Karel is noted for his bloodlust that drives him to seek out worthy foes to test his mettle. He pays little mind to those who are deemed inferior in skill, but has acknowledged several individuals if they show potential of gaining his future attention. While he craves a good fight, he does not indiscriminately attack people and has held back on his cravings as he prefers to fight his opponents in the right circumstances. Cold and brutal but does not kill those weaker than himself.
