Transformers: Cybertron2005

Vector Prime:
Optimus Prime. Get a hold of yourself.

Optimus Prime:
I can't let anyone else get hurt. They trusted me. Am I really worthy of their trust?

Vector Prime:
What are you talking about?

Optimus Prime:
Remember our battle with the Decepticons on Earth? I couldn't protect them from Megatron then and it almost cost them their very sparks.

Vector Prime:
I've heard enough.

[Vector Prime punches Optimus Prime in the face with a tough right hook to Optimus's chin]

Optimus Prime:
Vector Prime!

Vector Prime:
Sheer arrogance. Do you think that your Autobots fight just for you? We all fight because we want to save our homeworld and put an end to Galvatron's evil

Optimus Prime:
Because of me.

Vector Prime:
Because of you we fight as a team.
