Soul Calibur V
Being a ninjutsu practitioner, Koga is well known for having unpredictable and deceptive strikes. He has several acrobatic movements, tech traps, as well quick and unique kick attacks; making him quite difficult to defend against. As one of the fastest characters in the series, he can easily evade and counterattack the opponent in various ways through either somersaulting, rolling, or even teleporting up in the air. Koga's kicks are very useful and damaging - for many of which have the potential to ring an opponent out. Also, his kicks, combined with the dual kodachi, make an excellent combination for combos just as long as the player knows how to execute them properly. Her low attacks also have their advantages, for he even has the ability to drop a numerous amount of darts while the opponent is down. His throws can deal low to high damage and sometimes can be used in combos; even his aerial throws are something to watch out for. Koga also develop his own ninjutsu which he called Dokujutsu (Poison Technique) which is his unblockable attack, this poison is so deadly that if the poison hit a human skin, it'll burn, also if a living being breathe the poison they will be paralyzed for three days and die in the fourth day.
