mine are:
1.) Geoffrey St. John - Though he was in one previous issue, I think he should return to possibly become Sonic's rival again.
2.) The Brotherhood of Guardians - I think they've been in the Twilight Zone long enough. Other than characters mentioning them & the recaps, they haven't officially have been seen for what, about nearly nine years in the series?
3.) Zonic (Zone Cop) - a brief appearance in #197, he should come back along with a couple alternate reality stories (well, I guess that's why we have Sonic Universe then.
4.) Tommy Turtle - no, just kidding! He was just like Nate Morgan, both showed up for awhile, then had similar fates.
