Daran

The Kanohi Daran is the Mask of Confusion. There is only one in existence, which belonged to Kakamu. It was left in inter-dimensional space when Kakamu's armour was destroyed but was later found by the Fellowship of Kakamu, who put it in the Realm of Shadows.

Kakamu managed to find a way to duplicate it, so both he and Trantoshen could have one. Confusingly, the one that Trantoshen wears is Kakamu's, and the one that Kakamu wore when he was a Turaga belonged to Trantoshen.
