Ultraman Dyna: The Return of Hanejiro
Sent by the Alien Dehadoh race, Madara's mission was to guard the Planet Earth for the incoming invasion force. However, her actions had been detected by Alien Fabiras and they launched Hanejiro to Earth to warn Super GUTS and Dyna. However, their actions were somewhat late.
She first sent out Arwon to duel Dyna but called the monster back after absorbing Dyna Strong Type's Garnate Bomber. Madara stopped time and dueled Dyna's host, easily besting Asuka as she revealed that she was the main component of Wanzetto. She then summoned Arwon again and this time fused with it with the meteorite Power Lock to become Wanzetto. The monster then easily defeated Dyna and imprisoned him in stone.
Super GUTS had no choice but to seek Alien Mijir's help as they created Pudgy Garaon. They sent Hanejiro to deliver it and the robot was dropped into Wanzetto's cranial cavity and was used sabotage its internal circuitry, destroying her in the process.
- The Android's master, Alien Dehadoh, were never shown.
- She was only credited as Alien Dehadoh Android (デハドー星人のアンドロイド Dehadō Seijin no Andoroido?) in the special as her true name was seen in Tsuburaya All Monster Photobook.
