M.D. Geist I: Most Dangerous Soldier

M.D. Geist I: Most Dangerous Soldier (装鬼兵MDガイスト Sokihei M.D. Geist) is an anime OVA film produced in 1986, created by Koichi Ohata and directed by Hayato Ikeda.

M.D. Geist was originally released in North America as a sub-only VHS in 1992 by Central Park Media; two years prior, the company used Geist as the logo for their mainstream anime label U.S. Manga Corps. Curiosity by fans over the logo boosted domestic sales of the OVA and prompted Central Park Media to collaborate with co-creator Koichi Ohata in producing a Director's Cut, featuring roughly five minutes of additional footage - including a new introduction and epilogue that paved the way for the sequel.
