Kopaka was ahead of his time, utilizing a piece that would eventually become the hand for all Toa until 2008. I was always bugged that Pohatu's hands weren't brown. I swear, sometimes I felt like the Toa of Stone was just some weird experiment at Lego. 2001-2003, Pohatu had that awkward upside-down body (and the Nuva version just looked silly). 2006-2008, we decided grey and orange was the new color of stone (though Hewkii remains my favorite set to this day). Thankfully, Gen 2 Pohatu looks great, with this 2016 model looking pretty spectacular with his new weapon (though I'll miss the boomerangs).
