I find it odd that people keep using Megs as a base for Guiltaur when it seems to me that Optimus is the logical choice. Oh well. I got Sixshot a few days ago from HTS and he's really one of my favorites and my first TR Leader. So the oversized face/Brainmaster thing was new to me. It ended up being mostly a non-issue as almost right away I just went to leaving the head in place for every mode. It really is an immense pain (literally, I even ended up poking my thumb one time) getting that head out, in fact the last time I did it, I used a letter opener, plus the integration is virtually useless; no other head looks good and Revolver doesn't look good on anyone either as an incomplete head. Plus like some others here, I am concerned about long time use chipping away at that white paint. So, he's not really a headmaster for me anymore (except as a secret surprise), but that doesn't detract in the least, he even can copy the original box art/tech spec art rather well. After a quick check to the anime, his seventh mode, Wingwolf is very solid and nice looking Despite being a Titans Return figure who I don't use the TM/Headmaster gimmick, it doesn't mean he's not compatible or has his uses there within the "play pattern", his APC mode can transport the troops: That's 7 TM's he's moving around, plus Revolver himself who's still the head/face for 8 just with the base configuration! What's more is the ports allow you to really load him up as to your desires to make him a block of TM transporting terror! 13 Titan Masters (not including Revolver in the head)! I could've gone further, or used the actual TM gadget partners, but I wanted to go with quickly compatible guns that could seat and offer up some forward facing firepower. I used Sixshots on the front because it jacked up the clearance on the ports next to the windshields, so I could put more guns there. So yeah, Sixshot is definitely part of the TR gimmick/play pattern, you can go "More Dakka" to your hearts content and use him as an APC of death.
