Edwin Venturi is Derek and Marti's thirteen-year old brother, and Casey and Lizzie's new stepbrother. His father is George Venturi and his stepmother is Nora MacDonald. His birth mother's name is Abby. Edwin is your typical thirteen year-old kid. He enjoys pranking his stepsister Lizzie, though Edwin often teams up with her, than Derek, because they can relate to being the same (or similar) age. He is a devoted follower of video-games (particularly Babe Raider, at first glance is a sexist game), idolizes his older brother Derek, and usually doesn't wash his hands after using the restroom. He is known to be stealthy, and usually does anything Derek asks him to do. He generally attempts to emulate his older brother Derek, perceiving him as cool. Even though trying to be like his brother, the arrival of another kid almost his age (Lizzie) has changed him. He is not as obedient to Derek as before and often betrays him only to beg for mercy later. Edwin has also demonstrated an understanding of higher mathematics well beyond the abilities of an average thirteen-year-old, as in "All Systems No Go" where he shows an understanding of chaos theory. He once had a crush on a "developed" girl.Edwin's longest, and most recent relationship was with a girl named Michelle. She kissed Edwin in the episode "It's Our Party", and Edwin also took her to a Horror Movie Festival. Their relationship ended when Michelle met an archer in her camp over the summer. Edwin usually wasn't hurt when girls left him, but it took a while to get over Michelle, but became best friends with her in school afterwards, and regularly asks for "girl advice" from her.
It is also revealed that he is afraid of mice just as Derek and George are. It is also said that Edwin is relatively weak, lacking muscular endurance. This makes him an easy target for being bullied by Derek and tough kids at school, for he was once bullied by a child at his school named Terence.
