As the title said.
We saw of a Screenshot of the X'or, a Arthrox ship. We know about the X'or as Insect-like Robots that seek knowledge from a (probarly) "war-like" race that also seek knowledge by destroying others.

Arthrox is a new mistery, as far as we know, they are Organic race, completly oppossed to the X'or, but what face they will show, an aggressive one, an peacefully one? or just they want a war and bring races to extinction just for fun like a sport? for need? or they jump to a bloody war just for... knowledge?

What physical form will have an Arthrox? a monster-like creature, humanoids (lizards probarly), thinner aliens, or they are their own ships? so many question about this race.

all we can do is wait until it comes out an official information about this race. this is just my questions about this race, because, the races owners of the bioships are an aggressive (mainly mindless, controlled by a hivemind) race with their need of "comsume" and "feed" from others races.

Sorry for my english...

I was pondering similiar, and is mindly anoying that so many devs and writers give this almost zombie like mentality to 'Organic' species. They corrupt, consume, build up and move to another location. Like Zerg from Starcraft or Tyranids from Warhammer 40K and today closest the Alien-anyone seen Prometheus I guess its old idea, but me being Babylon 5 fan I really like what JMS did with Vorlons. A species that transcended their organic origins, evolved into a beings of like pure energy that almost nostalgicly concentrated on organic techs. Well, I just hope Arthrox arnt typical stereotipical Zerg like species and I am looking forward to learning more about their ancenstry

There will be further information about the Arthrox soon. I can say for now that they are not like the Zerg or the Tyranids.
