大長編ドラえもん (Daichōhen Doraemon/Doraemon Long Stories)

Plot

The first 16 volumes were adapted into animated movies after serializations, while the remaining eight volumes were based on the movies.

Its creation and productions were presumably influenced by Time Patrol Bon where Fujiko focused on the Long Stories after ceasing Time Patrol Bon due to his health issues, and there have been notable similarities between plots of the franchises.[1]

The first 17 volumes of this series were written by Fujiko F. Fujio himself, while the last 7 volumes were written by Tadashi Haziko based on the drafts of Fujiko F. Fujio and illustrated by Hagiwara Nobukazu.
