Here's the yellow imps now, they are wool covered imps mostly used for cattle and grunts for The Unknows but they are sentient beings with very little intelligent when under there rule, but after The Unknows have left after the war against earth yellow imps have been trying too better themselves for better or worst, Smiz went with the worst after trying and failing horribly too rob the twins the poor little guy didn't even have bullets for the gun, it in fact it was a nerf gun if anything the twins just gave him money too help him but in his culture of yellow imps if someone does something nice for you, you need too return the favorer so he follow the twins around, and Jackson felt bad for him and ended up letting the little guy stay in his apartment with his Sister and Vampre, much too his Sister's disagreement but this means Smiz was vary grateful so grateful he pledged his loyalty too them, of course they didn't know that would happen and now have a little yellow imp following and helping when ever he can.
Also his imp's species height and body are inspired by Halo Grunts, mostly through Master Cheif's prospective where they are small and not the normal big as a human size you see in ODST
