It is noticeable for being the first Sonic media to include the concept of an ancient advanced echidna civilization that became used later on in more major media.
Sonic Adventures provides examples of:
- Advanced Ancient Humans: According to Sonic, echidnas once had a very advanced civilization and were the first intelligent species.
- Character in the Logo: The logo of the comic has Sonic winking above the "i" in his name.
- Gratuitous English: The comic is in French, but the title Sonic Adventures is in English. This makes sense because the French word for "adventure" is "aventure", which is similar to the English word.
