"As Altered Beast's resident evil wizard, Neff is a natural for the Bad-Anon meeting roster."
Neff is a wizard that is disguised as a large, purple rhino with golden shoulder pads, shin guards, and gauntlets. As normal rhinos do, Neff has two horns on his nose (one larger than the other). Neff also has three toenails and fingernails on each of his hands and feet.
