Professor Z is the founder of the Z-Men. He was born with fabulous powers of the mind, which enables him to perform all manner of nifty tricks, but the most prominent is that which enables him to read the thoughts you don't have!
This is somewhat like reading between the lines, but far more interesting.
Guard those non-thoughts well, normals! The Professor knows what you aren't thinking!

This is the 5th time the Prof has been raised to serve in the #1 jersey. Let's hope he can go on to exceed the record set by incarnation 3 (23 games, Guard and MB)
