In addition to any politicians and celebrities depicted, the strip has several recurring characters: ;Tom Tomorrow Tom occasionally appears in his own strips as himself, breaking the
fourth wall. ;Tom Tomorrow (fictional) In an "intermediate" version of the strip, a character
named Tom Tomorrow was in the strip. He was a
private investigator who was dressed in a
radiation suit so his face was never seen. He was eventually phased out. ;Dippy the Wonder-Penguin Fictional Tom Tomorrow's sidekick. His vocabulary was limited to "wank". ;Sparky the Wonder Penguin A sort of upgraded version of Dippy (who had been phased out by the time of Sparky's introduction), Sparky is a sunglasses-wearing penguin that can actually talk. Similar to Dippy, Sparky's first words in the strip are "George [H. W.] Bush is a
wanker". A strong liberal advocate, he briefly became a
Republican after being hit on the head with a random falling toilet. ;Blinky the Dog A small
Boston Terrier who shares most of Sparky's political sympathies. Normally very mellow, he briefly became a radical when steroids were put into his food when he was intended to replace the then-Republican Sparky. ;Bob Friendly Mr. Friendly is in charge of the advertising section of
This Modern World (thus breaking the
fourth wall). It was he who introduced Sparky the Penguin. He appears only occasionally. ;Dr. Wilbur von Philbert One of the longest-running characters in the strip, Dr. von Philbert is the person who discovered how to mine reality for energy. ;Biff and Wanda Two blow-dried
news presenters of
Action McNews, a newscast in which Tomorrow suggests that most
TV news is little more than PR spin. A Biff and Wanda strip almost always ends with a cut to a commercial break ("Now, these messages!"). ;Biff and Betty Biff and Betty are two
archetypes of 1950s people, who sometimes share their thoughts on the modern world. Biff often appears alone with Sparky, expressing a naive conservative opinion which invariably prompts an exasperated liberal rebuttal from the penguin. ;Invisible Hand of the Free Market Man Invisible Hand of the Free Market Man (abbreviated I.H.O.T.F.M.-Man in dialog in the strip) is a
superhero character, wearing what is basically a
Superman costume, with an I.H.O.T.F.M.-Man logo (a hand with a letter of IHOTF on each finger, and M in the palm) where the Superman logo would be. I.H.O.T.F.M.-Man's head is a giant left hand with facial features in the palm. I.H.O.T.F.M.-Man is an ardent defender of
Adam Smith's
invisible hand metaphor, and usually intervenes in situations where the purity of
free market economics is in jeopardy. His declarations are often based on principles of free-market economics taken to their logical extreme. The first panel of a comic featuring I.H.O.T.F.M-Man is usually a parody of the cover of
Action Comics #1. Often, another character will point out that he is, in fact, not invisible. ;Conservative Jones and Moonbat McWacky Conservative Jones and Moonbat McWacky are two children used in the strip to satirize conservative talking points. Conservative is dressed as a
boy detective and asks Moonbat questions about politics. Moonbat gives reasonable answers, which the Conservative turns into illogical statements about liberals. ;Public figures All the presidents since
Ronald Reagan have appeared, as well as other political and media figures.
Rush Limbaugh is a favorite caricature subject, although he usually talks through a radio and is not personally shown. (He was once, however, depicted as a pig, in a strip parodying the film
The Mask.) Conservative columnist
Ann Coulter is often the target of particularly unflattering caricatures, usually popping up in the middle of a strip to make a typically inflammatory remark, ending with a guttural "Haw haw haw!" laugh. In a few strips,
George W. Bush gets hold of what appears to be the
DeLorean from
Back to the Future and goes back in time to meet America's
Founding Fathers.
Karl Rove and
Bill O'Reilly make frequent appearances. ;Parallel Earth The strip occasionally visits a
parallel Earth, a deliberate parody of our own world. In some strips, Parallel Earth makes wacky political choices which are exaggerated versions of real-world events. In others, the inhabitants of Parallel Earth have made sensible political choices, in contrast to the people of our own world (but wear odd, brightly-colored clothing featuring
polka dots). ;Small Cute Dog A small cute dog who was accidentally elected president of Parallel Earth in the year 2000 (and re-elected in 2004), and whose subsequent actions mirrored those of President
George W. Bush. ;Planet Glox A pair of tentacle-waving anchor-aliens host a newscast from Planet Glox, resembling Fox News. They report about news strikingly similar to that on Earth, but in factual scientific terminology (i.e.,
Coneheads-style), thereby making fun, for example, of the public obsession with the sexual activities of public figures, by referring to the global importance of touching reproductive organs.
Other recurring elements ; Supergiant Conglomerated Corporation A fictitious, stereotypical
big business or
megacorporation in an unspecified industry, but appears to represent the
military-industrial complex. This company has been portrayed as being unethical,
manipulative, obsessed with
spin, and environmentally unfriendly. Occasionally written as "Supergiant Amalgamated Corporation". ;
Action McNews The (presumably local) TV news program on which Biff and Wanda are anchors. ==In other media==
