Batman's cool and all but i kinda dislike the undertone that swings with your statement.
Pray:
Mastered the Mayer Style, witch is a amalgation of all Earth based Weapon - and Martial arts, ancient and modern. She learned it and took a collective shit on it, creating the Pray Style, that outdones the Mayer Style to such a degree that the Knight Order tried to persuade her into making it the main fighting style for ALL Knights. The Mayer Style was already feared throughout the universe, but compared to the Pray Style it was considered impractical and weak.
Became the greatest Knight throughout history, outdoning literally every other Knight that came before her while she was still a trainee, including
Sion Zail,
Dry Leonhard and many other great Knights. Sion was considered the greatest Sword Master in the entire History of Humanity, but she was outdone by Pray in her training times. Dry is literally Mister Perfect and was stated by even Pray to be greater than her in every aspect. Sans skill.
Talking about Dry, Dry posesses Pseudo Almighty and had a army of the most powerful Knights of the Order. The mere though of facing Pray made him shit himself. He managed to barely managed to beat a inexperienced version of Pray's prime in a duel with his ability. Note that Pray's prime means a past version of Pray 8 years ago, she further honed her abilities and is still not surpassed.
Anne, the second greatest Knight in history, had a winning record of 3% against Pray. The same Anne that steamrolled Armies of Knights, fought an entire planetary war alone and was deeply respected by Dry.
