Appearance:
The
Tholians are believed to be non-Humanoid.
"Future Tense" [ENT]
They appear as multifaceted
solids. "The Tholian Web" [TOS]
It has
an angular orange crystalline exoskeleton (that can be used as a short-range
transmitter), two arms
with three mutually-opposable
fingers each, and six legs. Tholians (according to Mirror-Phlox) are
"its,"
with both male and female characteristics; (but
they can still insult a human's "maternal ancestors.")
"In a Mirror Darkly" [ENT]
Physiology:
They
maintain a very high internal temperature on thier ships (over 200 degrees).
"Future Tense" [ENT]
Its preferred temperature is ~150°C; below
50°C it shatters.
"In a Mirror Darkly" [ENT]
Culture:
Tholians
are extremely xenophobic and tend not to venture far from their home system.
"Future Tense" [ENT]
Tholians tend to be agressive, territorial and
extremely punctual beings who do not
welcome intrusions into their space.
Tholian silk - Tholian silk is highly prized and difficult to
obtain.
"The Way of the Warrior, part 1" [DS9]
Language:
The Tholian language consists of
dolphin- or insect-like squeals, clicks and pops. The UTs of 2152
seem unable to translate it; instead, there is only a
post-translation of important phrases. The
native
polyphony is followed/overlapped by a curt English translation.
"Future Tense" [ENT]
History:
2152,
autumn: They demand the derelict pod from the future that Enterprise
has brought on board,
and warn of "dangerous temporal
radiation". When Archer refuses, they lock on with a "tractor beam".
They fly off and the Archer is attacked by Suliban
ships. He makes a dash for a Vulcan combat
cruiser
only to find that it has been disabled by the Tholians, whose 4 ships now engage
the Suliban.
After the Tholians have defeated the
Suliban, Archer sets a bomb on board the pod and releases it.
The Tholians grab it with a tractor beam and disarm the
bomb, but then the timeship disappears.
Probably pulled
back into the future after their homing beacon was activated. The Tholians
exit.
"Future Tense" [ENT]
The Mirror-Tholians wanted to lure a ship from another universe, so they
detonated a tricobalt device
near a "dead star," creating
a rift, into which they broadcast a distress signal. The Defiant answered.
"In a Mirror Darkly" [ENT]
2268: The USS Enterprise encountered the Tholians whilst it was
investigating the loss of the USS
Defiant in an
interphase region. The Tholians demanded an explanation for the Starship's
presence,
and initially agreed to allow the Enterprise to
remain in the area. When the ship was unable to provide
proof of the Defiant's presence in the area the Tholians attacked the ship. The
Enterprise proved
militarily superior to the Tholian
vessels, but was almost trapped within one of the forcefield webs -
a system designed to enclose a vessel within a network
virtually unbreakable strands.
"The Tholian Web" [TOS]
2353: The Tholians attacked and nearly destroyed a Federation
starbase, killing all but one of its
complement.
Riker's father was the sole survivor of the Tholian attack.
"The Icarus Factor" [TNG]
2355: Tensions remain high enough that Starfleet routinely
trained against Tholian warships in
simulations.
"Peak Performance" [TNG]
It was feared that they might
become involved in the Klingon civil war.
"Reunion" [TNG]
2371: A Tholian ambassador visited Deep Space Nine. At
Jake's instigation, Odo claimed that Nog and
Jake had
been seen breaking into the Tholian ambassador's quarters.
"Life Support" [DS9]
2372 (stardate 49175): The Founders detonate a bomb at a
Federation/Romulan diplomatic conference in
Antwerp,
killing 27 people, including the Tholian Ambassador.
"Homefront" [DS9]
They are renowned for their punctuality. Kasidy Yates was to rendezvous with
one of their freighters to
deliver medical supplies, as
they had a viral infection on one of their colonies.
"For the Cause" [DS9]
They had signed a non-aggression pact with the Dominion.
"Call to Arms" [DS9]
Ships:
Ship [ 2 ]
+ TOS "The Tholian
Web"
Freighter
+ DS9 "For the Cause"
The Tholian ships of 2151 resemble the "Tholian Web" models. Tri-axil
delta shaped. But while the
TOS-depiction made them look crystalline,
these are clearly metallic. Each lobe has two (on each side)
warp-blue-glowing triangular features (implying a tri-lobed warpfield), and
(on its aft face) a single
yellow-glowing quad (impulse?). They can
emit a green tractor beam, a blue systems-disrupting pulse,
or [weapons
color?] -- and can easily outfight two-to-one Suliban opponents. They
enter warp with
a yellow-tinged warp-burst. In length [assuming no
funny perspective], it's a bit shorter than one of
ENT's nacelles.
4 ships showed up trying to acquire the time-ship which
Enterprise had come across.
"Future Tense" [ENT]
The mirror-universe web is shaped like an icosahedron, and is deployed in
less than a minute.
