Magby has a red body, with a yellow, flame-shaped marking on its stomach, a single spike on its back and stubby arms, and a short red tail. Magby's head is covered with large lumps that resemble hair. Like its evolutions, Magby has a black, metal shackle on its neck.
Magby can breathe out 1100-degree Fahrenheit flames, and hot embers drip from its mouth. It is also able to shoot Smog from its mouth.
A Magby's health is determined by the flames that it spews from its mouth. Yellow flames show that a Magby is in good health while a Magby that is spewing flames that are mixed with a lot of smoke show that it is fatigued. However, Magby is able to intentionally expel such obscuring smoke as to lower the accuracy of the opponent.
Magby normally live in volcanic craters. However, there have been rare occasions of Magby being seen living in towns.
