- "Hammer-horned and hungry, these shark Noise are able to pound out killer tsunamis!"
- — Noise Description.
Fusion Shark is a form of Shark Noise in The World Ends with You.
- Chomp: Following up every Dive, Fusion Shark will send its head out of the water to make an attempt to bite at the player, inflicting a good amount of damage. Before every Chomp, a ripple will appear the targeted area for a second. Chomp also allows Fusion Shark to eat other smaller Noise to increase its stats. After each successful Chomp, Fusion Shark dives for a moment before its fin appears again to roam.
- Razor Fin: As it roams around, Fusion Shark's fin can inflict damage to the player if they collide.
- Dive: fusion Shark dives, becoming unable to be targeted, even by Fusion attacks. The Fusion Shark will frequently dive, always following up with a Chomp.
