According to a legend told in Monster Rancher 1, some Gali are actually Magic monsters hiding their true forms, but recent research would seem to indicate that the Gali are actually etherial entities of colossal size and Dragon-like appearance, so large that the cape and mask are like a puppet to it. They can project huge limbs made of solid light for punching and kicking, and can use their mask as a boomerang. Their attacks are mostly intelligence-based, taking the form of fire, wind and lightning. Gali are often defined in battle by their Power and Intelligence stats, which gain huge boosts from a very early age, and both can reach a maximum quite easily. However, Gali's strength is offset by its poor Speed, and it is relatively difficult to raise its Life and Defense stats. Gali is further hindered by having one of the shortest lifespans of any monster.
Different design patterns can be found on the capes of different Gali sub-breeds (in addition to the obvious variation in color and mask designs). The design pattern is usually a stylized Aztec weaving of the sub-breed. For example, Pixel (Gali/Pixie) sports the design of two Pixies, with pointed tails and wings.
The Gali is also know for its high-collared cape worn in ancient time to display the protection provided by a high religious authority. Because of this and the sun shape of the mask, the Gali is a general symbol of divinity with multitudes of cultural influences. Using Gali sub-breed will usually give the primary monsters this trait and as a result, the monsters often appear "holy" or "angelic". Gali as a sub-breed often provides a boost in intelligence as well.
Although Gali's appearance is similar to the Joker monsters, it is only glancing—they are inclined towards virtue and good, whereas the Joker is pure evil.
