>>28301474It's not any specific pokemon.
Type: Null is meant to look like it's cobbled together from parts of different beings which is why it has that weird fish tail and vaguely insectoid front legs of a different color but it's very distinct among other pokemon and doesn't really look like it's supposed to be a specific animal, though it almost certainly has some other form or evolution or something to that effect.
By contrast, Chimeramon is just a blend of different digimon parts, a lot of them are bigger/smaller than they should be but it doesn't have a single feature unique to itself
