What would you like as a post-credit scene? Mine would be: (Autobot *lab* with Prime, Rachet comes in) Ratchet: Optimus, may I have a moment? It seems the humans have made an interesting discovery. OP: What is it Ratchet? R: (Hologram pops out) At an archaeological site, the humans have dug up this fossil claw of a Deinonychus antirrhopus, also know as the Velociraptor. What's interesting is that the fossil is dated at around 4 million years ago, and the species was thought to have died out 100 million years ago on this planet. OP: That is very interesting, although I have the feeling that's not why you brought it to my attention. R: No. Analysis of the fossil shows faint Energon markings. Not just that, they seem to be an advance form of refined Energon, more efficient than the ones we use. OP: But how can this be? This technology is beyond our capabilities, but it seems it has existed in the past.... R: I don't know Optimus, but it looks like the Primes were not the first Cybertronians to visit Earth.... (scene focuses in on the image of the fossil and then cuts to black) (cue Beast Wars theme) ----- Sorry if it sucks, I'm not really good at writing fanfic, just thought this would be a really interesting scene.
