This is mostly off the top of my head, so it's far from exhaustive, but...

He's a bit chatty in "Thief in the Night".

Not very many at all... I want to say that the brief scene with him and Alpha Trion in "Forever is a Long Time Coming" is the closest you'll get.

He doesn't talk like a caveman in his lines in "Fight or Flee" (though he's still not very bright).
Arjun_M wrote:Defensor in action, with all five machines together.
Pretty much all of his appearances, "BOT", "Carnage in C-Minor", "The Burden Hardest to Bear", "The Return of Optimus Prime 1". He's missing an arm in "The Ultimate Weapon", but that's a good ep for general Protectobot action.
Arjun_M wrote:Blitzwing...other than Triple Takeover
He gets some decent air time in "Cosmic Rust" and "Prime Target", though his shining eps are "Five Faces of Darkness" 3 & 5 (especially part 5).
Arjun_M wrote:Astrotrain in all three alt-modes...other than Triple Takeover
I'm actually having a hard time thinking of times where he uses his train mode... I think he does for a brief moment in the original movie.
Arjun_M wrote:Blades in action...attacking
I don't think there are any, sadly. Still waiting on a full-blown badass portrayal of Blades in canon, though his small part in Megatron Origins isn't bad. (I have seen an awesome fan comic page with him doin' the rotor-chucks, though.)

Blanking on this one, though I know there's gotta be some.

Aren't they always comical? *ducks*
Arjun_M wrote:The Combat Deck in action
Blanking on this one, too... though it was probably in first season episodes if it was in any.
