If i have to list the MANY serious that has inspired me i would have to list them in different category.
Books:
The Chronicles of Narnia Series, The Witcher series (i've just started reading the books), The Magic Tree house series (my childhood series that i have read a lot), and HP Lovecraft: The Shadows Over Innsmouth (which inspired something i will list in a bit.)
Anime/Manga:
Berserk, Kenichi The Mightiest Disciple, Bleach, My Bride's a Mermaid, Hetalia, Fairy Tail, Durarara, Full Metal Alchemist (both the original and Brotherhood), Demon Slayer, and Made in Abyss.
Video Games:
Spyro The Dragon (the original trilogy), God of War, Devil May Cry, The Metal Gear Series, The Legend of Zelda, The Dark Souls Series, Bloodborne (which has many inspiration of HP Lovecraft), Sekiro Shadows Die twice, and Halo.
All that i have listed have inspired me to be a writer and an artist to try to tell my own story. and they all have inspired me in so many ways.
