Conner is a high tempered fellow who gets mad really easily. He would do anything to make sure his friends wouldn't die even if it leads himself to dying instead. If his friends are hurt or killed, the person responsible will not be alive for long.
He has a dragon, or what Homestuck likes to call his "lusus," which took care of him when he was little until it disappeared. Conner also likes to believe that someday he'll become a mighty dragon.
He has the Magical Powers of a Dragon with the fire.
