Personality
Klaus is has only recently become a Frontier Brain so is claimed the easiest and weakest to beat. He's very clumsy and when you reach him, he runs into a wall so he can get to the battle in time. In the anime, he shows the same type of clumsiness, knocking Ash down while running past(similar to Barry & Bianca in previous generations).
