Jason Kurk is a recurring character in Lynchburg Heroes. He is known as the superhero '''Leviathan''' and is ranked B-10 on the official Heroes Ranking List.

Leviathan is Heroic & Justice-Driven as he takes his heroic duties pretty seriously when protecting civilians from being harmed by other villains, as seen when he was in a battle against the Crab King. He is also very confident in himself, and also acknowledges his current standings but is eager to prove himself even more. He sometimes shows a sense of humor when someone questions his hero name, replying mostly to "I just like it" most of the time. He also is very tactical and composed usually thinking ahead of time to ensure that villains/criminals are properly dealt with. He shows a responsible and strategic mindset, proving he's not about flashing his electricity or plasma around.

His voice should be able to match similarly to Andrew Russell's portrayal of Luka from the Miraculous series.
