Lennart is a handsome young man with blue eyes and blonde hair. When using his powers, his eyes glow yellow As the strongest hunter in Germany with a world ranking of 12th, Lennart is heavily implied to outclass every other foreign hunter (aside from the National Level Hunters) introduced before him in the series. As a testament to this, he was able to sense the presence of the massive army of shadows concealed inside Sung Jinwoo's shadow, something not even Goto Ryuji was able to do.
