Zacku is the archnemesis of Macku. She is often described as a mean bratty snob that treats Tiki like a slave, she has a very short temper and has most recently been seen informing Dark and Newsy of the mysterious ships seen on L.L.A.M.A.S. News. She became a Toa along with Dark, Bob, Newsy, Onepu Nuva, Torri Torri, and Tiki.
