Transformers: Dark of the Moon arrives on Blu-ray and DVD, thus completing fans' home video collection of Michael Bay's Transformers trilogy.

Now that the entire series is available for home video movie-marathon satisfaction, we thought we'd follow-up our Transformers: Dark of the Moon character guide with a look back at the entire trilogy and put together a massive compilation to all the Autobots and Decepticons that have been featured in Bay's Transformers universe (for better or worse).

We'll start with the original Transformers (2007), move to the sequel, Transformers: Revenge of the Fallen (2009) and end with third chapter Transformers: Dark of the Moon.

We're leaving no gear unaccounted for, either - from the indistinguishable robot clones to all the silly bots that pop up in each film, to the different versions of popular characters we saw in each installment - we are literally striving to provide you with a "complete" guide to the Transformers movie universe. It's been exhausting "research" putting this all together, so we hope you enjoy.
