"Yawa", according to the artist, is a Cebuano/Bisaya word which literally translates to "the devil". It is used as a vulgar exclamation/curse when frustrated.
These mixed crowd illustrations with lots of series and characters are always fun. There are a few that I'm definitely missing though. Does anyone recognize the un-annotated characters here?
Managed to identify the cat as Oragon from Monster Strike. Blue thing may also be from there.
So not a cat at all then, the "ear" was a single horn.
For a franchise with "monster" in its name, and even with this Oragon seeming to serve as a mascot of sorts in the UI of their website (it shows up a lot in icons and things), the creature-like characters don't seem to have much prominence. Almost everything listed or drawn in fan-art seems to be human(oid).
If the blue thing is from this game / series, it might be hard to track down.
That's a lot of pokedex entries... I've got to admit though Quetzalcoatl + Koala = [Quetzal]Koalius is pretty clever. (At least I assume that's what they were going for based on the Aztec-looking accessories and stonework on the throne.)
There's very little beyond the color and possible ears (what I initially thought were legs) to link it to "the blue thing" here though. It really isn't drawn with any real sort of distinctive details to let us draw a strong conclusion.
