, attempted to ram and
decimate the Earth by slingshooting around the sun and engaging
full Impulse Speed. This attempt, however, was presumably stopped
by Louis Braunzes extraterrestrial-captured
"inter-phasic cannon," which he planned to use to move
the Triceraton cityship out of phase, causing it to then harmlessly
pass through Earths outer crust and re-solidify in the
molten core, vaporizing the gigantic vessel (TMNT Vol.
2, #13). During his three year stay in the sewers, the Triceraton
Zog had evidently begun construction of a Triceraton aircar that
Donatello would later discover and complete, then remodel
(TMNT Vol. 3, #2 & 10). Eight Triceratons Transmatted
to Earth when Leatherhead and his Utrom friend Dr. X tested
their second attempt to build a working Transmat Device to get
him "home" to the Utrom homeworld on Leonardo. The
Triceratons had been looking for the Turtles for some time, and
seized the opportunity to send a commando led by Captain Zak.
Leonardo nearly killed one of the eight Triceratons with
their own firearms, though Leonardo, Michaelangelo, Leatherhead,
and Dr. X had to escape from harm's way. Lured by the homing
beacon sent from the Turtles' aircar, Captain Zak has one of
his Triceraton commandos translocate to the signal, appearing
directly on top of the aircar as Donatello unsuspectingly
pilots it home with Horridus/Sara. The Turtles managed
to fight the Triceraton invasion to its climax, with the invaluable
help and savage force of Leatherhead, who, along with the last
Triceraton standing, was transmatted away to parts unknown (TMNT
Vol. 3, #19 - 21).
