Honestly, this bestiary project is just some distraction in the event I get bored of drawing Pokémorphs =P

High Anxiety is an incredibily powerful lesser demon that act as Death's bodyguards.
They're rare demons who only appear when a great cataclysm is about to happen or when a person suffers extreme fear.

Death itself is formless. When people claim to have seen Death or "the Grim Reaper", they've actually seen High Anxiety.

Their true form is unknown, as they take on a form that's based on the viewer's biggest fear, which in most cases would be a form modeled similarly after the viewer's interpretation of Death.

They have incredibily potent magic, such as high tier elemental magic (Agidyne, Ziodyne, Bufudyne, Zandyne, etc.) and even insta-death magic that can wipe out the whole party if not guarded (Mamudoon).

They have high resistance to magic, but are relatively weak to physical attacks. However, if too many physical attacks are used, the chains will break, unleashing the true power of this monster, making it attack using an AoE attack that deals 9999 damage, regardless of stats, every turn (Megidolaon).

They're the strongest normal enemies of my hypothetical game.

And yes, chains. I plea story and gameplay segregation xP

Might rename it to "Terror" or something, and it still needs an actual name next to what it represents.

Pokémon meets SMT xP
The idea is that at one point, there was something called Primal Magic, which later separated into what's basically Pokémon moves, and into the banned and long lost Dark Magic, which is SMT/Demon magic.

Still conceptual, but it won't become a crossover aside from certain elements.
