Battle for the Ancient CityEdit
Upon entering the Ancient City of the Mask Makers, Tahu accidentally set off a trap that sealed the Toa inside the city. Skull Warriors then emerged from the ground and more began firing from a top the wall at the Toa. Onua used his Earthquake Hammer to defeat the ones that came from the ground, but also collapsed the bridge upon which they entered. Lewa returned from scouting and knocked the Skull Warriors from the wall onto the ground, where they were easily dispatched by the other Toa.
The Protectors and Harvali later found the remains of these Skull Warriors when they too entered the city. But they were forced to engage another group. They successfully defeated them before moving on to meet Ekimu and the Toa.
Final DefeatEditLater, after the Okotans had reclaimed the city, the remaining Skull Warriors attacked, but were initially dismissed as not being much of a threat until a force of Skull Spiders teamed up with them. However, using their new masks and armour, the Toa swiftly defeated the force of enemies, before moving on to find their Elemental Creatures.
Powers and ToolsEditSkull Warriors aad the power of Elemental Absorption.
Skull Warriors were physically weak, but made up for it in large numbers. They were however accurate shooters.
