Well, this fan fic is a fantasy, and for some reason I always though that a Guyver/Twilight crossover would be interesting. There are other things that are going on in my fan fic, too (of which some chapters are in another topic in this area of the forum), such as Shizu becoming a vampire hybrid that makes her immortal and enhances her Zoalord abilities though her being reprocessed. That's not canonical to Guyver, really, aside from reprocessing is the only way to keep Shizu alive longer term.
In some ways, Camel especially and other vampire hybrids can be compared to Zoalords and Camel in a way is very similar to Aptom due to him picking up and using abilities from other creatures. Only difference, he doesn't have to "eat" them. Drinking blood or coming into contact with their DNA (BTW, Camel tends to kiss women to get their powers, which is why his wife--another hybrid--seem to be the dominant power he's gained), is sufficient.
Just like how Sho spawned the Gigantic and Gigantic Exceed armors out of a desire to vanquish evil, Camel spawned some of his ability out of emotional trauma, pain, anger and a desire to end suffering and punish the wicked. So Camel is a freak, sorta like Aptom is. But we have to remember that the freakish mutation known as Aptom is nearly as powerful as a full-blown Zoalord and can damn near kick anyone's ass he sees fit, and being insanely versatile as a creature of combat. He slices, he dices, he'll rip your nuts off! Camel is the same in that way, but not quite as much of an anti-hero...to an extent.
I am, after all, writing this for fun and it's not really to be taken seriously. If people like it, fine, if not, that's fine too. But it's not something to be taken all that seriously by anyone, whether or not they like it.
