If Guyver is known for one thing, it's not making too many characters 2 Dimensional, though the early OVA's made viewers think otherwise. I actually like the fact that since relics arc, the villains have been given full character development treatment too. Originally you don't know much and have to assume they are greedy darwinists megalomaniacs, but it's changed since then... well except maybe for Guyot, he;'s still all that... Barcus might be heartless to the rest of humanity, but he cares for his friends and duty. He's a great antagonist who as it turns out is someone you would trust with your life if he were your friend, but a frightful enemy.
