Sonic the Hedgehog was the primary inspiration behind Surge's cybernetic enhancements, which was why Dr. Starline modified her with powers similar to his and made her believe after dozens of different hypnotic sessions that she hated Sonic with all of her heart and wanted to destroy him. However, once she discovered who she was, she gained a genuine hatred for Sonic, finding him responsible by proxy for her existence as a cyborg due to Sonic's refusal to take the lives of his enemies. Utterly convinced that she is Sonic's superior, Surge wants nothing more than to crush Sonic and prove her superiority to him, and will become furious at the prospect of appearing weaker than him. After learning the truth about her origins as a cyborg, however, Surge now seeks to destroy Sonic, not because of Starline's hypnosis, but rather because she does not believe he deserves a future if she cannot know her past.
