===Zerg vs [[Tyranids]]===

Both are races of ravenous, rapidly evolving beasts under the control of a distant supreme intelligence, both use biotechnology instead of tools, most of their units are fast, deadly, fragile and numerous, and they even look almost the same. The last part is no accident, since GW all but copy-pasted the Zerg appearance into Tyranids in 3rd edition, mostly to capitalize on ''StarCraft'''s financial success (yes, they were that greedy and shameless even back then). 

Secondly, while the Tyranid hive mind is their collective consciousness, the Zerg have actual physical entities with emotions and personalities to rule them - from the lowly Overlords, to the Cerebrate, and even to The Queen of Blades after Kerrigan took over control. With that they also get some actual character development and political struggles in their ranks - something 'Nids solely lack as individual organisms are simply tools of the Hive Mind, whose only motivation is to feed. Even though most Cerebrates merged into the new Overmind and were subsequently killed by Kerrigan (and her puppets) during Brood War, the real reason that they never showed up again was that their hierarchy was similar enough to the 'Nids that the Cerebrates were killed off off-screen and cut from ''StarCraft II'' as a way of [http://comments.deviantart.com/1/359035454/2977652201 Blizzard playing nice with Games Workshop].

The Zerg also do not consume entire worlds like Tyranids do. They only conquer and colonize them, which automatically lowers their Eldritch Unstoppable Evil level by half.

There's also a variant of Zerg called the Primal Zerg, which have a strictly more reptilian/mammalian aesthetic and are notably individuals that operate in Packs. Despite being individuals, some with marked intelligence, they're all basically just focused on eating strong prey and surviving and have no ambitions or desires beyond that one dimension.
