Many superheroes and their associates have surnames that are also common given names. This is almost as common as the Alliterative Name, and, in fact, many heroes qualify in both categories. This is a side effect of the American habit of using common last names as first names — most British readers would not recognize most of these surnames as first names.
This can make a Last Name Basis to be difficult to realize at first.
Jay Garrick as well, and Wally West might count, although the only West that leaps to mind is the guy fromHeroes. With Bart, at least, it really only makes sense when you realize that his full first name is actually a Patronymic (it's still very rare as a first name, though, apparently because people can't be bothered with saying anything quadrisyllabic).
Peter Parker, though "Parker" has only recently become common as a given name.
Charles Xavier (although this is pronounced differently to the first name, which is generally pronounced "zavv-ee-ay" rather than "ex-ay-vee-er"; the last name is also generally pronounced this way, but Middle America wouldn't have noticed it started with an X). The pronunciation is actually more slippery than this, as it has changed since the time of St. Francis Xavier (Which is pronounced Zay-Vee-Er, by the by). Javier is a phonetic respelling of the name in modern Spanish. However, the Portuguese pronounce the name with a sh sound.
Cain Marko is an egregious example, where a given name that doesn't make a particularly good surname is pressed into service to make a Meaningful Name. Could be completely avoided by calling him "Marco Kane" or something along these lines.
Ann Marie was the main character of the 1960s show That Girl and actually complained about her name at times.
Jimmy James, "the man so nice they named him twice," in NewsRadio.
Also Dave Nelson, Matthew Brock, Max Louis, and Jimmy's Arch-Enemy Johnny Johnson.
In Phoenix Wright: Ace Attorney: Justice for All, Max Galactica's real name is revealed to be Billy Bob Johns. Nick hangs a lampshade on it in one inner monologue. "Yikes! The poor guy's got three first names! I guess that is pretty odd."
On a recent episode of TNA Impact, the Main Event Mafia took over the show and made two referees fight Wrestling/Booker T. The referees' names were Rudy Charles and Andrew Thomas, which ring announcer Scott Steiner pointed out during introductions.
From The Mortal Instruments series, Jace, whose full name is Jonathan Christopher Wayland. We think. It's really only the last name that's a point of debate, so whether it's Wayland, Morgenstern, Lightwood, or Herondale, he's still an example.
From Muv-LuvTotal Eclipse side story, we have Rick Sven.
Madoka Kaname, Sayaka Miki, Hitomi Shizuki, Mami Tomoe, Homura Akemi, and Kyouko Sakura. Enough of them to count as Theme Naming. Hitomi and Homura are somewhat of a special case; Hitomi isn't an especially important character ('Shizuki' is not a common first name), and Homura Akemi, who is definitely important, is closer to having her names reversed than having two first names ('Homura' is even more uncommon than 'Shizuki', and if someone does use it as a first name, they're usually male).
His counterpart in the US version is named Michael Scott.
After Michael left, a number of candidates applied for his job, among which were Fred Henry, Nellie Bertram and the aforementioned David Brent. The one to eventually get the job was Andy Bernard.
Other (non-manager) characters include David Wallace, Ryan Howard and Angela Martin.
In Emma, anyone in the Martin family: Robert Martin and Elizabeth Martin.
Sayaka Yumi and her father Dr. Gennosuke Yumi from Mazinger Z. The main protagonist Kouji Kabuto also qualifies, although Kabuto is rarely used as a first name.
[Note: All the examples in this entry so far have been situations in which people have given names to characters. In that spirit, please limit entries here to people who have given themselves names (stage names, pen names, pseudonyms, etc.) consisting of two first names. Many people have a first name as a family name in real life, but this section should be reserved for people who have made an intentional choice to do so.]
Jon Stewart from The Daily Show. Inevitable, since Stewart is a showbiz adaptation of his middle name. He was born Jonathan Stuart Leibowitz.
He even makes jokes about it:
"Tonight's guest, Congressman Ron Paul, a proud member, with me, of the Two First Names Club. We, uh, we meet every Thursday for cocktails with Ron Jeremy and Barney Frank."
