Ryker Grimborn is a recurring antagonist in Dragons: Race to the Edge. He is older brother of Viggo Grimborn and the second-in-command of the Dragon Hunters
The physically imposing leader of the Dragon Hunters, Ryker may not share the intelligence of his younger brother, Viggo, but he more than makes up for this defiency in brute strength.
Ryker is as direct in purpose as he is in combat. The elder Grimborn cares only about wealth and will overpower any obstacle, human or dragon, in his obsession for greater riches. Solemn and brooding, Ryker seldom speaks. He simply takes what he wants, uses it to his benefit, and then discards it like a shed dragon skin.
