"I may have gotten smaller, Toa, but my power still stands greater than anything else in this universe!"
Age: Somewhere between 4 and 5 billion years old
Elemental Powers: Fire, Ice, Water, Air, Earth, Stone and Shadow.
Likes: The extent of his power
Even though Kalkan has been shortened, he is nothing less of what he was. A powerful, ruthless, god like creature. He is about three heads taller than a Toa. He has six wings, three on each side. It has been discovered that Kalkan can gain new powers by absorbing their elemental power, but killing them. A bit like Sylar in Heroes. But he also can absorb some of their power, but it will run out.
The article on Custom Boionicle Wiki says this:
"Kalkan is the Lord of the Chaos Shadow- a god like creature said to have powers greater than anything- more than the combined imagination of us 6.8 billion humans. If so, such a creature could not be contained anywhere, not the heavens, or the depths. Kalkan is rumored to be Demon King Santorakh- it is unknown if it is. If Kalkan ever stepped into Karzha Nui, the sky would go dark red, there would be an ominous eclipse, and then the Apocalypse would begin to ravage the universe..."
In fact, Kalkan is the Apocalypse. Kalkan is actually a being that lives in a rip in the universe, called 'The Chasm'. Kalkan has thought to be a tentacle like being a sixth of the universe. The 'red skies' would be a tentacle. The ravage of the universe would be Kalkan's power - death.
A updated version. V 2.01 if you like:
The 'Gauntlets' - Kalkan's hands are razor sharp, and has wrist blades.
The Pauldrons - Kalkan's demonic pauldrons are huge and broad.
The Chest - Kalkan's power chamber. Note that his chest is hollow.
Although Kalkan has been shortened, he still possesses a great height. This is him to Toa Gorahl.
It is also been known for Kalkan to be a poet:
"To be, or not to be...that is the question. But for you...not to be."
