If you don't have him, do yourself a favor and pick up Warrior Class Optimus from Earthspark.

I got him from the grocery store on a whim a week or so ago and he's quickly become my new favorite desk toy. Mainline figures are usually hit or miss, especially the cheaper options but this one is a real hidden gem. He has (almost) full articulation and a pretty snappy transformation that isn't phenomenally clever or anything but it's impressive how they made a figure feel this featured at this price point. As someone who only really bought CHUG and Masterpiece stuff before, this little guy has made me a lot more appreciative of the inexpensive end of the franchise. He reminds me a lot of the figures I had when I was a little kid, when your imagination did a lot of the work. It's very nostalgic.
