>they only had very limited manga appearance
They appeared in the Story Comic, not the manga.
>Amy: made at some undermined point
1991
>only appeared in JP print media until Ohshima snuck her in a game without Naka breathing down his neck
Not really sneaking when she was made to be in the games. She just debuted in the manga first. Ohshima added her to CD while Naka was developing Sonic 2 in the US.
>Charmy: total manga oc who somehow got handpicked to appear in Chaotix
Nope, made for the games too.
>Mighty and Ray: designed for SegaSonic in either late '92 or early '93
This pic says otherwise.
