I'd throw Aulbath in there, somewhat. While his dash pressure game is immensely better, he can be very annoying when the McFish player can zone you out right and makes you land on a poison or a sonic wave. But that's a real risk compared to other characters who have a better zoning game.
Although Demitri has your "shoto standard" zoning game, I think Lei Lei has the best overall zoning game, because she has two special moves (ES Gong and Projectile) and an entire Super that are geared towards zoning (LaoRai Tenshin [swords]). Other characters that can kinda hang back are Morrigan (somewhat) and Anakaris (somewhat). But as Skankin Garbage mentioned, zoning and turtling in Savior takes a sort of backseat to rushdown. Characters who can break zoning are more than capable of sheerly overwhelming overly defensive players by the speed and angle of their rushdown (Sas, Raptor, QB are the biggest culprits).
