Nakayama seems to be nothing more than a poor cabby and a loving
grandpa to Noboyuki, whom he raises after the boy's mother has died - but
the evil Iron Cross Army has found out that until 5 years ago, he was a
master thief, and he has stolen the most valuable diamond The Eye of
Egypt ... and since the Iron Cross Army is quite so evil, Nakayama is
captured and tortured so he can be made to give away his secret ... but he
remains mum. When Nakayama tries to get away, he is killed ...
(Yukie Kagawa), second-in-command of the Iron Cross Army figures that
Nakayama must have somehow passed the location of the Eye of Egypt on to
his grandson and has him captured - but Noboyuki is a friend of Spicer-Man
(Shinji Todou), who naturally saves the boy. So the Army produces a body
double of Nakayama to convince Noboyuki to talk, and it works, Noboyuki
hands a locket containing a map to the diamond over to his grandpa's body
double, and learns he has made a mistake only way too late. But of course,
Spider-Man interferes again and defeats the Iron Cross Army and its giant
guest monster, also with the help of his giant robot Marveller/Leopardon.
The locket witht he treasure map gets destroyed in the fight though, and
the Eye is lost forever after, and Spidey doesn't have the nerve to tell
Noboyuki that his grandfather once was a master thief ...
rather forgettable Spider-Man episode, putting way too much
focus on the cheesy aspects of its story to remain even remotely
interesting. Plus, another episode that proves my point that the Spider-Man
stories featuring little boys are among the weakest.
