* Sally Acorn: Sonic and Sally have a strong, platonic friendship that is often portrayed as romantic in some adaptations, like the "Sonic the Hedgehog" television series. However, the main Sonic games don't typically portray their relationship as romantic.
* Amy Rose: Amy Rose is the character most clearly and consistently depicted as having romantic feelings for Sonic. She is very outspoken about her love for him, often pursuing him relentlessly. Sonic, while he appreciates Amy's affection, is usually shown to be uncomfortable with her advances and doesn't reciprocate her feelings.
It's important to note:
* Official canon: While some Sonic media might hint at romantic possibilities between Sonic and Sally, the official canon of the video games doesn't explicitly confirm a romantic relationship for Sonic with either character.
* Fan interpretation: Many fans have their own interpretations of Sonic's love life, creating stories and fan art that explore different possibilities.
Ultimately, Sonic's feelings are open to interpretation. The focus of the Sonic franchise is more on adventure and action, and the developers haven't clearly defined Sonic's romantic interests.
