Optimus and Unicron in “Unfinished Business”

Optimus

I humbly request your ear, Lord Unicron.

Unicron

And what would a Prime be so compelled to say to me?

Optimus

I make this appeal not for myself, but for this planet which you constitute – and the beings that inhabit it. Humankind relies upon you; for life, sustenance. Your resurrection will only result in the destruction of a species which evolved from the seeds of your very greatness.

Unicron

So this humankind of whom you speak… you consider them my progeny?

Optimus

Indeed.

Unicron

PARASITES! They, too, shall know my wrathful hand – once I am finished with you!
