Knowing the main writers personally, something by either Murray Gold or Hiroyuki Sawano would be the best fit.
Given the current arc involves Time Travel, and the fact that the 10[sup]th[/sup] Doctor, Donna, and a bunch of The Doctor's foes appeared earlier I can 100% see the Murray Gold, as for Hiroyuki Sawano, Maybe something from his Mecha Anime soundtracks or Attack on Titan, but a definite maybe would be aLIEz
Or a song that Ron Wasserman did called Fight Back, considering how he's done Power Rangers music before, I'd say thiis would a good song to listen to.
Yeah, that went how I expected it to go Anyone else wondering if Great's end would be a good excuse to break out the Stan Bush music? Or would it be better reserved for the next TRUE Convoy\Prime arising like the '86 Film?
The situation definitely calls for that music to be used, so yeah, but every version of The Touch shouldn't be used, I know you were going to suggest that, Optimax, so don't even think about suggesting that song.
I see two enigmas, and that means Great Convoy has or at least HAD the entire collection as part of his plan, let's hope our heroes use everything single one of those to ruin his plan.
And if they work the same way the True Enigma works, then who'd be a part of the 2 Theoretical Combiner Teams? I can honestly see Artillery and Rampage as the Cores of said Combiners, but I dunno about the rest
