Optimus Prime ever destroyed anyone?

I tried using the search feature but it doesn't seem to be working no matter what keyword I use. 
Anyways, I'm kinda new to the entire Transformers fandom. I've seen some of the series, read some of the comics, this and that~ One thing I've noticed so far is that whenever I see Optimus Prime in some kind of final fight with Megatron, something else ends up killing him instead. :O Out of curiosity has Optimus Prime ever destroyed/killed any characters from the series or is he reeeeeally too much of a good-bot?
