What the heck?...

Yup! Optimus made a cameo in HTF and another reason for the crossover! Plus transformers had some pretty brutal moments.

That was more of a reference rather than a cameo.

And what do you refer to "Pretty Brutal Moments"? The movies? The comics?

I meant like Prime, IDW comics, and yes the movies too!

I'm so sorry but...

The "Brutality" in the IDW crap and Prime sucked a lot. They weren't like, well executed. Compared to Happy Tree Friends violence, it sucks.

Marvel Comics had the best violence by far. And not just that, but also had gruesome stuff going on... And also, but not related, the writing was miles better than IDW.
