Both series share some key themes: supernatural abilities determined by one's deepest wishes, the concept of soul, similar "food chain" theme of superhuman creatures and a character who can stop time.
In both, characters have powers determined by their wish/fighting spirit. Both have creatures stronger than human and character that can stop time. Both anime are violent in tehir own way. Mahou Shoujo Madoka Magica is more psychological, JoJo's Bizarre Adventure is more horror.
