Early 2014, the Halo team was working hard designing the Signature Series Scarab (Felipe_MCX especially) that was due to be released later that year. During the concept stage, the plan was to include a Prophet along with four Brute Honor Guards. This plan was changed along the way, as Halo figures were moving to the new super articulated model and this guy just didn't fit in anymore. However, he did make it to the prototype stage. I found this guy while rummaging through my figure bins. He's a little worse for wear, but has held up pretty well for a 5-year old prototype.
