Doom Viper

Doom Vipers were six headed snake-like Rahi. They had toxic breath that could kill any forms of life, with the exception of others of their kind. They got into Ga-Metru once by way of a merchant ship that arrived from a distant land. Due to the toxic breath, only mechanical beings like Vahki have had much sucess against them.

The Visorak had little sucess capturing them as their venom weakens the webbing, so the Visorak trapped them in enclosed places and sealed them. Sometimes other Rahi unearthed these tombs to find the doom Viper alive. The same cannot be said for the Rahi rescuer.

On their return to Metru Nui, the Toa Nuva defeated several Doom Vipers by using the Kakama Nuva to confuse them and defeat them. Most of the Doom Vipers were locked in Status Tubes in the Archives.

One specimen tried to kill the Voya Nui Resistance Team, but was stopped by Brutaka, who created a vortex with his Kanohi Olmak that trapped it and teleported it over a volcano. The Doom Viper was created by Makuta Chirox.
