The resource I’m using to make human type place holder monsters is a site called Tektek.org and the Gaia Dream Avatar Creator from the web baised MMO Gaia Online. Tektek uses all avaiable items for your avatar from Gaia to make a spiffy looking little character.
Here’s the link to one of the Rookie Agents I made if you would like to make one too.
I’m going to sketch out bigger more detailed versions of these with my Wacom tablet but the look of these characters at least makes the game more playable and helps me collect my thoughts better.
To create some nice Anime style facesets for your characters when they speek I used Face Your Manga to create a Rookie Agent’s face.
