Here's a mod I did to this figure, I took the mace off his mechtech weapon, then I drilled holes in the hands, which are completely invisible in robot mode (yeah u can see them once u transform him and look UNDERNEATH the vehicle mode.
This mod allows him to use a punch pin and use the mace more "show accurate" like.
Then I used a spare Gundam connector that fits the mace end perfectly then I attached some chains to it and a 5mm handle for the other end so he can hold the chains and gave him the new awesome weapon!
I also added more Autobot Insignias to make him look cooler, I'm keeping his back wheels off to keep the bad ass bulky image haha
