Lebiathan 

A word used by people with mental disabilities to describe the biblical monster Leviathan.

Wow, that guy is a real Lebiathan. Also, I have AIDS.

Reaper Leviathan 

The last thing you want to meet while playing Subnautica. It's really fucking creepy and is gonna kill you. For safety reasons, reapers spawn in these biomes, so take care of yourself: The dunes (8 of them), The Mountains (6 of them), and the crash zone (7 of them) plus one in the bulb zone at the edge of the crash zome.

I was casually playing subnautica when this fucking thing so-called the reaper leviathan roared and grabbed my seamoth. Never visiting the dunes again.

Orpah the Leviathan 

Queen of the underground; one of many forms of degenerate evil loosed upon this sick world.

Legend has it that upon fierce copulation with Goro, she gave birth to Moran, father of the moleman race. As of late, has resurfaced under the guise of Oprah, a daytime talkshow host.

"Man, I just referenced Orpah the Leviathan in conversation, and NOBODY had any idea of what-the-fuck I was talking about. Not a problem though, because M. Bison flew outta nowhere and kicked them in the ear."

Leviathan 

the shut-in otaku third-born of the seven demon brothers from the game Obey Me! Shall We Date, my personal bias (next to Simeon), and the Avatar of Envy, and/or the Avatar of Being A Relatable Otaku.

i stan this man, i love him, and he is one of the few reasons i put up with the bullshit at the Royal Academy Of Diavolo.

he goes by the titles "otaku", "shut-in", "weeb", and "anime-obsessive introvert", which are the titles i go by irl sometimes.

bro probably has more posters and anime figurines of waifus than you've had chances to do your homework.

"the Hana Ruri cosplay is staying on during Comic Con, alright?!"

if he needs someone to help him play horror games at 3 AM, i'm gladly running over with Happy Meals in tow.

as you can tell, he's one of my favorites, and if he ever wants to live in the real world, i've got a spare bed ready for him and a whole disk drive of video games and anime for us to binge.

POV: Leviathan and MC at a local Comic Con:

"why don't we cosplay as Pokemon trainers-"
"NO! THE HANA RURI COSPLAY STAYS ON DURING COMIC CON!"
"okay, i'll just match and cosplay as Cardcaptor Sakura, then ^^"
