Actually, Frenzied Berserker seems like a great fit overall, due to the increased power attack and the ability to simply not die do to damage.
I chose Whirling Frenzy because it gives an extra attack (which I think might stack with the extra from Frenzy) and increases AC, whereas normal rage decreases AC; while he does take a lot of damage, he also avoids a whole lot of attacks, he's very fast in battle and manages to avoid all kinds of attacks that would kill him.
Frenzied Berserker was definitely the first thing that came to mind... but I'm a little uncertain about it. Spoiler

Frenzy is basically what the Berserker Armor does; though alternatively, maybe he could be a FB and the Armor could augment his frenzy/rage or something.

His weapon isn't magical, per se,Spoiler

though it has some supernatural qualities after slaying so many apostles
. He really doesn't pounce either, though leap attack is good; he does most of his fighting in place, not charging around and inexplicably making several attacks in midair.
Also, we should keep in mind that Berserk is a very low-magic setting.
Edit: Also, on the magic sword issue; remember that part of what makes Guts so hardcore is that he's able to damage his non-human opponents, where basically no one else can, i.e. he hits so hard that he can overcome high damage reduction; he doesn't bypass it... well, he might now(see above spoiler).
