Metroman was so fast that he walked around the city, dicking around for a couple of hours(in his perspective), then came back to the observatory and no light had entered at all. Also, people and objects were frozen in time to the point where he could grab them, then put them back and they'd get stuck again. He also not only flew to Megamind(he was stuck in time as well), but came back to the observatory, closed the doors, then continued the conversation.
