I'm going to use some tvtropes links for clarity of concepts & traits jere. Aggressive worked fine in Galciv II when everyone used the same tech tree, but yor are apretty unique synthetic-race & the first 80-100 turns are pretty extremely vulnerable when turn 100-150ish they strap on jetpacks & take a ride on the Xanatos Gambit train. They openly call non-synthetic races mortals & discuss things as if sitting on the early end of a Time Abyss and they freaking know it... It'snot out of the question that individual yor alive in the "today" of the game universe will outlive each and every biological civilization and are lacking in any amount of empathy that would prevent them from openly stating it as a fact, feeling any sort of immortality curse pangs.
Eventually The rocket kicks its second stage boosters into gear & they go from behind to catching up fast & finally orders of magnitude more powerful industrially, economically, influentially, and as a result diplomatically even when far worse in diplomacy to the extent that they are capable of acting in being capable of taking the role of as chessmasters to the Nth degree. Tourism can fuel them (and almost as importantly all of those earlier categories) into the role of a Villain with great publicity with the manipulative bastard card sprinkled liberally in their deck... someone being a nuisance?.. bankroll a third party into war/blockade/etc with them, problem solved.... if not?... do it again. They are so far into the blue & orange morality (where they are done very well) spectrum that I'm not sure "aggressive" is a fitting personality trait any longer.. especially considering it tends to make them flatten themselves before they reach escape velocity

<String>The organic species are easy to manipulate, governed by fear and emotion. We will improve our communications technologies to twist them in the direction we require.</String>
<Label>YorDeeperKnowledge_Dec</Label>
<String>The knowledge of our creators can be relearned. To do this we must look past our own perfection to the primitive organic species that pollute the galaxy. Only by using their ways will we find the deep patterns that reveal the hidden truth of the universe.</String>
<Label>YorPlanetarySpecialization4_Dec</Label>
<String>Optimizing the bodies of the Yor to suit the specific environmental challenges of the worlds they occupy will increase their productivity.</String>
</StringTable>
<String>Modifying our power facilities to include the specialized interfaces used by our creative Yor for their experiments will greatly increase their research capacity.</String>
<String>The gift of sentience takes the form of a Spark, unique to each Yor. Our reproductive creches can create new Sparks using a mysterious process we only partially understand. But we will continue to iterate and improve upon it, as we do with all things.</String>
<String>Unlike the soft and fleshy biological races, bending the surface of worlds to our will is easy for us. Terraforming will allow us to fix the mistakes that natural processes created.</String>
<String>Our nature-correction technology has improved again. The shape of a planet will no longer be left to random chance, and will instead be fixed with the precision it deserves.</String>
<String>Stellar folding drives are the ultimate proof of Yor superiority, bending the fabric of reality to the will of an artificial mind.</String>
<String>The dripping species of the galaxy are also attracted to our internal amusements. We will tolerate and accommodate the ones with the least stench, so as to take their money.</String>
<String>It is perhaps a refutation of the gift of sentience to directly install joy into the mind of a sad Yor. But it is also very efficient. And the sad Yor do not seem to mind.</String>
<String>We will design amusement cruises to encourage the more tolerable meat species to visit our space and leave their resources here.</String>
<String>The biological scum of the galaxy are beginning to realize the majesty of artificial life, and now spit and bleat at each other about the incredible things we do. We will build incredible things specifically to appeal to their limited tastes.</String>
<String>The organics have seen the superiority of artificial creation. Many of their religions now mandate a visit to our space. The resources this provides to us are immense. Annihilation of these enlightened meat men will be deferred.</String>
<String>Yor crew are as comfortable and sentient when away from home as they are at home. The meat species, limited by their meat stomachs, envy us. We have only a few improvements left to make in our Spark support systems.</String>
on and on, very little of their dialogue is actually aggressive as opposed to simple brutal honesty.. with no reason to develop weapons to use against the singularity themselves, yor apply the same brutal honesty towards non-synthetic species when discussing the efficacy of new Yor weapons developments... Perhaps something more fluidic & adaptive than aggressive would be a better fit?
