Although most large water pokemon in Hoenn are prized by Team Aqua as shock troops, Crawdaunt were initially seen as an invasive species, having replaced the indigenous Kingler after being introduced from afar. Fact turned to myth, "across the sea" became "from the sea of stars" and the yellow pentagram on its forehead became identified with its celestial home. And in an era where falling stars meant wishes from Jirachi, the belief spread like wildfire that holding the star of a Crawdaunt would make someone impervious to wounds; the propensity of Crawdaunt themselves to be wounded in battle made little difference against the power of an insane hope.
The first time people carried Crawdaunt stars into battle, it ended in disaster; the fighters were reduced to slamming their heavy stars onto their enemy's shields in fury because they were doing nothing to make them invincible. Yet the believers in the power of the Crawdaunt star were undaunted, raised a new generation of Crawdaunt in the hopes that their stars would protect them, and weakened their furor while maintaining the inexplicable conviction that Crawdaunt's stars had some magical power to defend their users.
At one point, all that remained of this belief was a defensive style using these stars to block attacks in the manner of the Crawdaunt themselves. It promised invincibility if truly mastered, but could always blame a lack of mastery for the fact that it was never achieved. Yet in time, the pupils of this style noticed that, although not invincible, many Crawdaunt did not take extra damage no matter how well-timed or hard an attack connected with their body.
The way in which the people and pokemon of the Crawdaunt Star fighting style avoid critical hits has not been copied by outsiders to this day
