THWACK, by Jim Kalogiratos of Black Mantis Operations, is a free comic-book action display font with the blunt force and slanted rush of a sound-effect headline. The letters lean forward in heavy, jagged shapes, with sharp notches and chopped angles that make the caps feel punched out of a fight scene rather than neatly drawn.
It fits posters, zines, game graphics, skate flyers, and title cards where a word needs that impact-first snap; as a free font, it also makes sense for comic cover lines and short merch slogans. Use it when you want the caps to hit hard and fast, because the rough diagonal cuts keep even a short word looking loud.
