Been reading through this series post-dark cybertron a few times recently because I didn't feel I gave it the chance it really deserved; my initial reading of it was "extra understanding of what happens in MTMTE's universe". So giving it another chance, it's been incredible.
And for reasons I don't feel I can adequately put into words...
This is one of the most powerful lines in Transformers history to me.
It sends chills down my spine. Galvatron goes on this long speech about how everyone has to count on him to combat the bigger threat coming; that there's no way they can hope to stand against it without him, and... and then Prime delivers
that.
It's such a brilliant juxtaposition. It's such a brilliant use of the medium and of panel space. It's a fantastic resolution and an amazing subversion of the heroes-and-bad-guys-team-up-to-defeat-bigger-bad-guys trope. And in certain respects, it's politically relevant.
I'm just rambling on here but I just couldn't not comment on it. It's chilling, it's well done, it hints at Optimus' coming character and it's a great way to end the comic with a trope subversion. I love it.
And... one more thing. I think they seeded a contrast to this quite some time ago.
