Mike is a full rigged character, free and ready to use! To enable the IK-FK functions and the bone picker, the two addons that are packed must be installed. Otherwise you can use it without these functions. More instructions in the blend file. Rigged with the Auto-Rig Pro addon.
NOTE: the "rig_tools.zip" addon must be downloaded from here: http://www.lucky3d.fr/auto-rig-pro/mike.zip
