Why do they kill

@splatterpunk  You know I agree with you. This was the reason I didn't want to say anything but you know I got your back if you need it. I'm pretty sure you can handle yourself just fine.

I'm fine Dr. I'm done with it. No worries but thank you.

Splatterpunk - you got me.  Your intelligence is amazing.  So is your understanding of the Dynamics of being an omnivore.  And we will give you time to look up that word..  8:58pm EST - go

i did not mean to offend I just plainly wanted to state these are Alien creatures and as such we aren't suppose to understand them, I don't think the neo feeding was a plot hole as such.

as far as all that other stuff about hunting in society whether it's needed .... I'm not getting into that to far just that 

i value hunting and fishing and certainly am no "male romper wearing liberal" lol.... But that wasn't my point, I was just pointing out these are Aliens they are and do things we don't understand by definition

Yep, you guys are right.  We should just get our food from the supermarket and try to forget about what happened to bring it there. 

Back on topic...why doesn't the proto/xeno eat?

@splatterpunk    You're welcome

@WonderBoy, I recommend you watch Alien3-The Assembly cut which adds 25 minutes to the movie.

OP, if you remember Aliens, the Alien species does have intelligence and an organization hierarchy.  They seek to reproduce and increase their numbers and view everyone as an enemy to their species.  What came first? The Queen or The Egg?  lol  Covenant makes it seem like the egg came first.

Perhaps the exno does eat. It's just not something they have explored. However, it is clear the neo was sitting down to feast on its fallen prey. As far as the other aliens go the audience was never privy to it because no one ever lived long enough to tell the story. In alien the directors cut Dallas was stuck on a wall with bugs crawling on him. That was a solo exno with no eggs. Perhaps it was storing him for a snack.

use your imagination. I happen to be a creative person so it is easy for me. Author and all that stuff:)

Just because we saw only one form eating doesn't mean the other forms don't.
That said, as was pointed out, this is a genetically-engineered and absolutely unfamiliar species of creature, that's un-finished.

Thermodynamics and energy conversion being what it all is, all the forms must intake food to balanve their energy output, that's just physics, plain and simple.

As to why they kill...the baby Neomorph might have been hungry, probably was, given the insane speed they mature and grow with, that takes a LOT of energy and building materials!!

As they're all genetically engineered, maybe they're all hyper-aggressive, and David has yet to adjust that aspect of them, dial it down a bit??

Just catching up - So, from a transitive standpoint, since I hunt, I am a poacher and a criminal?  Hilarious.

In Alien Directors cut there were not bugs crawling on Dallas... Him and Brett were both in that room and both were being egg morphed is what was happening... This has been confirmed

Blackwinter - that is fair, as we saw the Neo's in their infancy, whereas the proto aged off screen.

Looked like bugs to me. Hmm, fine I haven't seen it in awhile. Then going by that aliens queen is bunk and shouldn't be cannon since the Xenos can turn people into eggs and no queen is necessary. Or it was a scene that didn't work and out was cut. See this is why I want a box set of just Scott's movies. 

Counting the directors cut as cannon then all David needs is one alien and he can morph everyone into eggs. 

Something doesn't seem right...

The nasty remarks about hunting and such, I'm trying not to pursue. I and hubby hunt exclusively with a bow, or slingbow for small game and birds. Neither hubby nor I use guns when hunting, a missed shot clears the area of game, and it just feels wrong to us...impersonal.
That said, we are both very experienced in the use and care of firearms.

Now, before anyone gets 'uppity', stupid and hippy-dippy on me...
I'm a Native American, Blackfoot Nation as is Husband. When I hunt, or when hubby does, we aren't hunting for trophies, we're doing so to provide for our family and for others outside our family who depend on us doing so. It is an integral part of our culture going back many millenia. We do our best to keep our people's culture and identity alive, as will our children and theirs.
And just to say, not a scrap is wasted. Most people shy from eating organ meats and such,we do not.

Thanks.  I was raised on the land as well.  Same type of folk who would have been on the Covenant!

@Blackwinter-witch    That is hunting the way it is intended and I will never have a problem with that. You are Native American that is awesome. This is your land and you shall do with it what you like. Sorry for us terrible white people who came here and stole your people's land. It is something that never should be forgiven, even though we didn't do it some form of our ancestors did. It is unforgivable.

Umm...?  Blackwinter - good for you and your family.  Hunting is an important factor to understanding the value of life, and to teach it as well.  But this isn't the place for that conversation, so if anyone can tell me  how to delete this topic that would be great LOL.

I still think it's curious that we don't see the xeno/proto eat.  They are the poacher/trophy hunters as discussed above.  But whatever.

Well they are engineered from black goo and countless mutations. So possibly they were cross gene mutations of very violent and aggressive killing machines or whatever. They have been referred to as the perfect organism. Maybe David used very aggressive creatures, DNA of creatures or whatever, or maybe it's from the black goo.

Hunting is natural. All living things must eat another living thing to survive. Plants are just as much alive as the wolf that stalks the deer. Mankind was designed to kill and eat other creatures - it is the simple, baseline truth. Nature is, and always will be, red in tooth and claw.

Beyond humans, sharks could be called "perfect predators", but they kill to eat - hence predate..  I would think a perfect "organism" would monitor the food supply and not kill everything asap.  That approach wouldn't be so perfect.  Are they calculating and killing resistors?  That is an option but I don't see this on film.
