*** Compare his roles as [[Anime/HeroicAge Age]] and [[LightNovel/SpiceAndWolf Kraft Lawrence]] and see if you can tell that's the same man.

* Kraft Lawrence in ''LightNovel/SpiceAndWolf''

* Shiro/Kotarō Yanagisawa in ''Manga/AssassinationClassroom''

Is known to be [[JustForFun/OneOfUs a huge nerd]] who is particularly enamored with classy things like Literature with a capital L. Namely, really thick books and Creator/WilliamShakespeare. He once read ''Beowulf'' in Old English. This works to his advantage whenever they need a script writer for a show with tons of intellectual content or sophisticated grammar (''Manga/HeroTales'', ''Manga/OuranHighSchoolHostClub'', ''VisualNovel/SteinsGate''). However, he is also a fan of many other considerably more intellectual things, such as ''Series/DoctorWho''. He is the only dub cast member of ''WebComic/HetaliaAxisPowers'' who can actually speak the native tongue of his assigned character authentically; France (aside from America and England, of course).

* Paul von Oberstein in ''Anime/LegendOfGalacticHeroes: Die Neue These''

* Mr. Foster in ''Videogame/KillingFloor2''
* Sir Hammerlock in ''Videogame/{{Borderlands 2}}''

He's also been engaged to another fellow voice actor, Brandon [=McInnis=].

* [[Characters/SteinsGateRintarouOkabe Rintarou Okabe]] in ''VisualNovel/SteinsGate''

* Rintaro Okabe in ''VisualNovel/SteinsGate''

* PigeonholedVoiceActor: Either TheStoic or the {{Villain|s}}. However...
** ManOfAThousandVoices: Fans will argue that his voice work as France in Hetalia (which requires him to pull off a French accent) helped his vocal range greatly. The director of the dub said Tatum was the only cast member who could actually do an authentic accent of his character, even though he wanted him to go with an exaggerated, [[TheWarOnStraw Strawman]], funny one.
*** Compare his roles as [[Anime/HeroicAge Age]] and [[LightNovel/SpiceAndWolf Kraft Lawrence]] and see if you can tell that's the same man.
*** If a character wears glasses and is the smart one of the group, chances are he's voicing them.
*** He had a speech impediment as a child and was trained to talk properly under a woman from the UK. Explains a lot.

* BadassBaritone: Particularly as [[Anime/FullmetalAlchemist Scar]].

* Oliver Schtrom/[[spoiler:Oliveira von Schtradius]] in ''LightNovel/TheWiseGrandson''

* AbsurdPhobia: Clowns. Even the non-creepy ones. It becomes a running joke on ''That Anime Show'', and he cannot listen to Sonny Strait's scary voice for Drossel in ''Black Butler''. He almost threatened Halloween fair staff members dressed as clowns who were following him.
** At one panel at Another Anime Con 2016, Tatum said he is no longer afraid of clowns.
* EndearinglyDorky: In real life. However, he tends not to play these characters very often in fiction because of the lower register of his voice. (Exceptions include Tenya Ida in ''My Hero Academia'', etc.)

* FakeBrit: Has a very good British accent, as ''Black Butler'', ''Killing Floor 2'', ''Borderlands 2'', and ''Ouran'' show.

* GentleGiant: At 6 feet and 3 1/2 inches, Mr. Tatum is possibly one of the nicest people in the voice acting industry, and he's super jolly, sweet, and incredibly friendly to his fans.
* IResembleThatRemark: During his work on ''My Hero Academia'', fans and cast members have pointed out that Tatum shares similar character tics and traits with Ida (the most prominent one being gesticulating with his hands when emphasizing points he wants to get across).

* TheNicknamer: He gives all his guest-stars a nickname on ''Podcast/ThatAnimeShow''.

* PlatonicLifePartners: With Terri Doty.

* TheStoic: Some of his characters are like this, particularly Kyoya.

* StraightGay: Oh yes. He lived with his then-boyfriend for 12 years. It never gets in the way of his career because he believes that it's a non-issue. In fact, he has more than a few fangirls who love him for this just as much as they love him for being Sebastian.

* [[Characters/BlackButlerSebastianMichaelis Sebastian Michaelis]] in ''Manga/BlackButler''

* Scar in ''[[Manga/FullmetalAlchemist Fullmetal Alchemist: Brotherhood]]'' (as well as the Chibi Party OVA)
* Sebastian Michaelis in ''Manga/BlackButler''
