To start, I’d like to reiterate what many others have already stated by saying it’s a real treat to have you here and answering questions! Your time and creative thoughts are highly valued!
My first (of a probable and eventual many) question is; Was there ever any thought on any beings in the MU existing with multiple elements outside of the Takanuva/Teridax fusion and the 2006 Toa whom were partially of the Lightning element? For instance, in the MU, could a being of Fire/Shadow or Water/Sand have existed?
If you do happen to read this or respond, I greatly appreciate your time in doing so!
(PS. Other than George Lucas and a few others, you are and have always been in my top 5 favorite writers, your work is an inspiration)
