Okay, so this is a genuine question since I know jack all about Bionicles since it's been **AGES** since I've watched Bionicles and although I liked it I wasn't a diehard fan so I haven't kept up with it.   
  
So since the beginning of this debate people have been discussing which Kraata can Tahu use that's actually effective against Kai, stating all the different types that he can use since supposedly he can use all 42 Kraata types via Golden Armor. But recently, it has come to light that Tahu might not actually have all 42 Kraatas. There are two evidence for this, firstly is in the actually story, in that the Golden Armor gives Tahu access to Kraatas via absorption from defeating a Rahkshi and that in the ending of Bionicles he's only seen defeating a dozen or so different types of Rahkshi which are not enough to confidently say he had obtained all 42 types of Kraata before the big bang nuke explosion. The second thing that supports this is that one of the writer's corrobarated this and flat out stated that Tahu only had the confirmed Kraata of Heat Vision and Quick Healing and that he shouldn't have more than a few before the ending.   
  
My question is 1) is this all true? 2) how do we justify which Kraata can he use and which one he can't, since we know for sure that he at least have some, more than the confimed two, but also not all 42 Kraatas and have never seen him use any of them? and 3) how does this affect the debate against Kai if he doesn't actually have access to the majority of his Kraatas?
