i wanna say blackout or bumblebee

 

according to the Movie Prequel comics it was a Decepticon (Blackout, Barricade and Starscream are seen in the comic during the Mars scene)

 

I always assumed it was Blackout. Definitely can't see it as an Autobot.

 

I could've sworn it was confirmed to be Blackout.

 

I think it's Blackout. But it looks like Megatron at the same time!

 

My guess would be Blackout or Soundwave.

 

Here's a picture of the bot.

 

Soundwave arrived to mars in 2007 the mars hvoer was destroyed in 2003

 

My guess is Blackout, although it just says Transformers, refering to Transformers as a whole, on TFWiki.

EDIT:

Hm..... looks like Bumblebee.

 

Reign of Starscream implied that it was, well, Starscream.

 

It is never confirmed Blackout was the dude who crushed the poor lil robot.

Tom Banachek shows Keller two pictures comparing the aliens in them: One is the alien in MArs, the other is Blackout. Banachek says they believe they are the same exoskeletal type, so that means the one in Mars isnt exactly identical to Blackout.

It seems whoever it was, he was in protoform state.

The movie prequel comics confirms it was a Decepticon, but dont say who.

 

I think it's Barricade  

 

ITS Bumblebee in the Secotr 7 game continuty

but in the mainstream continuty ITS a Decepticon (Barricade, Starscream and Blackout are present when the hover was destroyed in the Comics), they Only used the Autobots protoform model (i can assume they didnt made the Decepticon Protoform model until ROTF)

 

It looks like BB, but I've heard it confirmed to be Starscream.

EDIT: Here we go:

 

Wasn't it supposed to be Starscream? That, or Barricade. I haven't read that comic in forever.

I always assumed it was Blackout who crushed it, since they compare the picture to the rover video. Of course, it could also have been his near-identical cousin Grindor.

 

It's really a toss-up between Blackout and Starscream. Take your pick.

 

Listen to the sound it makes. Sounds like Starscream to me.

 

I always assumed it to be Bumblebee based on the head design.
