Bumblebee and Optimus both like westerns. I like to think Bumblebee and Raff got Optimus into them too. How cute would that be seeing the three of them watching them together?

Ratchet I think would like medical dramas.

While Shockwave would be into documentaries.

Bulkhead we know likes to watch monster truck shows or demolishen derbies with Miko.

Arcee would probably like action shows like the Arrowverse or Agents of Shield.

Smokescreen I think would like sports. Or Superhero shows.

Megatron I can see getting into wrestling it might make him think of his gladiator days. But I think he also has a secret liking of the My Little Pony franchise. How funny would that be a big strong warlord like Megatron liking a cute show like that.

(I actually don't know much about that show myself having only played one computer game of it a long time ago and the only other thing I watched from it was the Death Battle between Starscream and Rainbow Dash. But since that one promo on the hub said the theme was Megatron's favorite song I'm going out on a limb and calling it his guilty pleasure. XD)

Soundwave would probably be in to musicals. And just watch random stuff to get recodings. (Kind of like how Bumblebee did on Cyberverse.)

Dreadwing probably would have liked military shows.

And I think Ultra Magnus would probably also be into military or cop shows. I also imagine him watching the news a lot.

We know Knock Out likes horror shows. I think he would also like racing and car shows as well as cartoons or comedies. (I can totally see KO chilling and having a good laugh over them.) I can also picture him watching some medical dramas.

I can also see Breakdown liking horror shows and probably wrestling. (I can definitely see him watching the horror shows with Knock Out.)

Starscream I think would like anime, comedies or cartoons. But it would also be funny to see him get into a drama or soap opera or something.

Arachnid would probably like soap operas but would be taking notes on how to torture people. XD.

And I can see Predaking watching the discovery channel.

And the Vehicons would have different taste probably watching a lot of game shows or Food Network or something.

Hope you all enjoyed theses Headcanons there will be more to came. I just wanted to write something and couldn't think of anything for my current stories at the moment but I will try to update them soon.
