Ah, yes... A drawing I'm quite proud of. No, Blaze is not a werewolf. The wolf in the background is called a Nightmare Wolf, they are powerful and deadly wolf like creatures that roam Lost Land. Blaze was a hero who worked beside Erin in the Original Mario Universe until he was corrupted. Erin got corrupted as well, but unlike Blaze she was able to fight off the corruption which created Shadow Mario, a Mario made of pure shadow.
