Floyd Leech is an unpredictable man with many mood swings. When he's in a good mood, he is able to achieve full marks. When he is in a bad mood, he'll mouth off to anyone in NRC that annoys him. Including teachers. He hates restraint, and will often do things that he's told not to do. Just because he can and it's fun. He's also a merman, although he takes a potion to give himself a human form.
