I gave an idea of what I think the artist was going for with the names.
"Kentragon", if I'm not mistaken is a reference to Kentrosaurus, a member of the same family as the Stegosaurus. Could also be using "Ken" or "Kendo" (as in "sword" or "sword arts") as a portamentaeu.
"Pachyx" Pachycus from "pachiri" being an onomatopoeia for sparking. Possibly also using a similar "-yx" suffix as some early birds (like Archaeopteryx).
"Prichilldon" "Plichilldon"; the "Chill" is pretty obvious but my knowlege is lacking for the rest of the reference.
Same with "Wonos" ("uonousu"); I took a stab at how I think the katakana is supposed to be tranliterated, but I don't know enough about the creature the "Vish" head was based on to work out the reference. "Oneus" ("won-eus"); this'll teach me to actually look up the name of the creature first. :P

I don't know enough moonrunes to confidently have a crack at the rest of the text, so someone else can have a go at that.

EDIT: I spotted the "motif" bit at the bottom of the bio.
I can now confidently say I know the names of the creatures these mons were based on.
"Pachyx" is now "Pachycus", as it is now clear the name is a reference to Deinonycus.
"Prichilldon" is now "Plichilldon", as it's now clearly supposed to be an 'l' sound, not an 'r' sound.
"Wonos" is now "Oneus", to better match the name of the creature it is based on: "Dunkleosteus".
