"Transformers: Animated" The Elite Guard (TV Episode 2008) - Townsend Coleman as Sentinel Prime

Sentinel Prime : As you know I've scanned some typical earth vehicles, sir, so we won't attract attention to ourselves.

Ultra Magnus : Good work Sentinel Prime, transform!

[they transforms into a heavy transporter and odd looking truck]

Bumblebee : Yeah, who's gonna notice that...
Sentinel Prime : I think you've done enough, Optimus. I'll make sure you're tried for high treason for destroying the AllSpark. Now come with me.

Optimus Prime : No!

Sentinel Prime : That wasn't a request. That's a direct order, Optimus!

Optimus Prime : It's Optimus Prime! I may be an Elite Guard washout and a glitch-detail flunky, but the last time I checked, you and I still had equal rank. So, Sentinel Prime, take your order and your condescending attitude, and stick it in your hard drive! You're on my turf now!
Ultra Magnus : Definitely appears to be a fragment of the AllSpark. Apparently, your story about dispersing it may not be so far-fetched after all.

Sentinel Prime : But, sir, you can't honestly believe that. He's a lying, insubordinate crankshaft.

Ultra Magnus : He may be a little rough around the edges, but in the heat of battle, Optimus Prime exhibited the qualities of a true leader: Strategic thinking, determination, and above all, loyalty. Something you could stand to learn a thing or two about, Sentinel Prime.
