Rosie is one of the robots that were created to protect the city streets of the United Kingdom. She was also designed to be very tall.
AppearanceRosie's appearance seems come with the colors of red, white and black. Her arms seem to be a bit long while her legs are a bit shorter and wider. On the center of her chest is a flour-like symbol that has the core inside. She has two red and bright eyes and a red bow tie on her head.
Rosie was designed to be one of the guardians that stayed in the center of the United Kingdom where Vertical Inc is. As it failed at first, the AI started to work a bit later. She was then put on a bunch of tests that see if she could act properly. It didn't work. After a while when hearing about the event that happened with Oradox, they then tried it with someone who was in bad conditions and it worked.
Rosie usually stays in Vertical City where the most advanced stuff is (even though the other cities are advanced). Her actions depend on what somebody does just like some of the other characters throughout the city.
