Pluto

Pluto is one of the many characters in Head Soccer that doesn't represent a country, like Cyborg, Kepler 22B, Devil, Valentine, Super Saiyan, Z, AsuraandMon-K. He is a reference to the popular anime series called 'Attack on Titan'. He's a 5-stars opponent that requires 20,000 points to be spent to play against him in Arcade. (Do not think it's that hard to unlock him, it takes time and just points. Just do all the requirements one by one if too hard.)

Power Shot
His Power Shot's name is unknown, though fans call it "Titan Shot". When he activates his Power, he'll suddenly spin around with blades briefly, causing him to drop any hat he's wearing. He transforms into a member of the Survey Corps (as seen by his spinning blades, green cape and 3D manoeuvre gear). When he uses the Power Shot in the air, a giant monster (fans of Attack on Titan would refer to it as the titan Annie) lit in flame appears. About 3 seconds later, it'll charge towards the opponent's goal. The ball is located in his arm, which is hard to reach if you haven't maxed out your jumping stats. If the opponent touches the ball, he'll be flung offscreen briefly. This allows Pluto to get a goal. His ground power shot is similar, though the ball is located at the monster's lower body, and if the opponent touches it, the monster will eat the opponent, which will appear after about 1.5 seconds from the air, not giving much time for Pluto to score.

Unlock Requirements
To get Pluto, you must get 9 Achievements from defeating him in the arcade or you must pay him for 4,600,000 points. The requirement is hard, because you'll have to pay 20,000 points to simply play against him. The best characters to get the Achievements are: Austria, (for the not conceding a goal) Italy, (5 Counter Attacks) and Thailand (jump.)
