| The problem with the Hybrid unit is that Zerg is all bio and Toss is bio+engineered weaponry. I think the mistake we make is that we combine these two. Biologically, the Zerg would MOST likely bipedal (like Kerrigan) with carapace and more likely to have claws and teeth. Possibly better eye sight rather than depending on smells and sounds, sounds as in waves because of the fact most Zerg can burrow and they would need to feel other species above them. Not to mention the Lurker would have to angle itself to spine the enemy to death.
So back to topic, since its already well known that ever since Kerrigan sped up the "reat design according to the agent of a higher power. This could indicate that this was or is close to the ultimate design. Bipedal creatures usually have arms and hands for manipulating their fingers (and possible thumbs). This creates a huge problem for the Terran and Protoss. No longer would they be fighting aggresive beasts, but humanoid features, such as hands meaning the Zerg could adorn weapons, armor, and possibly type on keyboards or whatever systems set up they could wield into combat such as but not limit to spacecraft, landcraft, or lesser Zerg beings; beasts of burden.
