The Insectitrain Queen explains Thomas isn't the only Train Prime

Here's when Empress Krone explains to Thomas that he isn't the only Train Prime in The Age of Empress Krone.

Thomas: Listen Krone, your words don't scare me. Because I'm wise enough to listen to villains talk.

Empress Krone: Of course, of course, but you know, do you think your the only Train Prime?

Thomas: What are you talking about? How do you know about Primes?

Empress Krone: My mentor told me everything about Primes, even the "true" Train Prime?

Thomas: The "true" Train Prime?

Empress Krone: Thomas, Thomas, Thomas, if one is the understand all the Primes, one must even know all the Train Primes, even counting the Ultratron, if you wish to know all the Primes, you have to know everyone of them. But be careful, Thomas. He or she is after you, and he or she has a price on your head. [smiles]

Thomas: What did you just say?

Empress Krone: You heard me.

[Thomas activates his lightsaber and points it at her]

Thomas: Tell me who he or she is?!

Empress Krone: Im afraid I don't know him or her. But listen to me, he or she won't stop till he or she have you. Hence is why during the TBC incident, he or she hired that scary bounty hunter to find you, and bring you to him or her. But unfortuently failed.

Thomas: [points his saber closer]

Empress Krone: Are you gonna kill me so you can find him or her?

Thomas: I would certainly love to!

Empress Krone: I know you would. I can feel your anger, it gives you focus, and makes you stronger.

Thomas: [deactivates his lightsaber] I'm gonna tell the others about this.

Empress Krone: Of course, but your not sure if they believe you?

Thomas: I will discover the truth of this.

Empress Krone: You have great wisdom, Thomas. Find out who this Prime is, so you can protect your planet, your friends, and family.
