These Birds (also referred to as Vultures or Monsters) are a species of unspecified magical bird that appear in My Little Universe II, as the main antagonist in the episode "Here Comes a Thought".
Appearance
The Birds are a mix between a Raven and a Vulture. They have scruffy black feathers all over their bodies, with a long neck and a slightly curved beak. Their exact size varies between different people depending on the "sins" they've committed, the largest one growing over the size of a building.
History
In "Here Comes a Thought", a huge flock of these birds appeared within Beach City. They first appear nearby the Barn House, seen by Padparadscha, Starlight Glimmer, Trixie, and Lars Barriga when they find one of their chicks. The rest of the flock appears within Beach City, catching the attention of the rest of the Harmony Gems. Fluttershy attempts to talk to one of them, but it tried to hex her instead, making her unable to understand them, and unable to be scared off by Spinel. The Harmony Gems decide to leave the birds alone as they weren't technically doing anything, but overtime the birds continue to stress the residence in town: attacking Connie within the movie theater, stealing food from Sadie Miller, and plaguing the Crystal Temple thanks to Pearl and Peridot's emotions driving them in. They reach a breaking point though and attack the Harmony Gems at the Sky Arena until they were forced away by Rainbow Dash's self-created tornado. The birds appear later on during the night to feed off of Connie's regret, attempting to feed off of her fear and trauma before her friends forced it away, triggering the entire flock to attack them. Unable to escape them or fight them off, Lapis Lazuli and Garnet tell them to "sit down and do nothing", making all of the birds settle down and disappear completely.
Abilities
Invisibility
The Birds are able to selectively control their visibility, making particular birds appear for particular people and invisible to other people. The more one person can see, the more sins they've committed.
Emotion-Altering
Similar to Changelings, these Birds are capable of feeding off of emotions, mostly regret and fear. As such, they are capable of slightly altering their targets emotions to feel these particular emotions by showing them visions of their past sins. Those effected by this become either highly paranoid (I.E. Peridot) or break down into tears (I.E. Connie Maheswaran and Steven Universe).
Size-Altering
Depending on the amount of sins exposed to the bird, they are capable of changing their size to a drastic degree, the largest one being the size of a building.
