These two were drawn by Meshsmoother. He tends to draw in a more realistic american comics style,
rather than in the cute anime style, so it was a bit of a challenge for him to transform Adol.

The 2nd one, was an earlier request, to draw a character from Demons Souls based on a screenshot
from the Korean version of the game.

This was a drawn by Desfunk, who now runs a game store called The Basement.
The reason the Vault Boy has 5 fingers is that the artist felt uncomfortable just drawing 4 fingers.
