|This article is about a/an villain in Hikonin Sentai Akibaranger.|
Doctor Z (ドクターZ Dokutā Zetto): Doctor Z is the Blatantly Evil Marketing Firm B's head. His true identity is Takehiro Tsuzuki, Hiroyo's father who was a brilliant scientist admired by his peers until he becomes obsessed with becoming an anime illustrator. After scouting for opportunities without success, Takehiro managed to land a job as a character designer for the Z-Cune Aoi anime series, but his rough and violent sketches (including those of ©Na) were rejected by the studio and he was fired.
He first appeared as the Mysterious Man (謎の男 Nazo no Otoko), a long-haired vagrant who witnesses the Akibarangers' battle with Tsukishima Alpaca in Akihabara. He is given Yumeria's business card by Akiba Yellow, which he passes to ©Na.
It turned out that he isn't the real enemy and when ©Na tried to talk to him about her and Nobuo's discovery, his personality began changing (represented by the flickering of the screen).
After the Akibarangers accidentally defeated Delu-Knight, he reunited with his daughter despite her fear that it was part of "His" plan to end the show.
- He resembles some Shōwa period villains, particularly Doctor Man from Bioman and Doctor Shinigami of Kamen Rider. Also, his name consisting of the title 'Doctor' followed by a single letter is reminiscent of Doktor G, a villain in Kamen Rider V3, who recently appeared in Kamen Rider × Super Sentai: Super Hero Taisen as Nartuaki's alter ego.
