Mystical Dancing Rayquaza

The Mystical Dancing Rayquaza is a enigmatic dragon of immense power that resides in a dimension of its own, and can be summoned by sufficiently skilled individuals.

Description
The Mystical Dancing Rayquaza resembles a childlike drawing of the Pokémon Rayquaza, and tends to behave in strange and unpredictable ways, possessing a tendency to wriggle, teleport, and flicker as if dancing. It is unknown where this creature originated or what its motives are, although the magical effects it carries with itself are harmless despite being severely irritating and frightening.

Powers and abilities
The Mystical Dancing Rayquaza is capable of traveling to and from any dimension and location on its own mysterious power, and has the ability to fly. When it appears, it exerts an automatic influence on everything within a wide range, which causes victims to temporarily exhibit several strange symptoms. These include the spontaneous replacement of their facial features with a childish drawing of eyes and a joyful mouth, and a completely uncontrollable and irresistible urge to dance. As this incapacitates most would-be enemies, the Mystical Dancing Rayquaza usually does not require any need to defend itself, although it has shown the ability to shrug off damage from other beings that manage to resist its power.
