Starscream forms an alliance with MECH

This is how Starscream forms an alliance with the Changelings goes in Operation: Bumblebee Part 1.

[We see the Changelings working on something]

Starscream: [laughs] You are the ones that turned poor Breakdown into a pitful science experiment? Didn't learn much from the expierment, did you?

[The Changelings charge their magic, ready for a fight]

Queen Chrysalis: Enough to know where the soft spots are, Decepticon.

Starscream: Oh please, I no longer affiliated with that entity. Besides, if I were to avenge the big lug, you would be screaming for mercy by now.

Queen Chrysalis: Why are you here?

Starscream: To propose an alliance. You see we have much more in common than you think. And I am not merely referring to our battle scars.

Queen Chrysalis: What could I possibly gain from such an arrangement?

Starscream: Insider knowledge.

[Queen Chrysalis gives the Changelings the signal not fire and they back away]

Starscream: Wise choice. Now, a T-Cog isn't technology. It is biology. Which means it will reject any power source... except Energon.

Queen Chrysalis: Go on.

Starscream: Energon is the fuel, the ammunition, and the lifeblood of all Cybertronians. Whatever their affiliation. You and I both want it. And currently, I lack the means of locating it. But once I supply you with the… [scratches his finger] Particulars of its chemical makeup.

[Starscream douses some into the robot body on the wall]

Starscream: We can utilize your considerable resources to devise the means of detecting new deposits for us to share.

Queen Chrysalis: If the supply meets the Changeling's rather significant demand.

Starscream: Ahhh, intending to build an army are you?

[He turns to her]

Starscream: I am no stranger to ambition.
