Knuckles' first three part miniseries "Sonic's Friendly Nemesis Knuckles" was released in 1996. His second miniseries was published in 1997, "Knuckles: The Dark Legion" and after three issues was continued into "Knuckles the Echidna" which began starting its numbering from issue 4. Archie has essentially 'retconned' "Sonic's Friendly Nemesis" as being "Knuckles the Echidna" 1 through 3. This was also done with the "Sonic Vs Knuckles: Battle Royal" one-shot which they 'retconned' into being "Sonic Super Special" #1. "Knuckles Chaotix" is a one shot that ties directly into the ongoing series.
