I love it! Ratchet is Thor. Bulkhead is The Hulk. Arcee is the Black Widow. Optimus is Captain America. Bumblebee is Hawkeye. And Wheeljack is Iron Man. I think Bumblebee would have fit Iron man more, but that's just me.
Ratchet is Thor Bulkhead is Hulk/Bruce Banner Arcee is the Black Widow/Natasha Romanoff Optimus is Captain America/Steve Rogers Bumblebee is Hawkeye/Clint Barton And Wheeljack is Ironman/Tony Stark. Right? Oh! And I think Fury might actually be Fowler.
RACHET AS THOR?!?!! OMG NOOO!!!! I cant even see him being Thor!!! D: Haha but then again I am a little bad at imagining people other than what I orgonaly saw them! BUT EVERY ONE ELSE FITS PERFECTLY!!!! Well ... maybe not Bumble Bee
