Who is 'The Fallen' in Transformers 2?

 

If you have missed the recent explination behind 'Transformers 2 Revenge of the Fallen' here ya go.

I read an article the other day on another website, whose name escapes me, (If you've seen it let me know I want to go back there) detailing some interesting news about the meaning behind the subtitle for ‘Transformers 2.' Apparently ‘Revenge of the Fallen' is not just referring to Megatron (which I would love to see return), or Jazz (who can burn in hell for all I care) returning and seeking revenge. ‘The Fallen' is actually the name of a robot from transformers lore. Here is the wikipedia definition;

"Although the Fallen's origins are only suggested in his comic book appearance, they would be fully explained in Dorling Kindersley's Transformers: The Ultimate Guide. One of the original thirteen Transformers created by Primus, the robot who would become the Fallen betrayed his creator by siding with Primus's dark twin, the malevolent planet-eater, Unicron. In the final battle between Primus and Unicron, the Fallen fell victim to the same fate as his master, sucked through a black hole into another dimension. However, while Unicron emerged into another universe, the Fallen was not so fortunate, finding himself trapped in the "underspace" between dimensions."

Maybe we even get to see Unicron? I honestly hope not. Galvitron would be sweet though. So all of you who let out a sigh of disgust (including myself) when you heard the title can rest in peace. That is unless this is complete bull shit. The writer of the article stated that he got the info from someone working close to the production. A spot of good news? Only time will tell. Maybe the trailer that they hope to have done by late summer early fall will reveal a little more.
