Now, I am aware of the fact that a Beerus/Bills already exists as a mod over Lucario, but I will reiterate that this is the model from Dragon Ball Xenoverse (and personally, the model available on this site is.....kinda ugly....). So, I will include a download of anything a rigger needs to rig with. If additional materials are required, I will do my best to add them to an updated download.
Link to the items needed (will update if possible):

PS: Do remind me to move this if I posted it in the wrong location (again...).
