Moments before the humans arrived, the Autobots both activated their holoforms. ((Yes, Autobots can create holographic humans to look like drivers. Arcee does it for her motorcycle form)). Optimus had one that looked like a middle-aged man with a scruffy beard and blue baseball cap. It had sunglasses to cover its eyes. It appeared to be wearing a pair of blue jeans and a red jacket. Ratchet's holoform appeared to be a grizzly old-looking paramedic. It too had sunglasses.

"Greetings, I'd tell you where we were if I knew." The holoform said, opening the door and stepping out. One notable thing about cybertronian holograms were that they could be tangible if need be.
