Tunneler

"As the fireballs approached, it reared up on its hind legs and purposely let itself be hit. An instant later, it had transformed from a creature of scales and claws to a monster of flame."

- Narrator, Trial by Fire

Tunnelers are lizard-like Rahi.

History
The Tunneler species was created by the Makuta using Viruses and Liquid Protodermis as one of the Rahi species to inhabit the Matoran Universe.

A population of Tunnelers live in Po-Metru. They have been known to burrow into Protodermis Warehouses and consume both raw Protodermis and finished tools. Toa Metru Vakama and Onewa defeated one by making it turn into glass, a form too fragile to withstand its weight if it moved.

Abilities & Traits
Tunnelers are about twice the length of a Matoran and eat solid Protodermis. Although they do not usually pose a real threat to Matoran, occasionally one will give in to a madness and rampage through Matoran work areas. Signs of this condition include red eyes and mottled scales.

Their primary defense is their ability to take on the form of any force directed at them. This can make them very dangerous, but can also be exploited as a means of defeating them.
