Corrected entry: When Sentinel Prime is revived he is immediately speaking English. I know that the Transformers can learn a language quickly via the Internet, but he was just revived and in under a second is practically fluent.

Correction: Sentinal Prime was headed to Earth when he crashed on the moon. He certainly learned the languages before he disembarked. Most likely via intercepted radio transmissions.
