I watched a video on converting the Final Faction A.C.R.M. Figure into a combat droid/walker. Here's the link to the video: https://www.youtube.com/watch?v=Qd8OCjZQhYA
After watching it, I went to the Dollar Tree and picked one up. For the most part, I stuck to what I saw in the video, modifying the paint scheme somewhat. I did add a few items from the Final Faction accessory packs. I also glued the head, arms, and legs so that couldn't move. For a few hours of time and a little over $4, I'm stoked at how cool this figure turned out.
Take a look at the Ranger Class Combat Droid Series TX-281. It's know by the Grunts it supports simply as "Walker".
