Name: Onua 

Alias: Toa of Earth, Master of Earth, and Uniter of Earth. 

Gender: male

Siblings: Tahu, Gali, Lewa, Pohatu, and Kopaka. 

Appearance: 

Personality: Onua is something of a sage, preferring to spend most of his time in solitary meditation, though he sometimes dozes off while doing so. He is quiet, but is known by the other Toa to be wise and down-to-earth, so when he does speak, they take his advice seriously despite his crude voice and large stature. Onua is also known to be afraid of heights.

Powers and abilities: 

Onua possesses both night vision and the ability to control earth and create earthquakes. He currently carries a drill ended hammer. His main tools before this were a pair of Turbo Shovelers for digging. These could be converted into an Earthquake Hammer for powerful attacks.

Onua originally wore the Mask of Earth, and later, the Golden Mask of Earth. He now wears the Unity Mask of Earth and the Golden Unity Mask of Earth.

Dragon: He has Crystal Crusher name Topaz. 

That's all for Onua's bio. 

While I'm doing Ekimu's bio, if you guys have any ideas how the six Toa ended up in Berk and met Hiccup and his team, let me know at the comments below. Peace out and enjoy!
