What alien species did you want to know more about?

[Bootlebat]

I've always been curious about the five from #25, mainly due to the unusual choice of name. Maybe they have some relation to the 333s in the Ellimist Chronicles?

[RYTX]

Well, obviously the 333s over time gave rise to the Five, which the Andalites think they wiped out but it turns out some bit of them survived and became the One.

I kid, but...maybe I don't

Pemalites, for sure, I never got a good visual on what they looked like, and of course it'd be interesting to see there history.
The Nesk, curious what they've been up to for the last 65 million years.
Whatever the species the Drode is, and Crayak for that matter. And the thing that kicked out Crayak way back when.

I always found it weird that we never got more of the Taxxon POV, that could have been interesting to see them separate from the Yeerks.

But above all, left to one, the Skrit Na. My god, the Skrit Na, where, when, why, what. Arguably the catalyst of every major event in the series, but I we ever get is "worthless species, the Skrit Na."

[DinosaurNothlit]

How about the Kelbrid?  Granted, they are only one loose end at the end of the series out of many, but all we ever get is the fact that they're apparently badass enough to make the Andalites scared of them, they might be xenophobic (that was my take, at least), and a possibility what their ships might look like.  Just enough, of course, to make you want to know more. 

But I have to agree with all RYTX's answers, too.  Didn't even think about the Skrit Na, but that's an excellent point, right there.

[NothingFromSomething]

The Kelbrid were pretty much just an endgame piece of the puzzle, though, we didn't need to know anything about them because their purpose was just to exist, as a one-book plot device, a deterrent.

Like The One.  He's a big absorbing-entity guy that kills all the Animorphs except Cassie.  *Shrugs*  Imagination takes over at that point, and it probably should, there's no point in detailing this stuff unless they're a recurring idea that needs depth.

[Bootlebat]

I've been curious about Kelbrid also. For some reason I always imagined theyd look sort of like griffins.

[AniDragon]

Pemalites for sure (but you all knew that about me, lol). I'm also a bit curious about the Generationals from the Ellimist Chronicles. I used to have a lot of headcanons about them, but I never wrote them down and kinda forgot about most of them?

[Chad32]

The Onganchics, maybe. I believe it was a species that had no planet, so the Yeerks couldn't conquer them for being spread out among colony ships.

Although there are some species mentioned once, early in the series, that are never mentioned again. The Sstram and the Mak that apparently got conquered like the Hork-Bajir and Taxxons, but we never see any.

What did you think the generationals would look like just wondering?

The Ssstram have interested me for ages, mostly because their name starts with a triple consonant and that's just weird.

[Bootlebat]

me too. I always thought they would be snake or lizard like based on their name

I hadn't gotten that far, lol. Most of my headcanons involved how I would go about writing a fic from their point of view when they're implied at having a collective consciousness, like the Howlers.

     1) Ssstram, 2) Mak, 3) Nahra (spl?). I don't know why, but these three, with the Onganchics as a fourth, interested me for whatever reason. I intended on including them in a continuation of the series that I never got around to continuing after writing Animorphs 55.

Actually, I've planned out the first few books of a continuation (55-60 so far), and the Mak play quite an important role. The Ssstram are described a little in my current fic, The Main Course. I was always intrigued, so I thought I might expand on the a little in my writings.

I rather liked that, actually. The Skrit Na are (IIRC) the little grey men, so it seems fitting that they were kept mysterious. I don't think they were ever meant to be elaborated upon.
Agreed on the Pemalites! And the Andalites themselves sond fascinating. There were so many valuable opportunities to develop their culture, but we only really get #33 and parts of TAC.

Would've been nice to know some more about the Yeerks who were left behind on the home planet, but I guess the series didn't allow for that.

[NothingFromSomething]

I loved the Skrit Na.  Don't think they really need to be expanded upon though, they're just crazy mad-scientists-slash-pirates/junkers with a wacky reproduction cycle.  Who mutilate cows for fun and crazy people in Nevada/Arizona rant about constantly.

Coolness.
