I’ve seen almost no mention of the Harbinger linked to being a Yanme.
Like many, my first thought was a Prelate but the fingers, parts of the body, and mainly the face were quick reasons to move on from that initial reaction.
The reason I quickly shifted to Yanme is because I’ve found them to be a facinating species and have been waiting for when they could be dove deeper into of which prompted me to link a few things right away.
The hands… while Yanme can have a big variety of types that could have variations on the amount of fingers and even hand structure, in the end I have seen pictures of Yanme that have 4 fingers and the exact same kind of structure.
The face/head… is very insectoid like. The eyes and how the mouth/chin come to a smaller point. The head on the Harbinger is big which is actually similar to Yanme.
The feet… this is a big one… seriously go look at a Yanme’s feet and then go look at the Harbinger’s feet in several different angles. They are very similar in how the legs hang in the air and how the feet curle back.
The basic body structure… is similar to what you would find with a Yanme. Again, Yanme have a variety of body structures so it’s not going to be exact but you can see correlations across multiple areas of the body.
To be honest… this could be a Yanme Queen. I’m not 100% because we have not had a true visual depiction of what a Ya me Queen looks like although there are some descriptions but again nothing that feels truly definitive. In the end they are considered VERY smart and can be a force to be reckoned with. For the longest time after I’ve learned about a Yanme Queen, an insect hive queen, the thought of that being brought into the story somehow intrigued me.
Another quick few notes…
-In the comic “Rise of Atriox” there was a portion of the story where a Jackle/Skirmisher scientist invented a device that minced the sonic tones of a Yanme Queen that allowed him to control Yanme soldiers. Atriox defeated the Skirmisher scientist and he also destroyed the device. To me, there isn’t a direct link here but admittedly stretching a bit I could see hypothetically it could be linked. This scientist was part of the Covenant and hated Atriox caling him a traitor of which is why they fought. Anyone that knows Atriox knows his strong hatred for the Covenant for how they treated not only him but many of its members throughout society. The Yanme Queen I would imagine could have similar feelings towards the Covanant. She didnt want to be involved or connected to the Covanant but agreed to allow some of her Yanme soldiers to be part of the Covanant of which is why you see them in Halo lore. I can imagine that the Yanme Queen, like Atriox, eventually became resentful towards the Covanant with how they treated some of their own kind of which I’m sure Yanme weren’t the most included and respected of species within the Covantn for various reasons. Having Atriox destroying a device that mimicked the Yanme Queen’s signals would be a very appreciated and respected gesture towards her thus being another reasons for the Harbinger (Yanme Queen) to work with Atriox’s Banished.
-Some may forget but when Cortana was going all crazy in the end of Halo 5 and caling out all various species to join her, she did not include the Yanme’e in her list of species that she offered to fall under her protection. Why? Nobody is exactly sure. It could be general disgust/distaste or it could be that she knows they are not worth the time for various reasons. Either way, this could possibly be seen as an insult to the Yanme, a rejection of sorts. Different yet similar to how Atriox felt from the Covenant, rejection and abandonment. The two story parallels would make for a similar rooted background that would give each other somewhat similar mindsets. Again, it’s sort of a reach but I’m trying to see how things hypothetically could be connected.
-Finally… look at those ‘new flying enemies’. Those again look different yet similar to Yanme. Look at the feet and body structure throughout. Also, some may point at the jetpack like machines on their back and say that the Ya me dont have those they have wings. What most dont realize that the Covnant had to add structures to their backs to allow them to have the ability of temporary flight. It has something to do with the gravity being different on most places compared to their homeworld. So it’s not a stretch to think this is just their own version of ‘assistance’ to allow these massive sized bugs to fly. The previous added 'assistance to Yanme wings from the Covanant only allow temporary flight so maybe this is their solution for longer last flight. Who knows… I’m trying to justify the difference. Still, you can see that the Harbinger and those flying enemies are connected. They have the same design cues on their armor and again their body structure is practically the same.
All in all… this could be a totally different species. However, there is just enough there to give the Yanme’e species a really good consideration. The Harbinger really could be a Yanme’e Queen and we really could see that species brought more to the forefront which only enriches the Halo universe more which I’m all in favor of.
Will be interesting to see what the truth is. I may have left a few details or connections out but overall that is my two cents on who the ‘Harbinger’ is and right now my money is on she’s somehow connected to the Yanme’e species and could very even possibly be a Yanme’e Queen.
