Onua (voiced by Scott McNeil) is the most quiet of the group and the strongest. He is the Spirit of Earth, sportting in black and dark grey armor. He sees well in the dark, and wears The Great Mask of Strength. This masks gives the user super strength, of coarse.
He is very wise, friendly, and always ready to improve his strength. He is very well respected by his Toa brothers and sisters, espescially Pohatu. When their heavy lifting needed, He the guy to call.
- Onua has a personal negative felling towards Hades's Titan, The Earth Titan, and wants to see if can show him a really powerful bulldozer.
