Doom Viper

"I cannot stand by and watch something even this repulsive fall to the Visorak ... Bomonga discovered a few Stasis Tubes intact in the Archives, so I am keeping these monsters stored in them, where I hope they will stay forever."

- Rahaga Norik, Rahi Beasts

Doom Vipers are six-headed serpentine Rahi.

History
The Doom Viper species was created by Makuta Chirox using Viruses and Liquid Protodermis to be one of the Rahi to inhabit the Matoran Universe.

The Matoran of Metru Nui first discovered the Doom Vipers on a cargo ship docked in the Ga-Metru harbors. Ga-Matoran were surprised to discover that the crew was missing, though the cargo was still intact. Only later was it discovered that the crew had all been killed by Doom Vipers; by that time, the vipers had already begun making their way to the heart of Ga-Metru.

When the Toa Nuva returned to Metru Nui, they had to battle six Doom Vipers. The Nuva defeated the vipers by using their Kakama Nuva to confuse them, after which they attacked them.

Doom Vipers also live on Voya Nui and the Southern Continent. Brutaka once saved Balta, Piruk, Velika, and Kazi from one out of habit by using his Kanohi Olmak to teleport it into Mount Valmai.

==Abilities & Traits ==

Aside from its multiple heads, the Doom Viper is most notorious for its breath, which is a toxic compound that is capable of killing any living animal or plant life it touches (except other Doom Vipers). Vahki, being machines and thus immune to the venom, were the only ones successful at capturing these Rahi. Doom Viper breath is also capable of weakening Visorak webbing.
