Fear the walking Dead does have its roots in a comic. The comic provides the framework and inspiration for the TV show, with some creative adaptations made for the screen.
One popular one could be 'Cinta di Ujung Senja'. It tells a heart - touching love story between a young man and a woman in an Indonesian setting with all the cultural nuances that make it special.
There's also 'The Unseen Heroes' which is a fanfiction that explores the stories of the background characters in 'Fear the Walking Dead'. It's fascinating as it shows how these often - overlooked characters can have important roles in the overall apocalyptic world of the show.
