These are all the races of the Covenant except for the Elites which are in their own section.
About this creation
These are my grunts. While they may look a lot like Saber Scorpion's grunts, I did not copy them. I came up with this design on my own. The grunt on the left is the lowest ranking one, the ones you run into all the time in the game. The middle one is a grunt major who are a bit harder to kill. The one on the right is a spec-ops grunt, these guys are pretty deadly in Halo 1 as they carry fuel rod guns.
This is my jackal. The arm holding its gun came from the new Castle series, I used it so that its gun would be vertical instead of sideways. The shield can be moved so that it covers the jackal's front instead of its side. My jackal can also hold my Covie sniper rifle as they often do in Halo 2, though I don't have a pic of it doing so.
This is my drone, those annoying flying guys introduced in Halo 2. My model is just a geonosian with a plasma pistol, but I couldn't come up with a good design using a Life on Mars alien body, which would more accurately represent the drone's skinny arms and body.
These are my hunters, one of my favorite Covenant. I originally started with Saber Scorpion's hunters, but then I improved them. I made them taller so they would be accurately sized compared to my other figs, I made the shield bigger and improved its shape, and finally, I totally remade the fuel rod gun to make it look like the ones they have in Halo 2 which are awesome.
These are my Halo 2&3 brutes. The one on the left is the Halo 2 brute with a brute shot. I built it like Saber Scorp's new ones, but I made the face and body patterns with a sharpy marker instead of decals which I can't make. The white brute in the center is Tartarus, the boss of Halo 2. The brute on the right is my unique Halo 3 brute major. He is still based on SS's brute but I modified it extensively, adding armor and such to make it look one the new brutes in Halo 3.
This is my Covenant prophet. I hate these guys because they want to kill everybody, also because they look and sound kind of stupid. I made one anyway because I wanted to have all the races of the Covenant.
