6. Rewind

(Transformers: More Than Meets The Eye/Transformers: Lost Light, IDW)

What's that? Surprised that there's a transformers comic on this list? You shouldn't be. More Than Meets The Eye (now retitled and renumbered as Lost Light) is one of the best comics of the decade, if not the millennium.

In the series, Rewind was a perpetual observer and documentarian who was in a committed, loving relationship with mnemosurgeon Chromedome. Early in the series, the ship's security officer, Red Alert, discovered the psychotic mass-murderer known as Overlord locked in a room in the ship's basement. Overlord was freed, and he went on a killing spree.

The crew eventually managed to get him into an escape pod, but an obstruction prevented it from closing. Rewind pushed his way inside and cleared the blockage, allowing the rest to blast Overlord away, and simultaneously losing Rewind, as well. In his last moments, Rewind handed Chromedome a drive containing a message edited together out of all the footage the little bot has shot.

At the end of the message was one sentence that utterly destroys me every time:

One more thing, one last thing. Because I don't say it enough: I love you.
