The Tyranids from Warhammer best the Zerg from StarCraft in any sense

Counter-Adaptation: The Tyranids are a manifestation of the destructive ravenous unpredictability of nature in a universe that knows only war. The Tyranids are extragalactic beings that have more than likely consumed countless galaxies before the milky way, their ships are living creatures whose innards are living breathing ecosystems. That is the home of a Tyranid, itself. Hundreds of world had already fallen to the Great Devourer in the WH40K universe, each world as different as it is diverse from each other, and the Tyranids consumed them without faltering. Already, with them not being created in the way the Xel'naga created the Zerg, the Tyranids are a natural destructive result of any world regardless of environment. Pods of dormant Tyranids are found on some planets as well, from scorching deserts to freezing arctic environments, the Tyranids manage to naturally be able to counter the natural elements of any world. The Norn-Queens that guide the birthing of new Tyranid breeds can and does add new traits to Tyranid biomorphs as it see fits. For example, there are numerous different versions of nearly every Tyranid, and in some cases, a Tyranid biomorph is changed almost completely to counter the obstacle that lie ahead. Carnifex's can be outfitted with stronger chitin to shrug off tank shells, or be given an adrenaline gland to make them even more ferocious in combat, or be outfitted with a ranged weapon to combat a specific enemy. Warriors can be given larger and sharper talons or a ranged weapon or even a whip, and bio-titans can be given a large array of devastating improvements. In a battle against the Tau forces in a jungle world, Tyranid forces were slaughtered by Kroot warriors, as a result, the hormagaunts were redesigned by the Norn-Queen and they were able to camouflage themselves and traverse the thickets far better than the Kroot, giving them the advantage over the Tau. Counter-Communication: It is true that both forces rely on psionic/psychic communications, however, my opponent's claim that the Zerg queens have the potential to interject the synaptic link and control the Tyranids themselves, however, Tyranids are not controlled through psychic commands. They are driven by instinct and the will of the Hive Mind. The Hive Mind is an entity in its own right, a being of pure psychic power that embodies itself in Hive Tyrants and is a part of every Tyranid biomorph. As a result, any non Tyranid organism that attempts to tap into the synaptic web is driven to the immediate insanity. This only occurs because tapping into the psychic mind of a Tyranid essentially means connecting yourself to the synaptic web, meaning, you create a direct path for the Hive Mind to enter your mind as well. Due to the Hive Mind being pure psychic energy and a part of every Tyranid alive, the Zerg queens would not have any chance of controlling Tyranid forces, rather, they themselves would allow the Hive Mind into their psionic mind, essentially giving themselves up to the Hive Mind and having the opposite reaction than anticipated. In the case of Kerrigan, much would need to be discussed, she is the most powerful being in the StarCraft universe, but if she were to allow what is essentially a god into her mind, would she survive? The Hive Mind has spread through countless galaxies before reaching the Milky Way, does Kerrigan have truly have the strength to psychically combat a being that spans the universe and has grown in power for Millennia? Counter-SideNote: The Tyranid psychic presence has an odd effect on psychic/psionics in the universe. When a Tyranid hive fleet is travelling, it uses psychic energy to propel itself through space, as a result, a phenomenon called "Shadow in the Warp" happens, in which, wherever the Tyranids go, all psychic scanning and communications are cut off. They carry a bubble that nullifies a psyker's/psionic's ability to see them and communicate with another person of the same power. So, in counter, the Tyranids would be able to surprise the Zerg if the Zerg do not react appropriately to all mental communications being interrupted and nullified for seemingly no reason. counter-Primal Zerg: I to have read up on the Primal Zerg and can honestly say that I was impressed with their ability to absorb abilities from their pray and adapt almost immediately right then and there. However, my opponent thinks the Tyranids are stupid in the sense where they would willingly run into the jaws Primal Zerg. Tyranids test a foe and adapt accordingly, once locating a large creature whose psionic potential is high, the Tyranids would instead attack with an aggressive force. Warriors, Carnifexes, and a Hive tyrant to control the horde would be more than enough to take down the myriad Primal Zerg. Tyranids do not willingly die for the benefit of the species, they attack and keep attacking until they are killed or their prey is. Creep argument: I do not disagree that the Creep would definitely alert the Zerg of a Tyranid presence, however, the mycetic spores are not spores that create a Tyranid environment. Mycetic spores are very large living drop pods the size of houses that crash down on surfaces and vomit Tyranid forces, many have offensive capabilities, although many die on impact, waiting to be devoured by the Great Devourer once the world is taken. Other than being living drop pods, the mycetic spores would not have any direct effect to the Creep.
