Special Abilities

Built-in Weaponry (Ex): The TX-1 is able to form one or both arms into a weapon, typically a plasma cannon or flame thrower, although it can produce a high-speed molecular saw-like blade in order to cut through almost any material with ease.  The Plasma cannon is far more powerful, but it has the limitation that it can only be fired once every 3 rounds, whereas the flame thrower can be used every round. Optionally, the TX-1 can morph its arm into any type of firearm, provided that it is energy-based.  Using such a weapon will still have the same once every three round limitation, unless the TX-1 manually inserts a power cell, or in the case of projectile weapons, a magazine.  Changing the weapon takes time, a number of equal to half the level of the weapon the TX-1 is imitating.

Detailed anatomy files (Ex): The TX-1 has detailed files of humanoid anatomy. As a result, it automatically gains a damage bonus equal to half the Terminators CR rating (rounded down). Also anytime the TX-1 gains a critical hit, any DC save increases by +2.

Electrical Vulnerability (Ex): The TX-1 is rather vulnerable to electrical and magnetic-based attacks. When the TX-1 is hit by electrical attacks, its natural DR and resistance is automatically reduced by the weapons level, and any save involved has its DC increased by +2. Magnetic-based attacks also cause the nanites to become temporarily inactive, removing the ability to heal damage (1d6+4 minutes, no save) and it cannot create weapons with its nanites or body.

Hijack Machines (Ex): By touching any type of vehicle or machine, the TX-1 can take control of it. The TX can control up to 5 machines at a time using this ability. It takes a number of rounds equal to the level of the machine in question to take full control of it, although if it attempts to take over a AI or android, the target is allowed a Will save (DC 22) or be taken over. With sentient or AI machines, this will last for 1d10+6 rounds, at which time the machine is allowed a new saving throw to resist the effects. Once a non-AI or sentient machine has been taken over by the TX-1, it is under the Terminator’s full control until it, or the TX-1 is destroyed. The TX-1 must be physically touching the machine in order to hijack it, but once it has taken control, it no longer needs to maintain contact. Any machine that has been taken over by the TX-1 must remain within 500 feet of the unit, or control is lost.

Hyper-Alloy combat chassis (Ex): The skeletal structure of the TX-1 is constructed of a special alloy, making it very strong and resistant to damage. As a result, the unit gains a DR equal to its CR against all physical attacks. Furthermore, the unit gains a +2 to all Fort saves.

Morphic Weaponry (Ex): As a standard action, the TX-1 can morph one or both arms into any type of bludgeoning, piercing or slashing weapon. It takes a standard action for the TX-1 to reform a regular limb, or create a different type of weapon. When using this ability, the T-1000 has a reach of 15 feet. 

Regeneration (Ex): The TX-1 is fully capable of regenerating damage it sustains, even from energy attacks, at the rate of 10 per round. This cannot be done indefinitely though, as it can only regenerate a maximum of 100 points of damage before it needs to replenish the nanites that make up its body.  It cannot regenerate electrical damage through this manner, however, as it temporarily disables the nanites inhabiting the TX-1’s body. This effect will last for 1 round per 5 points of electrical damage sustained.

Semi-Fluid Form (Ex): The TX-1 is partially composed of a swarm of Nanites. As a result the TX-1 can morph its body to take on the appearance of any being it has had physical contact with, becoming a perfect replica of that individual, gaining a +20 to disguise checks. Changing shape is a standard action.


Although the T-1000 terminator proved to be exceedingly effective against the targets it was sent up against, the amount of resources and time required to create a single T-1000 proved to be almost too much for Skynet to consider.

As a result, Skynet turned back to the proverbial drawing board, and incorporated the nanotechnology from the T-1000 into a brand new series of Terminators, the TX series.

The outer layer of the TX is comprised of the same nanotechnology that made up the entire T-1000 but it was bonded to a T-900 chassis. This gave the new Terminator unit the ability to change its shape, allowing it the same ability to disguise itself and infiltrate the resistance bases in order to wreak as much havoc and destruction as possible.

Unlike previous models, the TX-1 is capable of changing one or both arms into ranged weapons.  This has the advantage of removing the need for the unit to carry around conventional weaponry, although it is fully capable of using any type of weapon it can get its hands on.

Also, unlike previous models, the combat chassis uses the most recent carbon-alloys created by Skynet, making it exceedingly resilient to all manner of damage, be it from conventional weaponry or energy weapons, making the TX-1 very tough. Combined with the nanites ability to repair damage, taking down a TX-1 is exceptionally difficult to destroy in combat.

Also, if the TX-1 has a weakness, it is electricity and magnetic-based attacks. The typical resistance is reduced, and magnetic-based attacks interrupt the nanites ability to function properly.

Unlike previous Terminator models, this particular Terminator is able to resist any possible hacking and potential reprogramming by resistance forces. Even if the body is temporarily disabled, a portion of the TX-1 AI is kept separate, with only one goal – to fight back against possible hacking. Also this gives the TX-1 excellent skills when it comes to using and interfacing with computers.
