Ehlek

"We have a little problem reaching the mask - actually, a 300-foot long problem."

- Ehlek

Ehlek was the most anxious of the Barraki, partially because he had to use an elaborate breath mask when operating on land and that made him vulnerable. He also believed the League was betrayed to the Brotherhood of Makuta all those centuries ago, and Pridak was the prime suspect as a former Brotherhood lieutenant. In his original army, Ehlek had noticably more members of his own race than the other Barraki had of their respective races.

BIONICLE.com Description
"Ehlek was the only ass of the original Barraki alliance who was a native water-breather, from the liquid protodermis sea around the island of Zakaz. After the Great Cataclysm and escape from the Pit, he built a fortress for the Barraki, which was destroyed when Mahri Nui landed on top of it. Ehlek is angry, bitter, and hungry for revenge, almost willing to sacrifice the Mask of Life if it would mean exterminating all Matoran. Although slim and poorly armored, the spines on his back give off electric bolts that can stun or kill. He commands an army of Venom Eels."

Powers and Tools
After Ehlek was mutated, he gained rows of spines on his back. These spines could give off a powerful electrical blast that could both stun and kill.

In addition to the electricity from his spines, Ehlek's weapons included a Squid Launcher and Protosteel Tri-Talons strong enough to shred virtualy anything.

Army
Ehlek's undersea army was made up by hundreds of thousands of Venom Eels. He also had Nocturn as a lieutenant who, by extention, had some command over the eels

Trivia

 * Like all of the Barraki, Ehlek was based off of a true sea creature. Ehlek was based off of a electric eel.
 * The name of Ehlek is a play on for "elec-tric".
 * Nocturn was in Ehlek's army as a lieutenant, when he was in a good mood.
 * An interesting sidenote is that the Dark Hunters Amphibax was originally a member of Ehlek's army prior to Ehlek's exile to The Pit.
 * Another interesting fact is that Ehlek's species was tampered with by the Order of Mata Nui in an attempt to engineer a race specially designed to combat the Brotherhood of Makuta. Along with the tampering, the Order of Mata Nui gave weapons to the race, which include Ehlek's Protosteel Tri-talons.
 * Ehlek's Tri-Talons were in fact a part of his anatomy, due to being tampered by the OoMN.
