Starscream never shuts up, it's a common fact that everyone knows, but somehow his greatest talent is keeping his own secrets, even when he's rambling about nothing in particular.
Many think that his high-pitched and mildly screechy voice is annoying, but you actually like it.
There's so much passion and emotion in every word, and even more information able to be learned through his movements and expressions.
It almost seems as though everything Starscream does is with the utmost theatrics and the most drama he can fit in without it feeling forced.
He's just a very extra 'Con, and you love that about him. But, if you're being completely honest, you're not focusing on his words. You're focusing on the sound of his vocaliser in your audials, the slight crack in his voice box that he makes when he gets particularly loud, the staticky sounds he makes when he gets particularly loud.
One might call it a bit grating, but its a pleasant kind of grating. A comforting kind of grating, because you know full well that Starscream can talk the world away.
No matter how upset or horrible the universe seems, Starscream never fails to make the rest of the world fall away.
Honestly, his vocaliser is comforting, and if you could, you'd fall asleep to it every night.
"-And then Megatron refused to just kill Optimus Prime, because apparently it's not 'sporting' to kick an enemy while they're down and he wants to fight Optimus at his full power!" He flails his arms wildly as he spaces around the Hab-Suite. "And then when I told him that we're Decepticons - because we are, he dented my wing! Look!"
Starscream pauses, glancing at you and visibly sagging when he sees the distant look in your optics.
"You're not even listening to me!" Starscream screeches, his vocaliser crackling a bit as his wings flare up and bristle in irritation.
