'Transformers 5: The Last Knight' spoilers, plot news: Big bad revealed, 'loneliest dog' nabs a role

A familiar face returns in "Transformers 5: The Last Knight." Director Michael Bay teased on his Instagram account the return of Megatron, who was the antagonist in all four films.
This was the surprise for the last day of May that the cryptic message was pertaining to in the teaser trailer. Since development hasn't started yet, it's understandable that what was shown was not new footage but plot revelations.
Fans instead got to learn who will be the big bad in "Transformers 5." Megatron was already defeated by Optimus in the third film "Dark of the Moon." However, it appears he will be resurrected in the upcoming movie, which wasn't much of a shocker.
According to GameRadar, Megatron could be a vital element in Hasbro's plan to establish a cinematic universe for "Transformers," which is why he is part of "Transformers 5: The Last Knight" once again.The site says a Megatron solo movie might even happen in the future.
"Transformers 5: The Last Knight" will star Mark Wahlberg once again as inventor and mechanic Cade Yeager. He will be joined by Nickelodeon starlet Isabel Moner as well as comedian Jerrod Carmichael. Josh Duhamel will also reprise his role as Lieutenant Colonel William Lennox. He played the character in the first three films. His return is also believed to be an effort to set the stage for the "Transformers" cinematic universe.
The latest addition to the "Transformers 5" cast is a cute pooch dubbed as "Britain's loneliest dog." Bay announced the inclusion of the Staffordshire bull terrier cross named Freya on his Twitter page. The adorable pooch has been in a shelter her whole life, but this ends soon because she is getting a big screen debut and a new home. "Freya has epilepsy and has been in a shelter her whole 6 year life. We are also going to find her a home," Bay tweeted. If not she will come to my house. Welcome to the cast Freya," the filmmaker added.
There is no official word as yet. Disney decision on season 4 coming soon. Officially, season 3 ends with 3 wonderful episodes in January.

As much as I love Shawn Hunter, having created his character and everything, you have to remember that he was wrong a lot.
