Gruff

Gruff, better known as the NeverBeast, is a mystical beast that awakens every 1000 years to protect Pixie Hollow (and - by extension - the rest of Neverland) from the storm brought by the Green Comet.

Appearance
Gruff's appearance bears a close resemblance to opossums and certain species of dog, with white and grey fur with black swirl patterns across it. He has a opossum tail which he can use to handle small objects. His eyes are a single shade of green, which glow when the green lighting is active, and become a dull-violet when he's drugged with Nightshade. He is shown to be able to stick his tongue out similar to a lizard.

His maw contains more then one set of teeth strong enough for him to carry rocks. According to Fawn, Gruff appears to be a hybrid of Didelphis marsupialis and Bison occidentalis, which are the scientific nomenclatures for the common opossum and an extinct species of bison.

When the storm hits, he begins a metamorphosis, growing two large bison horns and a pair of dragon wings, both of which going away when he dispels the storm.

Personality
At first, Gruff behaves like a common animal, going about his own business without giving attention to Fawn. He seems obsessed by his mission, created towers from rock and pre-chewed plants when the storms hit.

Overtime however, he begins to show a more playful side, and even grows a special attachment

Powers and Abilities
Gruff is a mythical beast that is a part of Neverland's ecosystem. It is shown that Gruff is immortal, as he awakens from hibernation every 1000 years.

When awake, he does not seem to need food or sleep, being able to build towers overnight and leaving to make a new one.

When he reaches his metamorphosis, he is granted the ability to fly, and can conduct all of the lightening from the green storm, dispelling it with no ill effect.
