Mato

Pumpkin Man is the unnamed announcer for the Grand Magic Games Preliminary Event.

Appereance
It's unknown if he's a pumpkin creature or a man with a costume. His head is a giant pumpkin with eyes and mouth. He wears a striped jacket with a dark cape, pants, boots, gloves and a dark witch-like hat. On the backside of his cape, there's the word "MATO" written (that could stand for a part of the word Dai Matō Enbu, "Grand Magic Games", in japanes)

Personality
He's often seen smiling and dancing, but has a bit dark personality, as he smiles when he announces that they won't take any responsibility for deaths in the labyrinth.

X791 arc
He appears as a hologram floating above Crocus, announcing the Preliminary Event and its rules. He later is seen congratulating the teams that have passed on the Preliminary Event. When the Team Fairy Tail A ask if they were the first to reach the goal, the Pumpkin Man replies that they barely make eighth. .
