|"Are you a wizard or not?"
|Unidentified Merman (Black Lake)|
Around 7 feet
During the Second Task, Harry Potter tried to borrow his spear to cut the ropes binding the hostages, but the merman refused, laughing as he yanked the spear back from Harry. It is unknown if he was present at Dumbledore's funeral in 1997.
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.
