I've never cried over Transformers, but I did get sad when Dinobot died in BW and when Ironhide died in DOTM.

 

I (at least almost) cried over the deaths of BW Dinobot, BW Transmutate, DOTM Que, and Cybertron Vector Prime (especially Vector Prime).

 

I was definitely upset by Vector Prime dying, I don't think I cried though. I didn't cry when Dinobot died, I was too busy shouting "WHAT?!?! NOOOO!!!" at the T.V.

 

Optimus's death in Transformers: The Movie and Dinobot's in BW always brings a tear to my eye.

 

I'm a heartless wretch, so I never cried for anyone in Transformers.

Though I was severely saddned in WheeljaQ's death in DOTM because the dude was really naive ["Bee, I think they are going to kill us!"] and somewhat the only "innocent" member of the Autobot Team, it was sad seeing such a non-fighting figure get killed, it really brought home the pain and suffering a War causes.

I was sad at ROTF-Jetfire's death too because he was a charismatic character, seeing him die so soon was sad [the words he says when he dies don't help much either: "In my whole life, I never did anything truly worth of being remembered. Take my parts Optimus, fullfy your destinity!"].

 

Optimus Prime in Transformers: The Movie, Dinobot in Code of Hero, Starscream in Cramp, Prowl in Endgame Part 2.

 

I admit I shed a tear during that scene as well. 

 

Dinobot, most definitely. TFA Prowl got a choke out of me.

 

Dinobot, most definitely. It gets me every time. I remember the first time I saw Code of Hero, the ending left me stunned. I just sat there in front of the TV blubbling my eyes out for a good 5 to 10 minutes after it ended. And this was when I was 15, mind you. I had no idea he was going to die.

TF:TM Optimus Prime. I've gotten misty eyed a couple of times watching this, but I've watched it so much I think I've gotten past that point.

DOTM Quejack, I mean, like OB said, he was just so niave and helpless.It was sad to see him being so mercilessly executed. Although, the music probably was a major factor in me tearing up because Quejack wasn't really characterized all that much.

 

I bawled when I watched my brother many years ago intentionally, slowly, and mercilessly snap the stacks off my Optimus Prime toy. Still a little bitter.

 

I didn't cry but was shocked when Prime died in the 86 movie and was traumatized after they killed the Autobots in the Shuttle, seing how Megatron finished off Ironhide and how Scavenger killed Prowl I was like WTF?, and later on seeing Wheeljack and Windcharger gunned down.

 

MEGAN FOX'S ACTING MADE ME CRY! HAHO! Moving on.

Ironhide's death in DOTM made a verbal "Shit!" come out of me...

Uhh ... Yeah. There we go.

 

I cried when Optimus died in 1986[TF the Movie]  

I also had a weep over Ironhide in DOTM  

Vector Prime-in Cybertron 

 

Ive never actually cried when characters have died ive felt extremely saddened when some characters have died.
I didn't feel sad but i felt bad for some of the Cons in the movie.

 

I cried the first time I saw prime die in the 86 movie I was only 5 though

 

I didn't cry but my heart just sank when I saw the 86 movie when Prime and the others died.

 

Cried when movie Devastator died because he was so wasted

 

Bumblebee

I cried in Dark of the Moon when Soundwave was about to execute Bumblebee. It was such an emotional scene! And to make matters worse, I had taken my girlfriend to see it with me and she saw me cry. Hehe, oh well! 

 

I get a bit angry when Prowl gets killed in TF:TM but thats only ecause Prowl reminds me of myself. I only cry when Dinobot dies

 

Transformers #25 when Megs gets taken down made me go wow!
Transformers comic #76 when Prime is barely hangin' on, also was powerful.
Vector Prime's death was ballsy.
Op in TF the Movie had the biggest emotional impact.
