I rebuilt every Vahki except for the green one! The one problem is that the black one wields a spare pair of the blue one's weapons, but that doesn't matter to me! Surrender or run!
I memorized the names of the main Toa teams, the stories of each year, each Toa in said teams, each enemy team they had to face and the names of their members, and the names of most masks. Oddly without ever really trying to.
And here I thought I was clueless on Vahki and Visorak!
I memorized almost all of that (I'm rusty on every villain team except for 2006 and beyond) and I know the names of the classic Toa Mata/Nuva masks.Heck, I probably have the Toa Metru down too.
