Funko has created thousands of different products in dozens of different toy lines since its inception.The first, Wacky Wobblers, is a line of bobbleheads depicting various characters, mainly from popular culture, such as Betty Boop, Cap'n Crunch, and The Cat in the Hat. The company's mascot, a recurring character in the Funko franchise, is Freddy Funko, who was introduced in the year of 2002.

Funko's Pop! Vinyl line are figures modelled in a style similar to the Japanese chibi style.The figures have large squarish heads, disproportionately small bodies, and large, circular black eyes. The figures typically depict licensed characters from franchises such as Doctor Who, Marvel, DC, Disney, Star Wars, Wizarding World, Dragon Ball, My Hero Academia and other pop culture entities. After a preview line of DC Comics characters were released at San Diego Comic-Con 2010, the Funko Pop! line of products was fully revealed in 2011 at the New York Toy Fair.

The exaggerated body proportions of Pop! figures have invited comparisons with Good Smile’s Nendoroid figures, which are similarly described as "chibi". Both product lines depict characters from many different franchises.

Most Funko Pop! figures are not bobbleheads, as their heads do not move. However, all Star Wars figures in the line are bobbleheads, as well as most Marvel figures. This is to avoid licensing conflicts with Hasbro, the company which holds the license to make ordinary (non-bobblehead) figures of characters from these franchises.
