This here is a new reference sheet for Edgar. This features a new colour scheme, slightly redesigned body, a corrected detail and clearer ability diagrams, and replaces the original ref: https://www.furaffinity.net/view/19501526/
The design is based off the concept created by  jouigidragon as seen here: https://www.furaffinity.net/view/27112390/

The newest edition to Edgar is a dewlap-like ring of fluff around his neck. It acts as expanding space, allowing him to shove bigger things down his maw, as well as allow him to perform a 'vacuum' ability, expanding as Edgar breaths in, allowing him to pull anything near him towards his maw.
He also has a chocolate-scented belly now. The scent can sometimes turn hypnotic, so be careful when near him

Below is the text from the original ref:
Unlike many of my characters, this one doesn't have that much of a backstory. He's an Otter, who lives by a river, and is nice and round, and is also a show-offy vore pred~

Edgar more or less prides himself on his round belly and always enjoys a very good, wiggly, meal~ When he gulps them up, any prey in his belly is shown off as a belly-tattoo/mark on his gut, something Edgar will happily keep in full view, as if he was showing off a 'trophy' collection. Not bad, right? Well, it's what comes afterwards that might worry prey. Edgar's belly can then, in lieu of digestion, 'absorb' the prey directly through his stomach lining, fusing into his soft pudge, where they're kept in a state of conciousness, aware that they're part of a fat belly. And any prey absorbed into Edgar's belly is signified by his tail rings. Upon absorption of a prey, a ring glows on his tail. Overtime, the glow will fade, and once it fades completley, the prey becomes a permanent part of the Otter's belly, forever~~

Though, considering how most vore scenarios go, forever may not actually be too long, as most perma-scenarios are often seen as non-canon. So, permanent, but maybe not too permanent? In fact, alternatively, the tail rings could be used as a timer of how long the occupant is otterpudge, with the fading simply being that they're gone/reformed, if prefered. I'm willing to be a bit flexible on this detail ^^

Anyways, if Edgar decides you're tasty, but he's not into eating right now, he has a solution for that. He'll stuff any prey-to-be down into his belly-button, making sure they're tucked tight into it. Only their feet/head stick out, wiggling as they're surrounded by their fate, at the Otter's mercy~
