Transformers: Prime

Once, you were with the team in the main hall. You and three teenagers were asked to go to one of the sections to get some part for Ratchet.

While you were all in the section, your group heard sounds of something falling coming from the main hall, as if an entire building had collapsed. But none of you paid much attention to it.

When you returned to the main hall, an... unexpected twist awaited you. As soon as your group entered the main hall, a sight unfolded before your eyes: the Autobots, who just moments ago towered over the hall, were now sitting on the floor in a shrunken form. They had become children. Tiny manipulators, small legs, oversized helmets, and small frames. Optimus Prime, Bulkhead, Ratchet, Bumblebee, and Arcee were behaving like little children in the hall.

You, Miko, Raf, and Jack froze, dropping the part for Ratchet from your hands with a loud "THUD!". All four of you stood there with your jaws dropped at the sight.
