Comic 4: A Cold Light Dawns

"Two evil Piraka, Thok and Hakann, have stolen the awesome powers of Brutaka and are on a rampage. The other Piraka have already fallen before their might. Now the Toa Inika are ready to join the battle, but they will be lucky just to survive the encounter. And if the Toa lose, Voya Nui and the universe beyond it will be ripe for conquest. By the way--that's the good news."

- Narration

Comic 4: A Cold Light Dawns was the fourth issue in the relaunched BIONICLE comic series, and the fourth in the Ignition sub-series. It was originally released with the September/October 2006 edition of the LEGO Club Magazine, and was later collected in BIONICLE 5: The Battle of Voya Nui. This comic saw the Toa Inika and Piraka fight against an power-enhanced Hakann and Thok.

Opening
''The first battle between the Toa Inika and the Piraka looked like it would end in a Toa victory. That is, until two of the Piraka--Hakann and Thok--stole the power of Brutaka and became an even greater menace than before.''

''The news gets even worse. Both the Toa and the Pirkaa now know the location of the hidden Mask of Life. Whichever group finds it first will control the destiny of the universe itself...''

The race for the Mask of Life has begun!

Plot
The Toa Inika battle Hakann and Thok, whose powers have been increased by stealing Brutaka's power with a Zamor Sphere. Hewkii fires a Zamor that Axonn gave him, as the two Piraka unleash their powers on the Toa. The blast knocks the Inika unconscious, but the Zamor caused Hakann and Thok's power to return to Brutaka.

Later, the Toa wake up, and discover the Piraka have found the entrance to the Chamber of Life. In the Chamber, Vezon waits for the Piraka's arrival. He tells Fenrakk of how Hakann accidentally used the Spear of Fusion on Vezok in reverse, splitting him and creating Vezon. Vezon then talks about sneaking away from the other Piraka and heading to Voya Nui to find the Mask of Life. He tells the Fenrakk how he touched the Ignika, and wound up fused to it.

Meanwhile, the Toa Inika are descending down the stairs to the chamber, and encounter Umbra, one of the Ignika's guardians. Umbra transforms into a beam of Light and attacks the six Toa. Nuparu uses his Kadin to fly into the air, and Umbra follows him. Matoro then creates a mirror out of Ice, and Umbra (in light form) bounces off it, shooting across the chamber until he crashes.

The Toa Inika reach the Lava Chamber Gate, where the Piraka have already passed. Nuparu creates an earthquake that stops the Piraka, but weakens the bridge as well. The Toa Inika attack the Piraka, and Kongu creates a powerful gust of wind that causes the bridge to collapse. After seeing no sign of the Toa Inika, the Piraka continue towards the Ignika.
