Korgot's Earth-Type

Easily the strongest out of the Mechs, the Earth-Type, Onua, is an unstoppable force. Despite being the shortest out of the bunch, it can hold its own in any battle. The height doesn't bother Korgot at all, considering it's also much easier for her to maneuver the mech in the subterranean Earth region. Onua's powerful claws are excellent at shoveling large portions of earth to create new tunnels as well.
However, it seems that the Earth-Type is an older model and possesses a more antiquated power source. This combined with its sheer bulk makes the mech fairly slow. It also takes quite a bit of mental strain for Korgot to pilot it, often making others consider the mech "drowsy."

Second of the bunch, first being Pohatu. I guess I'm going through with this and making all of the Toa into mechs. Onua was mostly inspired by heavy-duty construction equipment, so big pistons and blocky proportions. Initially he was going to have excavator buckets for his claws, but I decided to give him individual digits. Still not sure if I like all the gold on his legs, though... Hm.
