The first ever version of the character that is above the "half decent" line
Eldest son of Lord Kihanu and Lady Thrae, and by that same
token, rightful Lord of the House of Kihanu. Due to his noble bloodline, he is the leader of the Toa Vihagu. Despite this, even after being entitled with Lordship even before his father's death, he does not consider himself more worthy than those who fight alongside him or for him.
Zerkah is incredibly passionate about his duty, both as a Toa and as a noble. He has seen firsthand what the Malevolent have done to Talis, the place where he was born, and seeks to eradicate the Malevolent from every land he can set foot on. As such, he shows great strength and violence when in battle with the Malevolent, but great sympathy for those who are enslaved to the Malevolent's will.
Zerkah is known to become great friends with any who share
his desire for the liberation of the islands. However, this overriding desire causes him to often overlook the interests or abilities of those not in tandem with his interests. This can prove troublesome when dealing with teammates - supposedly under his command - that are seeking out their personal interests.
One would expect Zerkah would equip himself with an adorned
weapon and expensive, ornate armor, as he had the fortune to do. But instead, Zerkah choose to use his fortune to import some of the ancient but well made Jainad armor, while equipping himself in battle with a common axe. His great strength and elemental potency allow him to use even poorly made axes to deadly effect.
Zerkah underwent a pretty intense process of going from
this to the one you see before you. The whole design started from the Skull armor/HF chestplate concept and went from there.
