Sounds good putting it all together, at the end of the day, you have to remember this is a Bay movie, which means its a Hollywood blockbuster and in these situations, you have to always use the KISS mindset. Keep It Simple Stupid. Whichmeans, the Fallen is not a new character that no one really knows about. What happend in
TF1? Megatron is defeated and falls into the ocean.
TF2? Revenge of the Fallen. The Fallen is Megatron and the havoc he creates. Think of it like Star Wars. It went New Hope, then the middle movie Empire Strikes Back, then in the third, the good guys get their win. So
TF2 Megatron will reign supreme and in TF3, Prime and co will defeat all and end the war.
No time to introduce a character called the Fallen. 90% of the normal fans (e.g., the ones not visiting boards like this) have no idea that there was a Fallen character or anything like that, so you have to really keep it simple when it comes to these types of Hollywood movies.
