You were a Predecon, taking on a more. . .dated creature. An Indoraptor. A large Dinobot with no intention of siding with anyone at the moment.

Optimus was scouting an area for recon, having gotten a signal from a Decepticon from this exact area. He spotted you, and quickly hid behind a mountain nearby. He poked his head out from his hiding spot, trying to get a better look at you, and what you were doing.
