I have been looking or browsing the Internet to see any new things about Halo 4 but every once in a while I find something about a species called Nelkrons. I am not sure if they actually exist. However I was able to find a description on them.
The following is quoted: "
Nelkrons are an ancient enemy of the fore-runners, but were eventually defeated and all trapped inside a giant prison until the halo array fired which freed them.
The nelkrons are biomechanical life forms with the power to convert energy to matter and matter to energy at will. They are able to mutate into any form they want, but their appearance generally esembles a mechanical humanoid with a birdlike head. Somewhat similar to the myrs from magic the gathering."
On other sources I have heard that they have re-populated on sigma 7.
Again I am not sure if this is true or if they even exist but if you have any information or here say about them please post.
Also here is a shadowy figure/image I was ale to find I am not sure what is is. Also look closley at image and study for a few seconds it is a little hard to see. You should not have any problems though.

If they were the new enemy I believe they would look something like this which is a Myr from magic gathering cards:
