The Flock of Fury is the name of the bird-themed Aves Family. The group's first appearance occurred in Enter the Cuervo, but their main episode appearance was in Eye Caramba!, in which they declare their revenge on the Rivera family for breaking their hearts. The Flock is also one of the few individuals that actually keeps their identity secret, thinking that if anyone knew their true identity, their family would be ruined upon.
They all have similar bird themed costume wardrobes including the trademark helmets (beak visor included), a set of jet-propelled wings, a black combat suit, boots and all of them are equipped with lasers. They do have little differences though:
Black Cuervo has a small tipped visor and raven-like wings. Her color pattern is purple and her bird theme is a raven.
Voltura has tuffs of fur on her gloves and chest with long feathery wings that are always visible unlike the other two. Her color pattern is green and her bird theme is a vulture.
Lady Gobbler has a huge collar that resembles turkey feathers and a gray dress under her black suit. She also wields a scepter/cane with a handle shaped like the head of a turkey. Her color pattern is orange and her bird theme is a turkey.
They all use some type of laser weapon but seem to have their own way of employing them:
Black Cuervo has only one laser on her wrist. Later on, she adds a second one on the other wrist, and it is scented to smell like strawberries.
Voltura has two lasers that eject from both wrists. They seem to be the biggest and most powerful of the three.
Lady Gobbler has a turkey-looking cane that transforms into a laser gun.
One of the gadgets each family member has a wrist communicator. Despite it resounding as loud as a truck backing up, they use this to generate a red-tinted hologram of each member and conjointly plot their evil schemes
All three members of the Flock of Fury has had and still (albeit in denial) have a crush on one of the Rivera men. However, all three Riveras have one way or another broke up or dumped them. Thus, they always seek vendetta (revenge) on them whenever they can. The Aves/Rivera factor seems to go in a pattern:
Voltura and White Pantera dated in high school, but broke up. Everyone except Voltura, who is still in denial, knows he broke up with her. It is not known if he broke up with her to run off with Maria Rivera, but eventually he does marry her and together they parent Manny. When someone corrects or reminds her that Pantera broke up with her, she would shout, "As if I could forget!"
Black Cuervo and El Tigre date in middle school, as seen in Tigre + Cuervo Forever, but only for information on the Flock of Fury's crimes. Previously, Cuervo had beguiled and through flirtation manipulated him to trash Frida Suárez's birthday party. As the creator Jorge stated, in a canonical future the two officially date throughout high school, but Tigre broke up with her for unknown reasons.
