In the World of Ryuki, Abysslasher is one of Kamen Rider Abyss' two Contract Monsters. Kamen Rider Abyss' Final Vent enables Abysslasher to combine with Abysshammer into a giant shark called Abyssodon (アビソドン Abisodon) which is when it is destroyed by Decade and Ryuki Dragreder.

Through the use of certain Advent Cards, parts of Abysslasher's body can be used by Abyss as weapons or other equipment.
- Abyss Saber (アビスセイバー Abisu Seibā): Abysslasher's bone-like pair of swords. Abyss can summon them by using his Sword Vent card.
- Abyss Claw (アビスクロー Abisu Kurō): A gauntlet capable of firing high-pressure streams of water Abyss Smash (アビススマッシュ Abisu Sumasshu) that is derived from Abysslasher's head. It is summoned with Abyss' Strike Vent card.
