Kingdom Hearts III
While Sora, Donald, and Goofy are exploring an underwater cave system in search of a new ship, Sora spots a treasure chest at the bottom of an open area, with two glowing pieces of "kelp" next to it. Despite Donald's skepticism, Sora tries opening it with the Keyblade, alerting the Lightning Angler that prey has arrived. It springs up and swallows Sora, but immediately spits him out due to the Keyblade hurting it.
Upon its defeat, it crashes into the wall of the chamber, revealing a new path forward into the cavern.
The Lightning Angler is an electric Heartless with the appearance of an Anglerfish. It is blue, has electricity patterns spread across its body, and whiskers with lightning bolts at the end. Along with that, at the end of its tail it has what resembles a pirate ship's wheel and other pirate accessories such as hooks and anchors in the design. The aquatic Heartless has blue, spike-esque teeth with a Heartless emblem on the head.
