I remember feeling of awe as a six year old when I realized I could put three toa together, and the storyline significance behind it. Toa were already essentially demigods, but the Kaita were truly mythic. I'd always thought of Akamai and Wairuha as a merging of the original six Toa, but that they also trancended them. They were two wise and courageous beings the Toa could act as a conduit for and could tap into in times of dire need. Seeing Bohrok and Rahkshi use the same methods to form their own Kaita just raised the stakes even more for the heroes. Their distant brothers or twisted foes could reach the same heights of power and strength. I never liked the idea of matoran or turaga forming kaita (nui?) though, since (for me at least) the whole appeal was seeing the great (good or evil) join together to become even more. In a similar vein to what HoloTheWise said, I think I can blame that desire on watching DBZ. I think the idea was underutilized, and there could have been good stories to tell about them but I'm glad they didn't, because it would have been far too easy to feel "gimmicky." Plus, I can't exactly say I miss Wairuha or Akamai since they had little to no development in their own right.

I voted "Not Sure" because while I don't think it should be able to see through walls (which has nothing to do with night vision) multiple vision modes aren't a bad idea for a great mask designed to see in the dark. Instead of x-ray vision, it would make sense for the wearer to see the world as if it were illuminated (regular night vision, which it already has) or pick up heat signatures (thermal imaging). A variety of animals utilize one or the other to help navigate dark or underground environments, and militaries use both types depending on what's tactically appropriate. With thermal you could also pick up a heat signature through something if what's obscuring it was thin enough, which is a more logical alternative to straight up (albeit limited) x-ray vision.

I always felt Hapka's ending resonated better with the overall theme of the book. The Toa started off seperate and untrusting of one another, and throughout the story they realized no man is an island (except for Mata Nui, I guess) and made the transistion from six lone wolves to a cohesive team and mastering their respective powersets, proving they had the right stuff to save the day. Greg's version has them coming to terms with their dark side, but I never felt they really had any true inner darkness to address in the first place and it didn't thematically fit.
