Rider Haggard), Dr. Jeckyll/Mr. Hyde (of Robert Louis Stevenson's short story), and the Invisible Man (of H. G. Wells' novel). Dorian Gray also appeared through out the first comic series, but was not a member of the LXG. A new Invisible Man was used in the movie when they could not secure the rights to Wells' version. Tom Sawyer was added by the movie producers, presumably because an American audience wouldn't care for an all British cast. Movie did not live up to the comic (by Alan Moore) in any sense.
Magneto Eric Lensherr Marvel Movies, TV (animated) Main rival to Professor X and his X-Men. Was held in the Nazi concentration camps.
Man-Thing Ted Sallis Marvel Movie Only appeared in a direct to DVD movie. The character is very similar to Swamp-Thing, whose creator was the roommate of the creator of Man-Thing. The fact that both pitched similar ideas to the two biggest comic companies at the same time was said to be coincidence. Technically, Man-Thing appeared before Swamp-Thing.

The character is very similar to Man-Thing, whose creator was the roommate of the creator of Swamp-Thing. The fact that both pitched similar ideas to the two biggest comic companies at the same time was said to be coincidence. Technically, Swamp-Thing appeared after Man-Thing.
Teenage Mutant Ninja Turtles NA Mirage, Archie, Dreamwave, Image Movies, TV (live action and animated) The original, Mirage version of the Turtles were created as a parody on the number of comic books that featured mutants (the X-Books) and ninjas, yet was written vastly more violent and more mature than what later made it into mainstream media. A comic book by Mirage still exists using the original versions of the characters, while a TV show featuring the more popular version of the character still exists.
(New) Teen Titans NA DC TV (animated) Teen Titans members include Aqualad (Tempest), Wonder Girl (Donna Troy), Robin (Nightwing), and Speedy (Arsenal). New Teen Titans members include Cyborg, Nightwing, Starfire, Changeling, Raven. The New Teen Titans cast was used for the Teen Titans animated show, except Nightwing was still called Robin, but was dressed in the Tim Drake Robin costume.
V for Vendetta NA Vertigo / DC Movie The theme of the movie was democracy vs fascism (or liberalism vs neo-conservatism), while the theme of the comic was anarky vs totalitarianism. Comic was written with much more moral ambiguity than seen in the movie by Alan Moore, who thus disapproved of the deviation from his work. After the Wachowski lied about this in a press release, Moore requested his name removed from all publicity for the movie and any monies he would receive to go to the artist of the book.
Wolverine James Hewitt Marvel Movies, TV (animated) Commonly referred to as Logan by his friends (before he remembered his real name). Most popular member of the X-Men, and has even been a member of the Avengers and a temporary version of the Fantastic Four. Main rival is Sabretooth.

Rivals include Magneto, Apocalypse, Mr. Sinister, and the Sentinels.

Because A couple of people I talk to have been confused, and because I was bored, I have compiled a list of many comic book characters that have made their way onto television or the movies. I have also tried to give some basic background information on either the character or the medium they were created it where appropriate. This list only contains movies/television shows where the original medium was a comic book, and does not cover works that have crossed over into comic books (e.g., Aliens, Star Wars, CSI, Nightmare on Elm Street, Buffy).

To clear up any confusion, DC comics has many imprints under it, such as Vertigo, WildStorm, and America's Best Comics. Characters within these imprints never cross over into the main DC universe, with rare exceptions of a few Vertigo characters (mainly because some Vertigo characters use characters that were created before Vertigo was created, such as in the case with Swamp-Thing).

As one might be able to tell, Alan Moore hates when someone makes a movie out of his work.
