For future aspects of my Shield and Sword project, I wanted to nail down a visual for a Forerunner warrior that everyone might agree on - a sort of balance between all the visions we have in our brains. This sketch is the latest, and is definitely pulling a lot from Bungie's concept of a Warrior form.
You can check out some earlier sketches and the discussion that led to this design here: [link]
I don't know about this being a forerunner as this look more like a human then a forerunner, then again we don't know much about how forerunners looked other then they can be tall and that they might be related to humans, well this might also be human armor from the human forerunner wars. Looks badass tho.
