Wulph is the leader of the Army of the Dragon, the crew of purple Pack-Class dragons. His name is derived from wolf, a pack-animal.
Wulph is a secondary character, not making very many appearances and when he does, viewers are usually uncertain what side he'll take. He's taken both before, and flip-flopped from side to side several times.
Wulph wears purple, matching his crew, most of the time with his insignia on his back. He has a scar over his eye, supposedly from one of the challenges at the Academy, having to compete against your own dragon. He and his dragon, Hyve, went for the same piece of White Rappel Gear, and upon contact deployed, hitting both in the face.
