Spinax

"Spinax here is supposed to be able to track a protodite across a planet, so finding one well-armed lunatic shouldn't be a problem."

- Matoro, BIONICLE Legends 8: Downfall

Spinax was a male Energy Hound owned by Hydraxon.

Early Life
Spinax was used by Hydraxon to help train the Toa Mata, and once used him to chase the Toa Mata separately across the island of Daxia. The Toa Mata of Ice, Kopaka, was the first one to escape Spinax, which he did by freezing the Energy Hound into a block of ice. After Kopaka, the other Toa Mata had their own unique ways to escape Spinax.

Sometime after the training, Hydraxon gave Spinax to one of the Order's Maxilos robots.

The Pit
Subsequent to the Great Cataclysm, Spinax was mutated by the Pit Mutagen, and become amphibious.

When Hydraxon learned that Makuta Teridax had possessed the Maxilos to which Spinax belonged, he regained control of the Energy Hound and ordered him to attack Teridax with the command "Manas Zya."

Spinax later assisted Hydraxon in re-capturing the escaped prisoners of the Pit, and the pair were known to have apprehended Kalmah, Ehlek, Nocturn, Mantax, and Pridak.

When the Great Spirit Robot was destroyed in the Battle of Bara Magna, Spinax migrated onto the newly-reformed planet of Spherus Magna, where his mutations were reversed by Mata Nui.

Abilities and Traits
Like all Energy Hounds, Spinax possessed the ability to track a being or object's energy signature from any location in the universe. He was also trained to obey Hydraxon's commands, and was completely loyal to his master.
