Blood for the Baron!

Tony: Hi, do you remember me?
Buzzsaw: Tony Stark. I almost don't recognize you, you have become an Iron Man.
Tony: It's all due to you, and I intend to "thank" you.

Skywarp: Oooh, so slow. You can't catch me.
Sideswipe: You can't warp forever, Skywarp.
Skywarp: Do you want to bet?

Brawn: Lt m g, mnk-fc!
Hulk: HULK SMASH!
Sunstreaker: You are not going to "smash" me, monster. You defeated Brawn, but now you'll face the best.
Hulk: Hulk destroy yellow tin man.
Sunstreaker: Come and try it.

Cliffjumper: Facing me without weapons, Laserbeak? I expected a challenge.
Laserbeak: I can tear you apart with my beak and my talons, while my Booster X10 automatic weapon system gets rid of other Autobot.
Hound: Argh!

Carnage: Come here, little guy! I have always wanted to know how looked robot guts.
Bumblebee: You're a sadistic monster! Is that what happens to all people posessed by symbiotes?
Carnage: You say like your friend Spider-Man? Who knows? I was twisted before finding the symbiote! HAHAHAHAHA!

Reflector: Argh!
Prowl: Your camera mode could be good for reconaissance, but lets you with a glass chest, a very evident weak point.

Jazz: Do you expect me to talk?
Soundwave: Negative. I do not require any information right now.
Jazz: You don't see much movies, do you?

Starscream: I have Optimus and Nemesis in my sights. One single shot and I'll get rid of them both!
Cap: How evil! You don't have loyalties even for your own? I'll stop you!
Captain America remembers what Wheeljack said about "extra defense" and...

...when he checks his MegaMorph's back, Cap finds a giant replica of his lost shield! Cap feels like he had recovered his right arm, but he has no time to think about it.
Cap: Beware, Optimus!
The null-ray shot bounces on the shield and returns to Starscream.
Starscream: Argh!

Nemesis: Traitor! I'm going to kill you right now!
Starscream: Forgive me, Nemesis Prime! I only wanted to terminate Optimus Prime!
Nemesis: Why are you running then?
