Well, this is one of the first times we have ever physically seen all of the Thirteen and it was well worth the wait. However, the one question that remained bouncing around my head all through the episode was which one was which. I replayed the episode several time and thanks to the stills on tfwiki i've had a lot of help figuring out which on was which. Here's the picture for reference (credit goes to tfwiki.net for these): Here's what i have so far: Prima-This one was pretty obvious. He's the one weilding the saber and the in the center of the second group shot. Megatronus (The Fallen)- This one was a bit more difficult to figure out. I think he's the constantly pictured with a glow around his eyes and aura around his body. You can find him directly below Prima in the third shot, all the way to the right in the second, and towards the left in the shot of the Well of All Sparks. Alpha Trion- I'm still not quite sure which one Alpha Trion is. He could be the one directly on Prima's left side (the one to the right for us reading). He could also be seen in the third shot right below Prima's hand and in front of Megatronus. EDIT (thanks to shadow2879): He could also be seen in the first pic. He could be the one in the top center with a visible full cloak. Solus Prime- This feminine bot was another pretty easy one to find. She's the one all the way to the right in the third shot weilding what appears to be the Magnus Hammer and in the first shot the one immediately below The Fallen. EDIT (thanks to shadow2879): It may appear in the first shot she could also be the one in the top center next to Alpha Trion. Liege Maximo- This was also easy to find. He's the one depicted with the horns in every picture. Behind Prima in the third shot, off to the far right in the second shot, and to the left (right for the readers) of Prima in the first one. The Mini-con- I think this one is the one depicted with the blue force field around him in all three shots. He stands out like a sore thumb so i don't think I need to explain where he is. The one with a beast mode- This one was also a bit tricky. I could only find this one in one of the shots. He the one directly to the right side of the mini-con. I came to this because in that shot he seemed to be on all fours. Vector Prime- Your guess is as good as mine. I have no clue. So thats it. Who do you think is who based on the above images?
