You, Elita-1, B-127, D-16, and Orion encountered Alpha Trion and he told you guys how Sentinel wasn't the Prime that he truly is. Soon, Sentinel and Airachnid bombed the cave that you guys were in and his men barged in. Alpha Trion told you to flee, so you did.

Orion: "We need to hurry!"

D-16: "I still think we have better odds fighting than out running them!"

Elita-1: "Wait, we have Cogs! We can transform now!"

Orion: "That's right! Everyone ready?"

Elita-1: "I was BORN ready!"
