10

John Fleck

5+ credits: Taibak (TNG: "The Mind's Eye"), Cardassian overseer, uncredited but with dialogue (DS9: "The Homecoming"), Ornithar (DS9: "The Search I"), Koval (DS9: "Inter Arma Enim Silent Leges"), Abaddon (VOY: "Alice"), Silik (ENT).

John Fleck could be seen in increasingly important roles, culminating in the recurring character of Silik in Enterprise.

John Kenton Shull

6 credits: Klingon actor (TNG: "Firstborn"), Bajoran security deputy (DS9: "Shakaar"), Hanonian medicine man (VOY: "Basics II"), K'Temang (DS9: "Return to Grace"), Brok'tan (VOY: "Barge of the Dead"), Nocona (VOY: "Homestead").

John Kenton Shull can be seen in six credited roles altogether.

8

Paul S. Eckstein

6 credits: Limara'Son (DS9: "Rocks and Shoals"), Young Hirogen (VOY: "The Killing Game I+II"), Supervisor Yost (VOY: "Gravity"), Jem'Hadar guard (DS9: "The Dogs of War"), New Alpha Hirogen (VOY: "Flesh and Blood"), Morak (VOY: "Prophecy).

Paul S. Eckstein too is credited in all six of his Trek roles but remains unnamed in some of them.

7

Joseph Ruskin

6 credits: Galt (TOS: "The Gamesters of Triskelion"), Tumek (DS9: "The House of Quark", "Looking for par'Mach in All the Wrong Places"), Cardassian informant (DS9: "Improbable Cause"), Son'a officer ("Star Trek: Insurrection"), Vulcan master (VOY: "Gravity"), Suliban doctor (ENT: "Broken Bow").

Joseph Ruskin (1924-2013) is one of the few veteran actors who appeared both in TOS and in the second generation of Trek, and the one with the most different characters (ahead of Clint Howard).

6

Thomas Kopache

6 credits: Mirok (TNG: "The Next Phase"), Train engineer (TNG: "Emergence"), Viorsa (VOY: "The Thaw"), Kira Taban (DS9: "Ties of Blood and Water", "Wrongs Darker Than Death or Night"), Tos (ENT: "Broken Bow"), unnamed alien (ENT: "Harbinger"). Honorable mention: Kopache could be seen on the bridge of the Enterprise-B in "Generations" in an uncredited small role.

Thomas Kopache is not such a well-known name in the fandom, but the mere fact that he appeared six times on Star Trek is impressive. Yet, there are still four other actors with six roles that were more notable.

5

Paul Boehmer

6 credits: Nazi officer "Kapitan" (VOY: "The Killing Game I+II"), One (VOY: "Drone"), Vornar (DS9: "Tacking Into the Wind"), Mestral (ENT: "Carbon Creek"), Nazi officer (ENT: "Zero Hour"), Nazi SS officer (ENT: "Storm Front").

Paul Boehmer appeared as six different characters, among whom at least One from VOY: "Drone" is very memorable, but he also has the questionable honor of playing the most Nazi roles on Trek.

4

Randy Oglesby

6 credits: Scholar/Artist in Riva's chorus (TNG: "Loud as a Whisper"), Ah-Kel and Ro-Kel (DS9: "Vortex"), Silaran Prin (DS9: "The Darkness and the Light"), Kir (VOY: "Counterpoint"), Trena'L (ENT: "Unexpected"), Degra (ENT).

Randy Oglesby played five guest characters until he got his first recurring role on Star Trek as the Xindi-Primate Degra, which earns him the overall fourth place and the third place among the actors with six roles.

3

J.G. Hertzler

6 credits: Vulcan captain (DS9: "Emissary"), Martok (DS9), Laas (DS9: "Chimera"), Hirogen fighter (VOY: "Tsunkatse"), Kolos (ENT: "Judgment"), Klingon captain (ENT: "Borderland"). Hertzler also voiced the Drookmani captain in LOW: "Terminal Provocations" and "A Mathematically Perfect Redemption".

Among the various actors with six different parts on this list, J.G. Hertzler is the runner-up. He has an additional voice acting credit and he played General Martok after all!

2

Jeffrey Combs

6 credits: Tiron (DS9: "Meridian"), Brunt (DS9), Weyoun (DS9), Penk (VOY: "Tsunkatse"), Thy'lek Shran (ENT), Krem (ENT: "Acquisition"). Honorable mention: His voice for the evil computer AGIMUS in LOW: "Where Pleasant Fountains Lie" and "A Mathematically Perfect Redemption".

Jeffrey Combs, like J.G. Hertzler, appeared in six different roles and voiced one animated character. I put Combs ahead of Hertzler because he had three recurring parts and appeared in overall more episodes.

Vaughn Armstrong

11 credits: Captain Korris (TNG: "Heart of Glory"), Gul Danar (DS9: "Past Prologue"), Telek R'Mor (VOY: "Eye of the Needle"), Seskal (DS9: "When It Rains...", "The Dogs of War"), Two of Nine aka Lansor (VOY: "Survival Instinct"), Vidiian captain (VOY: "Fury"), Alpha Hirogen (VOY: "Flesh and Blood"), Korath (VOY: "Endgame"), Admiral Forrest (ENT), Klingon captain (ENT: "Sleeping Dogs"), Kreetassan captain (ENT: "Vox Sola", "A Night in Sickbay").

Wow. Now that is impressive! With 11 appearances, Vaughn Armstrong easily (and not unexpectedly) tops the list of the actors with the most different Trek parts. An unsurpassable record?
