The Exotic Dragons are a kind of dragons that exist in Dragons: Rise of Berk. They look like the adults from their species but with different patterns and different stats. According to the game, they don't change their appearance when they reach the Titan Wing stage.
This dragon looks like any other Flightmare, but emits a faint green glow. Its underbelly is brighter, somewhat like neon green, and its wings are speckled with small white spots and vein-like patterns.
