My theory on Tarn
It would be under a read more but I’m posting from mobile so I’m giving you a quick warning for some possible spoilers.
So let’s get on with it:
I’ve read in a few posts in the tag about Dominus Ambus being Tarn and at least one saying that Skids could be connected.
Where I may think they could be true, I’ve noticed something about Tarn’s frame.
To me, he looks very similar to Roller from Shadowplay. Both are quite bulky and huge. I think their helm designs are very close together if you just stick a decepticon mask over Roller’s face. I would attach pictures in comparison, but again, I can’t figure out the mobile app fully. Plus, connecting Skids in, maybe he remembers something that Roller listened to (the emphyrian suite? I think), since we first saw Roller watching various TV screens. Maybe he has a thing for music as well?
And, Roller worked closely with Orion Pax / Optimus Prime during Shadow play. So maybe he is also the Agent, working closely with Optimus Prime, rather than some special ops recruit? But then again, I doubt Optimus would ask someone to go into the DJD, let alone ask a friend to do it.
Tarn seems like the less violent one out of them all. Yes, he’s addicted to transforming and has his little sadistic way of taking it. But the most damage I can recall him doing is just shooting the victim once. The rest rip them apart, melt them, make them wear their face, etc. Which grounds everyone’s theory of Tarn being the agent.
That’s all I have with my theory and its not very good in explanation but I may do a comparison on their frames if I can later on. I’m just adding to the various theories going around. Adding my little ideas to the fandom’s collection.
