Larvie, both the character and the drawing too looks similar to Pikachu. At least his head. And the drawing is similar to the character.
Infurnal looks like a fox on the drawing, but based on his character description he is a wolf.
By the way, other Holozing characters also looks similar to Pokémons. At least they remind me to them.
Yes, the similarities with Pokémons are striking and I honestly used the picture I had of Infurnal and Larvie with just little manipulation to arrive at this. I guess that's why the facial expression is not definite, because of the improvisation.
I am glad you like this drawing.
