Sanstaro Kujo is a result when Jotaro and Sans fuse, making an powerful force, although it does add some limitations to Sans and Jotaro together, this person is faster than you can ever imagine. Although he does get weaker the more he gets older. Jotaro is pretty much the leading part of the power due to Sans losing against Jotaro in a VS Thread. And it is also my fanboying over Jojo's Bizarre Adventure.
