Gremlin
Gremlins, also known as Cloud gremlins are a race of Humanoid monsters found in Equestria. They have wondrous powers over weather itself, to a much greater control than Pegasus ever wish they could. However, their powers come from melancholy and sadness, rather than joy and happiness.
Biology
Appearance
Gremlins are relatively tiny creatures who vaguely resemble humans and other primate species. They tend to have red, scaly skin with elf-life pointed ears and edged eyes. They have sharp teeth, claws and small wings that allow them to fly.
Abilities
Gremlins can control the weather and fly. They're also quite good fighters, with Big Boy outmatching Rainbow Dash in aerial combat.
Behavior
Despite their brutish appearances, Gremlins tend to speak in fanciful, articulate ways, using big words such as "ruination" and "melancholy". They are however, very violent and cruel beings who enjoy causing pain to others en mass. They're not very brave, however, and the moment their enemies get the advantage over them, they tend to flee.
