Max Malicious Moonsault (ハイパーダーククラッシャー改, Hyper Dark Crusher Modified) is Incineroar's Final Smash in Super Smash Bros. Ultimate.
Overview
Incineroar dropkicking Fox during Max Malicious Moonsault.
Incineroar rushes forward and grabs an opponent. If it connects, Incineroar will throw its opponent into a fighting ring and assault them with an uppercut, a dropkick and another uppercut before splashing them, causing a giant explosion. In Sakurai's own words, it's even faster and fiercer than the Z-Move it's based on. While the move can only connect on a single opponent, subjecting them to the damage from Incineroar's attacks, the fiery explosion will damage anyone caught in the blast radius after the cutscene has ended.
Origin
Incineroar using Malicious Moonsault in Pokémon Sun/Moon.
Malicious Moonsault is a Dark-type Z-Move exclusive to Incineroar, which acts as a powered-up version of Darkest Lariat. As with most other Z-moves, it has a PP of 1, though its base power is always 180, as it requires Darkest Lariat to be used.
When initiating the attack, the Incinium Z crystal will flash on the screen. This reflects how it, along with other Z-Crystals, shows on-screen in Pokémon Sun, Moon, Ultra Sun, and Ultra Moon when the Z-Move is activated.
