In the story arc "City at War", Michelangelo instantly bonds with Casey Jones' adopted daughter Shadow, who nicknames him "Rooish". In the second volume, the Turtles decide to try to live apart from one another. Michelangelo, the social creature that he is, moves in with April and Casey so that he can be close to Shadow. Throughout the first two volumes, Michelangelo seemed to act as peacemaker of the team. These stories also laid the foundations which demonstrated his closeness with his older brother Donatello, their laid-back natures separating them from the more contentious Leonardo and Raphael.
