Harry Potter, during the Second Task, tried to persuade him into borrowing his spear, but he refused, laughing as he yanked the spear back from Harry. It is unknown if he was ever present at Dumbledore's funeral.
The merman was large, rising to almost seven feet tall. He bore a choker of shark fangs around his neck and had a long green beard.
Personality and Traits
Despite he was unhelpful to Harry Potter when he tried to have access to his spear, he was loyal, obeying the orders to not aid any of the champions during the task.
