A long time ago I got the PowerPack.(The CD with the 3 tracks.) and then before that I got Lewa and got the mini CD. First of all, The instructions of the toa show that Kopaka and Pohatu are near each other on the back. The stones showed in the Mini CD and the Episodes on Bionicle.com form a ball. On the Great Map of MataNui shows the stones and Who owns them. Kopaka and Pohatu own the same section of a the stone sphere. and there name has the same exact lettters. And that BZ puts Kopaka and Pohatu next to each other.

Just Joking...hehe...I don't know what but they have something incomen. See if you guys can figure it out...I think that they have an extra hook-up. Like Pohatu has an upside down body and hammers on his legs and Kopaka has a sheield and that grey neck.

Mabe thats it....
