Chronos the Cat's
Myth and History
* Long ago, an ancient race of giants is said to have lived.
["The Void".]
* Long ago, the city of Maga was built.
["Sonic and the Secret Scrolls]
1543 - Ironlock Prison built.
["Sonic Boom"]
3134 - Ironlock Prison abandoned.
["Sonic Boom" - 100 years ago. Of course, chances are the writers
had no idea what year it was on Mobius when this episode was written - 1591
years is a long time for a prison to be in use!]
The Great War:
* Mobotropolis goes to War.
["Blast to the Past". The Kingdom of Acorn's adversary in this war
is not revealed in the show.]
* Julian and his nephew Snivley join the forces of Mobotropolis.
Julian becomes Minster of War, gaining the title "Warlord".
["Blast to the Past" & "The Void"]
* Doctor Charles Hedgehog is knighted, becoming Sir Charles.
[In some episodes he was referred to as "Dr. Hedgehog", in others
as "Sir Charles".]
3229 - Sonic Hedgehog and Princess Sally Alicia Acorn are born.
["Blast to the Past". Sonic and Sally were 5 in 3224. Sally's
middle name was also revealed in that episode, though her last name being
"Acorn" was never specifically said in any episode.]
* Sir Charles builds the Roboticizer to prolong life, but it strips
away a person's free will. He abandons the project, but the War Ministry
takes the files.
["Blast to the Past". There is no indication how long ago this was,
but it was likely not too long before 3234.]
* Warlord Julian has many robots built to win the war and protect
Mobotropolis. The robots in the city are known as "Peace Bots" and only
have stun weapons.
["Blast to the Past". Julian and Snivley planned to retrofit the
PeaceBots with laser-weapons.]
The Coup & Beyond
3224:* The War is won, thanks in no small part to Warlord Julian.
["Blast to the Past". The King thanks Julian for winning the war.
Is implied that this happened quite recently.]
* Julian submits plans to dismantle the military, but he and
Snivley secretly begin preparing to take control of Mobotropolis.
["Blast to the Past".]
* Timeline Two: Past portions of "Blast to the Past" Part One, and the beginning of Part Two (probably up to the point where Sonic and Sally are captured in Part Two)
* Shortly after taking control of the Palace, Robotnik traps Naugus
in the Void.
["The Void". Naugus calls Julian "Robotnik", and Snivley calls him
"Sir", so it must be after the Coup begins.]
* Timeline Two: Portions of "Blast to the Past" Part Two (from the earlier break-away-point to Sonic and Sally's rescue of Sabina).
* Both Timelines: Robotnik exiles King Acorn to the Void.
["Blast to the Past". Robotnik tells the King to say hello to
Naugus, implying that Naugus is already trapped in the Void, and placing
this scene after the flashback in "the Void".]
* Timeline Two: Remaining Past portions of "Blast to the Past".
3225 - Tails is born.
[In "Drood Henge", set in 3235, Tails is 10.]
* Timeline One: Rosey is captured by Robotnik's forces and roboticized.
["Blast to the Past" Part Two. Presumably sometime between 3224 and
3230, as Sally said Rosey was captured when they were kids.]
* Robotnik captures Lupe's father and most of the Wolf Pack. The
remaining Wolves flee from their ancestral homeland, but Lupe is scarred in
the process. By the time of "Cry of the Wolf", only 10 Wolves remain.
["Cry of the Wolf"]
3229 - Sonic goes on solo missions without permission.
["Drood Henge". Sonic said he was 10 at the time.]
Season One

[Robotnik is returning to Mobius at the beginning of "Heads or
Tails".]
"Heads or Tails" - Robotnik returns from his trip.

"Sub Sonic"
[Occurs prior to the acquisition of the "Subter File" in "Sonic
Boom."]
"Sonic Boom"
"Ultra Sonic"
"Sonic & Sally"
"Super Sonic"
"Sonic Racer"
"Harmonic Sonic"
"Hooked on Sonics"
"Sonic's Nightmare"
"Warp Sonic"
"Sonic Past Cool"
"Sonic & the Secret Scrolls"

Season Finale.]
* Robotnik is discovered to be alive.
["Game Guy" and other Season Two episodes.]
Season Two
3235* The Freedom Fighters recruit Dulcy the Dragon.
["Game Guy" and other Season Two episodes.]
"Game Guy"
"Sonic Conversion"
"Blast to the Past" (One and Two)
[Note: Sally's comment of not having seen her father in years
makes this prior to "the Void", despite Nicole speaking to Sonic in
"plain English". Luckily for the sake of the timeline, this "plain English"
is not the slang-filled kind she learned in "the Void".]
"Fed Up with Antoine" / "Ghost Busted"
[Note: In "Fed Up", Antoine decides he is a "King Fu" master. He
refers to it again in "Ghost Busted", adding a bit of continuity between
the two episodes.]
"Dulcy"
[Note: It is implied in this episode that this is Robotnik's first
encounter with Dulcy.]
"The Void"
[Note: In this episode, the Freedom Fighters learn of Doomsday for
the first time.]
"Ro-Becca"
[Note: Antoine's house is the same here as at the beginning of "the Odd Couple". Considering the damage it suffered in "The Odd Couple", it
seems unlikely it was repaired back to the same it was before - thus,
"Ro-Becca" must come first.]
* Rotor manages to turn off Ro-Becca again, and dismantles her.
[Rotor had planned to do this during "Ro-Becca", but didn't get
around to it before the end of the episode. However, she is never seen
again.]
"The Odd Couple"
[Note: Takes place during winter time. For placement relative to
"Ro-Becca", see the note on that episode.]
* Sonic encounters the Doomsday Test Pod.
[Sonic mentioned having seen what it can do before in "Cry of the
Wolf".]
"Cry of the Wolf"
"Drood Henge"
[Notes: Sally will be 18 in two years, making her 16 in this episode. Tails is 10.
Chronological trivia: In this ep, Snively picks up the nickname for Robotnik "Big Round Guy" from Sonic.]
"Spyhog"
[Notes: In this episode, Uncle Chuck begins using a Tech-Bot disguise.]
"No Brainer"
[After "Spyhog" - Uncle Chuck and Sally use Tech-Bot disguises.]
"The Doomsday Project"
[Season Finale]
The Future
* Snivley takes control of Robotropolis, and he and his ally prepare to
face the Freedom Fighters.
["The Doomsday Project" revealed Snivley's plans. Ben Hurst meant
for Snivley's ally to be Naugus, but this is not revealed in the episode.]
3237 - Sally turns 18, and comes of age.
[Two years after "Drood Henge".]
