Female Khet

I strongly, strongly hope BioWare don't repeat past mistakes by introducing a new alien species, and only showing one gender, completey ignoring the other with some trite lore excuse (salarians, turians, krogan).

If they chose to introduce another new race like the asari, fine, but make it clear the species is mono gendered.

But if the species is built up of both male and female, there is no excuse for revealing the other gender three games later, in a DLC many won't play.

I disagree. Not all creatures have sexual dimorphism and the same would logically apply to aliens. What they did with Hanar, Krogan, Salarian, etc made sense since they are inspired by creatures that don't have sexual dimorphism. Doing that is better than say slapping boobs on them. 

Agreed.
Only problem is that Bioware themselves said they didn't add females because they didn't have time to add their models in the first 2 games. So to wait until the third game and show the females, only to have them look just like the males would be bullshit. They wanted them to look unique, but scrapped it and just took the easy way out by reusing the male models. 

Female Khets?

They might look masculine to you (I don't really see it)... based on a human. Why should that be taken into account when looking at an alien (or even other Earth animals)? For all we know, all of the Kett we've seen are female, or something else. Or we've seen both already.

I can't agree with this more  It's just plain sad that it took until the third game to see any female turians, salarians, or krogan, and only 1 salarian and krogan, and only 1 turian character in a DLC! Made even more odd since only the turian even looks different than the males... And we still haven't seen any batarians, drell, etc. and at this point likely never will. The only species they did well with was the quarians, which rather coincidentally needed males to be added instead...

Exactly. I shake my head at adding boobs and other human feminine features onto alien females, especially lizard-types. Like, what? Hell, I think they should go further and not necessarily have different voices between the males and females of some alien species, though that's never going to happen. Neither is reversing traits on aliens that would be considered masculine or feminine on humans, like making the females bulkier/larger, but it would be a breath of fresh air and realism.

Which is the lamest excuse I've ever heard, considering they ended up not even making different models for krogan and salarians, but even if they did, it's literally one model to create. One. Used for every female, since the males all share one body as well. They couldn't even do that? Give me a break

And another thing. Say we buy the excuse that they couldn't make 2 models, and that they needed to in the first place. Okay, so then why is it always the females who we never see? Would people think it would be odd not to see any males, but not notice if we didn't see females? Come on. (Strangely, Dragon Age had the same problem with Qunari...)

So yeah, please do better with this going forward

I could see them doing reverse traits actually. For example, if they had a true avian species. Many kinds of birds have the males be the colorful beautiful ones where the females are the duller plainer ones. And other kinds of birds, like birds of prey, have a reverse sexual dimorphism where the females are larger than the males. 

Andromeda needs to have CHILDREN too. Especially when you want to colonize and populate a new galaxy, you better start having children soon. I want to see the arks full of kids all ages.

(No wonder Shepard was so devastated about the boy dying. The reapers killed the only child in the Milky Way!)

Maybe he's the apex sex.

First of all, welcome! 

Thanks for posting that, that's interesting. It now occurs to me that the voice-over might not necessarily be the voice of the Kett in the trailer. It could be somebody else speaking and just cut to look like it's the Kett (if indeed the alien in question is a Kett).

As far as I can tell, this is what he says in the trailer:
"This is incredible."
"I have a bad feeling." (usually said by the good guys in Star Wars?)
"Now I know what makes you special." (Actually, the more I listen to this, the more it sounds like a different voice than the first two lines. And it sounds like it might come through a mask or something - I got a kinda Kylo Ren vibe from it. Any thoughts?)

It would disappoint me, however, if they tried to cop out by saying the Kett didn't have a gender or were both genders or whatever and yet still used an obvious male voice and features. If they truly want to go down the ambiguous route, I'd rather they used a more neutral voice, like the selonians in the video above, than go down the aforementioned "male-as-default" route.  Hopefully that's not the case.

I don't think they can use that excuse anymore to not make changes between both genres in the Andromeda species.
