The head of the Machination is a Transformer, but as explained in Spotlight: Ultra Magnus, he works through several layers of lackeys, with only the top level employees (I am assuming Dante and maybe one or two others) knowing who they really work for.
One of the people is one of the scientists working on the project. Coming in at night. He has the proper security clearance. Guards probably won't notice until they see the strange behaviour on the TV screen. Even then, they'd probably just leave them alone and watch.Again, remember, most Machination employees don't realise they work for a Transformer.
The robots right at the beginning are the people that Sunstreaker either led, or worked with, before he was transferred to Earth. That one's right at the bottom of the page.![]()
