    Sonic 197: "Consequences" - Shortly after the end of 196 (a day after the main portion of the story).

* Sonic 191: "Invaders From Beyond"
--Note: This is the pre-adaptation for "Sonic Chronicles: The Dark Brotherhood". As it makes no reference to non-SEGA-Sonic elements of Archie continuity, it may be non-continuity. If it is continuity, placement is hard - there is at least one green Emerald in the world (and Knuckles has it), Tails has had a blue plane called the Tornado, and Sonic is said to be out journeying (alone); at no point in the comic have all of these been true at once.

* Off Panel: Sonic Universe 1

* Sonic 193: "Sonic Unleashed!"
-- Note: Sonic Unleashed Pre-Adaptation. In this story, Robotnik had a Space Armada before Super Sonic trashed it, which doesn't fit with the time period following Enerjak Reborn. Likely non-continuity.

* Sonic 197: "Sonic and the Black Knight: Knight Time"
-- Note: "Sonic and the Black Knight" Pre-adaptation. No evidence regarding whether this is Sonic Prime continuity or when it might take place.

* Showdown With Eggman
    Sonic 198: "Phoenix-Down!"
    Universe 2: "Time & Again" - The night after "Phoenix-Down".
    Sonic 199: "Knocking on Eggman's Door" & Sonic Universe 3: "Old Soldiers" (pages 1-5) - The morning after "Phoenix-Down".
    Sonic 200: "Turn About is Fair Play" - immediately following "Eggman's Door".

* Off Panel: Sonic Universe 2

* Sonic Universe 3:
    "Old Soldiers" (pages 6+) - several hours after the end of the battle with Robotnik.
    Off Panel

* Iron Queen Invasion     Sonic 201: "Change in Management" & "Devotion" - A couple days after Sonic 200. Stories simultaneous.
    Sonic 202: "Dangerous Territory" - Immediately following Sonic 201.
    Sonic 202: "A Lonely Girl's Story" - shortly after "Dangerous Territory"

* Sonic Universe 4:
    "The Ultimate Lifeform" (except final page)- Not too long after "Old Soldiers", as they are carrying out the mission received there; however still long enough after for Omega and Shadow to have sparred several times.
