Why is Sonic blue? Was Eggman always bald? Is Rouge really natural? Really? You will not find the answers to these questions here. You will, however, find an exhaustive collection of the information you already knew. Characters, locations, items, enemies... if you've seen it in a Sonic game, you'll be able to read about it here.

   All the information in this encyclopedia is as accurate and official as possible. Details are derived from in-game sequences, Japanese instruction manuals, and/or official strategy guides. The goal of this project is to compile a thorough, accurate log of the rapidly expanding Sonic universe. In cases where official information conflicts itself, the inconsistency is noted. There's no fanboy fabrication here. As such, unless otherwise noted, all entries are referred to by their original Japanese names. Finally, please keep in mind that since all of the info comes from the original Japanese sources, translation errors are a frequent issue. Please slap my hand if you catch any errors.

   Entries are coded with these spiffy little squares so you can tell just by glancing what's what:

• = C for Character, profiles of the Sonic universe's cast
• = L for Location, information on key locales
• = I for Item, important objects of relevance
• = E for Eggman, one of the doctor's creations
• = M for Miscellaneous, anything that doesn't fit anywhere else
