Sidorak was the king of the Visorak horde. In his early life, he was a minor power in a land filled with conflict. He rapidly discovered that by claiming credit for victories won by those beneath him, he could advance in the eyes of his leaders. Whenever a commander objected to the credit being stolen, Sidorak would simply dispatch him on a dangerous mission from which he would not return. This talent for treachery attracted the attention of Makuta. Makuta made Sidorak one of his lieutenants, along with Roodaka.
Sidorak was the king of the Visorak horde. His spinner power was obedience. His weapon was a herding blade. His allies were the Visorak legions. His preferred tactic was to have others fight his battles for him, or else strike foes when they were already weakened.

Sidorak's primary power was his strength. Although not as strong as Keetongu, he was far stronger than a Toa. He was an excellent strategist and tactician, having masterminded a number of Visorak campaigns. He was skilled at manipulation, so much so that it never occurred to him that he might be manipulated in turn.
Sidorak was not a king who hid in a fortress – he preferred to be out leading his Visorak into battle. Deep down, however, he knew that he had not really earned his position, which made him try that much harder to prove a successful and ruthless conqueror.
