Pretty Black Hole (プリティブラックホール Puritī Burakku Hōru) is a technique used by Zirloin, Rabanra, and Zarbuto after using Formation. It is team attack that not even the Kamikaze Fireballs were ever able to use.
"Love can be all-consuming. It can paralyze and torment us with its intensity. Yet those who master love can control its weight and unleash this mysterious, beautiful, cataclysmic attack!"
The Pretty Black Hole is created when the users create three mini pink hearts that turn black and combine to form a large black heart. The black heart then consumes the target, and pushes them into the ground with its gravitational weight, similar to an actual black hole. It is noted by Zarbuto that not even light can escape this attack, and the intensity is enough to prevent movement through space, as seen when Goku was unable to use his Instant Transmission. The inside is composed of trillions of mini black hearts.
During the Tournament of Power, Zirloin, Zarbuto, and Rabanra used this attack on Goku, Android 17, and Android 18. Once trapped, the attack pushed them further and further into the ground with the plan being to push them all the way through to the other side of the arena, and causing a ring out. Goku found he couldn't even use his Instant Transmission move to escape, so he powered up to his Super Saiyan Blue form and fired off a God Kamehameha into the attack. The attack seemed to contort several times before reaching the outer component of the heart, at which point it broke through the heart and blasted the trio out of the ring, thus eliminating Team Universe 2.
