I have been regretting passing on Titan Returns Quake. I don't hate the legacy version, but the TR toy is better.

I transformed him back from tank mode yesterday after watching the "Basics" video about him on YouTube and got caught up with how the legs are supposed to collapse back together. Outside of the legs he's a fairly simple bot.

(Skullgrin's lack of a robot head has always bugged me, and more so when I see a custom that shows what could have been!)
