Countryballs

Countryballs, also known as Polandball, is an art style and internet meme used in some online comics in which countries are typically personified as imperfect spherical characters (there are some exceptions such as Nepalrawr, Israelcube, Kazakhstanbrick, and Tringapore) decorated with their country's flag. The characters often interact in broken English, and the dialog typically uses regional and/or national variations, depending on the region the character represents (e.g., Franceball's broken English is interspersed with French words). The comics poke fun at national stereotypes, international relations, and historical conflicts.

Planetballs
Planetballs are circle-drawn characters in the Polandball universe, similar to countryballs. They represent planets, moons, dwarf planets, stars, star remnants, black holes, and even parallel universes. space proves and asteroids also appear but they aren't drawn in ball shape. They have been a little-known staple of Polandball since its founding on Krautchan, they can be crossed over with polandball comics (e.g: Sunball making a cameo in a comic about Germanyball & Swedenball).
