Except there is, Amy debuted in the Shogakukan manga from April 1992. Tails' and Sally's debuts are from November 1992. Though Tails was created not long after/around the same time as Amy since development on Sonic 2 began in December 1991 and Tails was the first thing they came up with for that game. Amy was created for the games but we don't really know when exactly CD started development, probably around the same time since the Sega CD came out in December 1991. The earliest version of Sally technically is from that promotional Sonic 1 comic where she's Ricky but that isn't the proper Sally we know of. Princess Sally was first mentioned in the SatAM pitch bible from February 1992, since SatAM was meant to come out to tie in with Sonic 2. Though her actual debut was in the Archie Sonic miniseries from November
