(Cog is seen at the space station. He is completely damaged as Optimus Prime communicates with him)

Optimus Prime: Cog. Can you hear me? Are you alright?

Cog: I'm alright. Don't worry about me.

Optimus Prime: I'm sending backup!

(Optimus Prime sends some Autobots to rescue the people at the space station. Unfortunately the station has exploded seconds later. The explosion kills Cog and everyone else)

Sideswipe: Optimus. We got bad news. The station...

Arcee: It exploded...

Sideswipe: Yeah...

Arcee: So this means...

Sideswipe: Unfortunately... Cog is...gone...

Bumblebee: So is everyone in the station...

(Some hours later, the Autobots visit the location where Cog died. Then they put their heads down as Optimus Prime speaks some words to honor their deceased ally)

Optimus Prime: Rest in peace, Cog. Your sacrifice will not be forgotten.

(Unbeknownst to them, Cog survived as he finds himself in a different world)

Cog: Huh? (looks around) I'm still alive... (then he sees humans and demons) Who are those creatures? Are the humans alright? (then he sees familiar figures) Optimus? (to himself) Am I dreaming? (then he sees giant beasts) I just don't get it... I was supposed to die during the explosion in the space station...

(Then he remembers his supposed last moments)

Cog: Was I given a second chance?

(Cog somehow survived the explosion at the space station. What is this place? And why demons, humans, robots and beasts exist in the same world? Did the explosion at the space station cause all of this?)
