If the Sangheili, Unggoy, Kig-Yar, San 'Shyuum, Jiralhanae, Lekgolo, and Yanme’e were composed, how do you think they would look?
As in made into Prometheans?
Exactly the same. Its not the species that makes what a Promethean looks like, just whoever designed that particular model. The Warrior-Servants that made up the original Prometheans looked just like the ones with Human memories.
The composed mind is basically just to power the AI, otherwise it truly has no effect on the Promethean’s appearance.
The knights always have forerunner skulls, despite being human. Its unlikely there are variants for different races.
They might just have different looking skulls faces, unless the model is the same.
The model is the same since both Prometheans and Humans were turned into Promethean AIs.
They would look no different. Both humans and Forerunners have been composed into Knights, yet there is no visible difference between them.
But that does give me an idea. What if, in Halo 5 and the Ur-Didact returns, he could compose some members of the Storm Covenant, and give them different Promethean models. That could give us a couple of new Promethean classes; perhaps they could even have their own version of the glowing skull depending on the species.
There would not be any difference between composed species, as only the subject’s mind is extracted, their physical appearance is destoryed.
That being said, the appearance of the composed being is decided by the person who creates the artificial body for the being. You could have Promethean Knight’s composed from Grunts and they would still have the same appearance.
