On the Planet Altair IV, there once dwelt a mighty race known as the Krell. Highly advanced, they had created a Great Machine capable of converting energy into matter (and vice versa) instantaneously, anywhere on their world. It allowed them the benefits of technology without cumbersome instrumentation (unless of course you consider 9,200 thermonuclear reactors spanning the planet to power this machine cumbersome).

Despite this they were wiped out in a night. Their Great Machine tapped into their minds, and in some manner to their Id: a dark, primitive side of their personality driven to gratify any impulse or urge. It created monsters from their own subconscious.

Power Boost (Ex): When the Monster runs into something it cannot destroy, it draws upon the Great Machine for more power. As the Monster lacks imagination this takes the form of more damage. Each round the damage done by it's Fiery Touch increases by +1d6 to a maximum of 30d6. If the target appears immune to Fire, then it will switch to boosting Strength instead, gaining +2 Str per round (to a maximum of +36 Str). Likely it would exceed these limits given what it has access to, but for game purposes I have to write down something other than "infinite".

Fiery Touch (Ex): Touching or being touched by a Monster deals 2d6 points of fire damage.

Invisibility (Ex): The Monster permanently has the benefits of the Greater Invisibility spell in effect upon it's person. When in contact with Force effects it can be seen as a translucent figure, and so loses it's invisibility in any round it is targeted by an attack doing force damage, or maintains contact with a construct or object made of Force.

Improved Grab (Ex): If the Monster of the Id successfully hits with it's Claw attack it can immediately make a Grapple attempt as a Free Action without provoking an Attack of Opportunity. If it succeeds it does it's claw damage.

Trample (Ex): DC 50 Reflex Save for half damage (Save DC is Str based).

Frightful Presence (Ex): When the Monster attacks or charges, all living beings within 60 ft. must make a DC 44 Willpower Save (DC is Cha based) or be Shaken for 4d6 rounds.

Magic Immunity (Ex): A Monster of the Id is immune to any spell or spell-like ability that allows spell resistance, with the exception of spells or abilities doing Force damage or that have the Force descriptor.

Vulnerabilities (Ex): If the Great Machine is destroyed (or the person using it is killed), the Monster immediately ceases to exist. Additionally, somehow interfering with the Machine's access to power could weaken the Monster significantly. Any other attempt to destroy it merely causes the Monster to temporarily cease, only to reappear once the Great Machine is used again. The downside of this is that destroying the Great Machine starts a chain reaction that wipes out more than a few planets...

Skills and Feats: The Monster of the Id has all the skills and Feats of whichever person is using the Great Machine to create it where applicable. For example the version from the film has no hands, and so could not do fine manipulation skills such as Forgery or Open Lock, and it's body type may prevent the use of certain Feats. For purposes of skills it uses the ranks and Int Bonus of the Machine's user, despite being unintelligent itself. Using the Great Machine slowly grants the user more mental strength. It permanently increases his Int by 1 for every year of use.

Combat: Fighting the Monster from the Id is nearly impossible, as the Great Machine immediately generates new matter to replace the damaged tissue. No matter what the obstacle, the Machine will simply increase Power until the monster has sufficient ability to overcome it. Fortunately the Monster is neither spectacularly intelligent, nor creative. It simply reacts. It cannot cross walls of Force, even though the machine could simply recreate it on the other side effectively teleporting it. It will simply batter uselessly at the wall. Even so, the only way to truly oppose it is cut off it's power source, destroy the Great Machine, or kill the person who is subconsciously using the Machine to generate it.
