Ha! I LOVE forums where it's okay to zombie.
For some completely ludicrous reason, the thought struck me while driving home from grad school today: the bad guy's name in Ninja Gaiden I was
Guardia de Mieux. He subsequently became known as "Jacquio," and besides the obvious connation of "Guardia" de Mieux, I wonder if "Jacquio" has any solid Japanese linguistic connection to Jaki, Janus' original name before Woolsey-ization (I've always been fond of Woolsey's name choices, for the record).
Ninja Gaiden I was released for the NES in Japan in December 1988. I wonder if ideas that would later flow into
Chrono started in Kato's mind around this period?
EDIT: Oh, wait, Chrono'99 already got around to all this back in February. For quick reference:
There are other references in Ninja Gaiden I-II-III; I thought I had mentioned them somewhere on the forum but nope, I didn't yet.
Ryu's father was not killed but was brainwashed and became evil (like Wazuki).
The antagonist in Ninja Gaiden I is Guardia de Mieux, who becomes Jacquio (Jakio, "wicked king" in Japanese, while Jaki or "wicked" was Janus's Japanese name in CT).
The antagonist in Ninja Gaiden II is called Ashtar and he carries the Sword of Chaos, which feeds on blood and hatred and which was "grown out of the bone of the Demon, the same way as your sword is supposed to come from the fang of the Dragon" (Ryu's sword is the Dragon Sword). It's like the Einlanzer vs. Masamune stuff.
In Ninja Gaiden III, Ryu is framed for the murder of Irene, but it was in fact an artificial doppelganger of him that killed her (compare with Serge's murder of Kid).
The NGIII antagonist Clancy wants to use some kind of transdimensional ruins/warship to "reshape" the world. This reminds me of Lynx's plan to reshape history in RD, though Clancy merges with the warship so the Time Devourer comes to mind too. Also, he manipulated Ryu into furthering his own agenda, like how all the villains manipulated Serge in CC.
I'm hard pressed to actually add something to justify my post here now, other than exposing the post-C&D Compendiumites to the basic framework of Masato Kato's development. How about this mysterious reply we received at GameFAQs in the C&D aftermath?
(That was not Photoshopped by the way;
you don't even have to trust me -- the question is whether it was a hoax, or if Kato himself had descended from Mount Nippon to bless all believing Compendiumites).
Also, I've begun wondering how the XBOX Ninja Gaiden series would have turned out if the scenario design were once again given to Kato. Ninja Gaiden 2003 has to be one of the greatest action games I've ever played, but it was extremely lacking in the story department.
