10 Franchises Kept Alive By Comic Books
3. TMNT
Seeing as the team started off as comic book characters, you'd expect the medium to be the thing that kept them relevant, and you'd most certainly be right.
Probably due to the dreadful movies of recent years, the Turtles have been lacking in terms of on screen content, making the comic series pretty much the only place to find the team (at the time of writing).
So, in the group's title the Turtles have enjoyed some great writing across their hundreds of terrific tales. As well as the main book, the group have even gone as far as to team up with (and fight against) DC icons Batman and Robin and also the other IDW title, the previously mentioned Ghostbusters.
