The top quark is by far the heaviest known fermion [1]. In consequence,
experiment is just beginning to explore its properties, and some of them may
yet prove to be distinctly non-standard. The very size of the top quark's mass
even hints at the possibility of a special role for top in electroweak symmetry
breaking. This talk examines the top quark in the context of physics beyond the
standard model, and discusses how Run II can help elucidate the true nature of
top.Comment: 14 pages, 13 figures, talk presented at the Thinkshop on Top Quark
