The reasoning is propably this:Grunbeld is grunbeld, Locus is Locus,etc, but Guts is GUTS with capital letters!The protagonist of the story, and so forth and so forth.Aazealh said:Well, your comment has its place in Speculation Nation rather than here, and I'm not sure it makes sense... Zodd, Grunberd, Irvine and Locus would lose easily against Ganishka (though we don't know the extent of their power), but Guts could defeat him, based on the fact that he stabbed Slan with the DS when she appeared in the Qliphoth? I fail to see the logic in your reasoning.
It is much easier believing that the main character can (eventually) beat all enemies, than believing that some stupid band of the hawk-wannabe like locus could defeat him. This is pretty illogical, I know, but people tend to think this way(I do, even though I know it is complete bullshit) humans are weird.
