Dan Aykroyd loved Chevy as a friend but not as a person, he thought Chevy was too cocky and arrogant for his own good. He thought that Chevy's attitude needed to be adjusted and that's when he decided to invite Chevy over for the night, that night as he and Chevy were talking to each-other, Dan reached over and hugged him...Chevy jolted back and felt a sensation go through his body as he slowly transformed into an identical version of Dan and he screamed as it happened, a couple of hours later Dan conditioned him and within seconds Chevy was just like him, and now Chevy was cursed to become a Were-Aykroyd whenever he didn't listen to anyone or acted out, the Aykroyd side would always kick in and take him and make him act nicer.
