Antoine's Journal

Antoine's Journal is an object that appears in the Sonic the Hedgehog comic book series and its spin-offs published by Archie Comics. It was a diary kept and updated by Antoine D'Coolette. Antoine's last known entry into the journal during the present day was shortly before he had been sent into a coma after sustaining severe injuries from Metal Sonic v3.5. The journal managed to remain intact 200 years later, where it was discovered by Silver the Hedgehog, which he used to help him hunt down the traitor to the Knothole Freedom Fighters.

History
It is unknown when specifically Antoine began writing in this journal, or whether this is even the first. His last known recording in the journal during the present day (the year 3237) was the day before Elias Acorn and his family fled New Mobotropolis after Ixis Naugus had taken the crown. The following day, Antoine and, what was left of, the Freedom Fighters proceeded to defend the Acorns departure from Doctor Eggman's attack, which would culminate in Antoine being caught in Metal Sonic's self-destruct, leaving him in a coma.

200 years later, the beaten and battered journal was discovered in a library on Onyx Island by Silver the Hedgehog, who at the time was still attempted to hunt down the traitor to the Knothole Freedom Fighters in the past. Examining the worn book, with several words and paragraphs faded out, Silver came to the conclusion that Antoine was the traitor, upon reading many of his entries. Silver was then sent into the past by his master Mammoth Mogul, with the journal, to exterminate who he believed to be the traitor. Of course, he arrived only to discover Antoine comatose, and that he was wrong, again.

Shortly after, Silver was recruited by Harvey Who into the Secret Freedom Fighters. As Silver worked alongside his new teammates to stop an evil Naugus plan, Harvey would figure out the traitor's identity, using both Antoine's present day journal and it's future counterpart that Silver had brought with him to the past, as a base. From this, Harvey was able to figure out that the true "traitor" was Mecha Sally.
