He has purple hair, light skin and round sunglasses that can be knocked off of him. Furthermore, he has a small nose and a grey beard. He also has stitches on his forehead that make him look a bit like the human version of Frankenstein.
Poland's Power Shot is the Ice Spike Shot. He yells out "Ice Spike... Shot!" and six large ice spikes protrude from the ground. These ice spikes, however, don't affect the opponent. Approximately in between the third and fourth spike emerging from the ground, an icicle is fired in a straight line towards the goal that contains the ball. If the defender successfully blocks the ball, he will be frozen (like Russia) and is hit straight up in the air. This gives Poland an opportunity to score without his opponent standing in the way. The opponent lands back down about 2 seconds after he is hit by the icicle, and defrosts yet another second later. When the opponent is frozen, he can't kick, jump or move, but he still can use power shot, and can be moved by getting kicked very easily.
As said, to unlock Poland, you've got to reach SS Rank in Survival with 21 characters, but because this takes a lot of time, you might need some help. Fortunately, there is a useful glitch to unlock him, but you must have at least 21 characters unlocked. Then, get at least to E rank with 21 different characters and you may have unlocked Poland. Most of the time, this has proven to work, but there is yet another way to get him. Rarely, when you finish beating the Cyborg on Stage 10 in Survival, you can hear a soft sound, that you usually hear when you have unlocked a character. It means that you have unlocked Poland, even if the game didn't show you the unlock screen. It happens seldom and we haven't figured out yet how it works.
