I just came across a forum post elsewhere and I thought it's worth a poll. "Would you display Sentinel Prime with your movie autobots or decepticons?"
Jetfire stands proudly with the Autobots. Sentinel... well he's not standing proudly, but he is with the Decepticons.
I only have one DotM shelf right now, so I have Sentinel in the middle between the Autobots and Decepticons. He's also using HA Drag Strip and HA Backfire, so even his weapons are mixed allegiance.
Right between the Autobots and Decepticons, with his head tilted towards the bad guys as if he has plans. It seemed like the only way to display him.
For me, it's other: my Leader Sentinel is on a shelf alone with Leader Ironhide. My Cyberverse Sentinel is in the middle of my big Cyberverse battle scene. Although he is in the Ark with the Autobots, the way I've got him displayed is meant to show that his allegiance is in question; he's not attacking or being attacked by either side. "Here we are. Fight us now."
I could no longer leave him on the toystore shelf. Now he's on the MISB shelf (for me MISB means I didn't yet have time to properly welcome a TF to the collection and I'm not going to open any of them just to have them opened).
If I had him, I would just throw him in some spot that I had a opening. But I have no plans on getting the figure.
