Lionfish was a male SeaWing soldier who accompanied Fathom to the Night Kingdom, along with Indigo and another soldier, Wharf. He later killed Quickdeath after the assassin-for-hire attempted to assassinate Darkstalker. Like Wharf, he was described to be lazy and sleepy. He often neglected his duties as Fathom's bodyguard, sleeping with Wharf inside Fathom's quarters provided by the NightWings.
It is assumed that he went back to the Kingdom of the Sea when the NightWings evacuated, along with Wharf.
- A lionfish is a venomous type of saltwater fish.
