...so my only question is "What else is there to know about the greatest thief in the world?"
Wow. That's a big question. Basically, the stuff on the homepage is what everyone will agree on with you. After that, it's your own interpretation.
The interesting thing about Lupin is that it's quite diverse without even trying.
Monkey Punch had his own version of Lupin when he first started drawing Lupin. His Lupin manga was actually very different from chapter to chapter, nothing really was transferred to the next week. This holds true for the movies and TV series. So, however all subsequent directors of Lupin had their visions of the Gang, that's how it was until the next time.
So actual questions like:
"Is Jigen from the mafia?"
"What is Goemon's sword made of?"
"What is Fujiko's and Lupin's relationship?"
"What is Zenigata's personal life?"
They can never be truly answered.
For example:
Watching "The Secret of Mamo" movie will leave you beleiving
that Zenigata has a wife and daughter. While watching "Steal Napoleon's Dictionary!", Zenigata himself says That no woman has loved him for 20 years. And in "Die! Nostradamus!" He laments over his pushing aside of women over the years, and abandonment of his parents for pursuing Lupin.
The Lupin franchise sometimes contradicts, sometimes supports itself. So what more is there to know? Well, that depends.
