Or is there on sheet I can use for lone wolf? It depends, are you talking about the d20-based Lone Wolf RPG from 2004? You might be able to use the D&D 3.5E or other d20 based character sheet, but no idea how close it is to them. If it's some other system, try look up on the internet if the core ruleset is related to some other game or is a derivative of an existing rpg, and then check if any of those games have sheets on Roll20. Is there a way to add character sheets for the lone wolf RPG?
