gus i can not understand something what is spike's surename?

Spike's surname is never revealed in the series but if bạn read the comics (not seasons 6/8 but the others that fall between episodes of the series) it is revealed the his human name is William Pratt in Spike: Asylum bởi Lynch. It is not đã đưa ý kiến but in that comic his is issued a container of blood (it's a baddie rehab) and the container is labeled William 'Spike' Pratt along with his năm of siring. His birthday is not revealed though.

This is one of my yêu thích comics, truly recommend bạn picking up both this and Spike: Shadow Puppets as they read as a series

William Pratt
