How can I modify a standard font to create a comic book style?

To modify a standard font, you can alter letterforms by adding serifs, changing stroke thickness, increasing x-height, or adding stylistic alternates. Font editing software like Glyphs, FontLab Studio, or RoboFont allows for more complex modifications. Alternatively, you can use online font editors for simpler changes. Consider resources like FontStruct for inspiration on building custom letterforms.
