Ganvivormon

Ganvivormon is a Digimon.

Design
Ganvivormon is a yellow cat-like Digimon wearing glasses and a nurse’s cap with a blue cross. It rides in a pill-shaped vehicle that is inscribed with "163", which can be read as "Hi-Ro-Mi" (一六三); a play on the name of Gyotchan's wife. It wields a gun that shoots heart shaped energy waves.

Etymologies

 * Ganvivormon (ガンバイバーモン)

Development
Ganvivormon is one of five Digimon created as part of of the Digimon Adventure 20th Memorial Story project. @Gyotchan purchased one of the five ¥300,000 rewards, "Creation of your original Digimon partner & presented as a doll", which had Kenji Watanabe visit Gyotchan to create Gyotchan's partner Digimon. Gyotchan received the artwork on December 25, 2020, and received the doll at a later date.

Gyotchan came up with Ganvivormon's design from wishing for his wife to feel better whilst battling cancer during the Memorial Story Project.
