Kepler 22B

Keppler 22B is an alien in Head Soccer that can use power shots of the characters before him. He's also one of the characters that don't resemble a country. To unlock him, you must beat him once in the tournament finals (he appears randomly in a UFO above the field. When the ball touches the UFO, it will crash land and the alien is the opponent.) It's a moderate unlock requirement, since it's not too hard or not too easy to unlock him. He's a 5-star opponent in arcade.

Power Shot
Kepler 22B doesn't have a specific power shot, since he uses power shots of characters before him in the arcade. This can be both good and bad since he might use either good powers or bad ones.
