Protoplasm

Protoplasm is a free distorted display font from Iconian Fonts, with letters that look pulled from slime, ink, or some half-grown organism. The caps feel wet and unruly, with torn edges, swollen curves, and irregular gaps that make the whole font read like a mutating sci-fi horror title rather than a neat set of shapes.

That makes it a natural fit for poster work, game logos, zine covers, Halloween flyers, and B-movie title cards where a free font needs a strong creature-feature mood right away. It also works well for short headlines, band marks, and big monogram-style initials, because the letters carry enough ooze and damage to hold attention without extra effects.
