Basically the enemy counterpart of Maglev Cat, Awakened Bahamut or Sanada Yukimura, Brollow flies at extreme speeds, has low health, and deals high damage that can easily break through your defenses in numbers.
DO YOU EVEN LIFT??? He's gluten-free, but never misses a chance to impress chicks with crumbs from the organic bakery. Brain the size of a cashew, but he's got game.
Their high knockback count and low health makes them more deadly, as a few hits from meatshields like Mohawk Cat and Manic Mohawk Cat can easily knock them back. Take note that they don't have an actual attack cooldown, they only have delayed attacks due to their backswing. Thus, the more they get knocked back, the more damage they cause to your defenses.
Avoid using the default Cat Cannon against Brollows, as it will cause them to all attack again (think of Awakened Bahamut or Yukimura being hit after they land a blow). High numbers of hits per second is very bad against them, but powerful single blows from semi-spammable, bulky and heavy-hitting cats like Jamiera Cat, Island Cat and Crazed Whale Cat work well against small flocks of Brollows. However, for large flocks of Brollows, more expensive Area Attackers will be required, such as Ururun Cat.
Incidentally, D'artanyan's blind spot does not include Brollows, who will rest at the 150 mark instead of 140. This means that, in theory, a D'artanyan can obliterate Brollows, though it is better to have meatshields take hits instead of D'artanyan.
Kotatsu Cat, Kai or Sodom can help a lot as walls to gather many Brollows in the same area to kill them all at once.
Time between attacks
150 (Area Attack)
*In each stage, there is strength magnification, the value of health and attack power varies due to this value.
*Time between attacks is the time of the attack from the motion end until the next attack motion starts.
Brollow is one of the fastest enemies in the game, second to only Assassin Bear.
Brollow takes inspiration from several different birds:
He is mainly based off of the swallow, a type of bird well known for its black coat and v-shaped tail. Swallows are also a symbol of good luck, fidelity in marriage and fertility in Japanese culture.
He closely resembles a gannet, known to be the "missile bird".
He is additionally based off of the common swift, the world's fastest bird in horizontal flight, which can be clearly seen as Brollow moves forward. It also has a shorter, smaller v-shaped tail, though it is still noticeable. Another similarity between Brollow and the swift: the wings are slightly more forward on the body than they are on a swallow.
