Which Shivan theory do you believe to be the 'correct' or most plausible one, or the one that you just like the most.
The Shivan Manifesto
The Shivans are energy beings and wish to stop all races from using subspace, as every jump causes a tear in subspace's skin, slowly but surely destroying it. They captured Bosch simply because they thought there were captive Shivans aboard the Iceni. They also feared that there was a fleet of Colossus juggernauts, and created a massive subspace portal to run away from the GTVA. Their home is 'Cocytus,' a hive set inside subspace.
The MindGames Theory
The Shivans are a race that is being controlled by a more intelligent and powerful race called the 'Starborn'. Shivans are there to destroy all those civilizations that become to powerful. They are also part of the 'show' called the 'Great Game.' Bosch was under the control of the Starborn, who made him contact the Shivans and tell them valuable information about the GTVA. However, the Shivans are now aware that the Starborn are controlling them and attempt to destroy the Capella star, killing all the Starborn on (in?) it.
The Reciprocity Theory
The Shivans are fighting against another race, the Nightmares. Both have been fighting for such a long time that they have forgotten everything and are just killing machines. They destroyed Vasuda Prime because there was a Nightmare vessel hidden, and were on their way not to Earth, but to Mars, as there was also another Nightmare vessel there aswell.
Mad Bomber's Theory
Shivans are sensitive to massive subspace disturbances, they had destroyed the Ancients because of their use of Knossos portals. 8,000 years later, the Vasudans and Terrans had collapsed the already-unstable Talania Jump Nodes, attracting the Shivans. The Shivans then came to investigate when they ran into the Vasudans and Terrans.
Ngtm1r's Theory
Conflict draws in the Shivans. The Shivans killed off the Ancients because they were fighting other races. The reason they had not come sooner was because the other civilizations the Ancients killed was because they couldn't put up a fight. But there was one that fought reasonably well, which drew in the Shivans. The Shivans, 8,000 years later, find two new species fighting each other. They attempt to wipe them out but fail. 32 years later, the NTF insurgency breaks out. The Shivans want to stop the conflict and so want to destroy the NTF. They first encounter the NTC Trinity, which opened fire on them. This angers the Shivans, and they want to kill of the NTF. They send the SC Rakshasa to have a look around. However, they encounter the Vigilant, and thinking it is a NTF ship, open fire on it. The GTVA then throws out the Carthage and Dashor, destroying the Rakshasa. Shivan forces deploy the Ravana, but it is destroyed quickly. Next, the GTVA push forward once again, and a Vasudan patrol attacks a number of Gas Miners. The Sathanas then arrives and annhialates the Vasudan force. However, the Sathanas is destroyed by the Colossus, forcing the Shivans to deploy the Sathani fleet. However, one Terran ship is attempting to communicate with them. They agree to communicate with Bosch. However, a panicked crew member shot the Shivan bording party, triggering the masacre. After Bosch boards the transport, the Vasudans arrive and destroy the second Azrael. With the communications with Bosch, the Shivans learn of their mistake of destroying the Vigilant. Instead of fighting the GTVA, the Shivans wish to make a sign that they are, "Bigger, meaner and that we will kick your ass." They do this by blowing up the Capella star.
