Moldiver (モルダイバー) is a 6-episode 1993 OVA anime series. It is a parody of magical girl and superhero anime series.
The series in part resembles the basic premise of the DC Comics superhero Hourman. An inventor finds a way to grant superhuman abilities to individuals, but these abilities only last for a very short timespan (60 minutes for Hourman, 11 minutes for this series). The inventor creates a superhero alter ego for himself, but his sister tampers with the power-granting device and creates a more feminine superhero costume. She reluctantly becomes a superheroine in order to stop the schemes of a malicious roboticist, the roboticist's private army of destructive robots and androids, and the attacks of her own younger brother who chose a supervillain career because he dislikes both of his heroic siblings.
Plot
The plot focuses on a young girl by the name of Mirai Ozora, living in Tokyo in 2045. Being obsessed with her hobbies of shopping and modeling, one would never expect her big brother Hiroshi to be a brilliant inventor for ZIC, a major technological corporation.
It all begins with Hiroshi's invention of the "Mol-Unit", a device capable of allowing an object to operate outside of the normal laws of physics. Flight, super-speed and strength, invulnerability, all capable through the Mol-Unit's power. The only catch, however, is that it can only stay active for a limited time, only 666 seconds (just over 11 minutes).
