Soooo here's how this will work and what to expect in the next story I'll be doing.
In the fic named "Guyver US: Origins" you will read about basically the same plot overall that happened in Mutronics BUT with a large has hell exception. The Guyver will be used like it was directly from the Comics of Takaya. Yes Sean will know self defence but when he bitch slaps a human the guys head will fly off killing him instantly. Gone will be the comedy and crap but the story will stay largely the same.
It will borrow some elements from the comics in that a new character will be introduced that will be a fore runner to Enzyme 1, something that can die and actually disolve a Guyver... not it magically happening itself.
Most important changes will be a heavy backstory to Fulton Balcus the Zoalord in Mutronics. Fulton will still be a Zoalord made byt he Creators. But he's no longer a combo of Alkanphel, Guyot and Valkus but a stand alone character that has to fit into the Guyver books. As such he'll be a Uranus made prototype of a Cotnroller before Alkanphel was made. He is based on reptiles for his zoaform which explains his Zoalord Form. But unlike the movie it will be a lot more lethal and fast. He will use shielding (that would take a full double mega-smasher to kill him because of) and more of the basic powers common to Zoalords.
how he fits into Chronos is the next plot and more so how he fits into the Comics and the fic correctly. Fulton Blacus awoke like discribed in the movie. But in more recent times. LA was founded in 1781, as such it's a recent development and gives room to the following idea. Fulton Balcus awoke recently within in the last 100 years. He founded Max Pharmaceuticals in LA. It grew and make zoanoids based on information he had in the site he awakened in that also had a dormant Unit he kept secret. Max Pharmaceutical in the late 80's came into contact with Chronos. by this time the 11 had already decided on and already had the Zoa-crystal for Guyot who would be the 12th Zoalord of Chronos. It was decided for Fulton to remain outside of the 12 but a respected Zoalord none the less. Equal in rank to that of Valkus who was viewed second only to Alkanphel.
To tie this more into the fan-fiction and explain the differances in comic and movie stories Fulton will be tied more into the fan-fiction for history. Fulton unlike Alkanphel hates the Gen instead of the Uranus. The Gen used the Utah relic has a test ship (also a for a source of Unit's to use against the Guyver Zoalord much later on). The Gen used information they got from Fulton to find that ship and also Alkanphel (who would have seen Fulton killed off possibly has an uneeded prototype). The Gen used Fulton in their tests of the potyo-type Guyver's. In a battle with the Primitive Guyver (which saw the Relic in Dark Hero's flash backs damage) Fulton was badly hurt. Like Alkanphel he hid in a damaged ship but the damage ship was located in what is now LA. The Unit Fulton took from Utah he could not activate. Unaware it had already being modified by the Gen like all Utah Relics to only activate on lesser zoaforms/humans.
this will also give an insight to the Creation of Zeugma (someone again who Fulton hates) that they created from genitc info they got from the sleeping Alkanphel. Yes the Gen knew of him, but viewed him too damaged to be of use and Fulton has basically... a "forgotton needless prototype".
In modren times Dr. Tetsu Segawa was trying to figure out a way of unlocking it so Fultron could use it. Fearing this he took the only known unit Fulton had access too. The Utah Relic since being covered in Rock being impossible for him to find.
Much lik the movie Fulton in the end will try to remove the Unit G from Sean with his mouth... this gives an opening for Sean to put an end to him with a full Mega-smasher. But the fight will be a much tougher fight not just some giant thing running around that Sean jumps on to cut off an head spike....
"Dark Hero" ties in much easier. Only minor changes to fights to show Sean is more used to his Unit after learning more about his weapons from the fight with Fulton though holds back from using his full powers at times, the unit that pushes him to fight has it puts it (really his own self), that part of him enjoys kicking them around the place.
Overall nothing much needs to change here, only it's Guyot who is the zoalord Crain is talking too. Guyot was sent to clean up the mess of Chrons LA. It was from him he got the idea of getting a Guyver unit. It's from captured research from Dr. Tetsu Segawa that he also learned that the Guyver US was not worth his attention personally because possibility that the Creators modified the unit and that Fulton aluded too there being the possibility that they where modified to stop him or another Zoalord from using them. As such he was trying to fix this block and was looking at Chronos research on Relics point and their newly required Unit's to find the answer to Unlocking Fulton's. Though if he could have the Unit it was still worth it.
In the end Crain failed, he went to Japan and destroyed his research on LA so Chronos didn't know of his plans for the US Guyver and hoped to capture the Japanese Guyvers who reepesented a more appealing target being unmodifed units.
Sooo thats where I am at the mo idea wise for the next story.
I love it! Sounds awesome to me. I had once played out similar ideas in my head, but not into much detail as you have. Accept in mine, Sean ended up being refered to as Guyver 0. lol. But in WG, the title is already taken.
But your ideas fit in perfectly well with the Takaya main-stream story.
As for the ship that Crain got his unit from, will you have it destroyed from Sean's Mega Smasher, will he still send it away, or will it have any real effect in the future at all of the fic?
