  We prove from suitable large cardinal hypotheses that the least weakly
compact cardinal can be unfoldable, weakly measurable and even nearly
$\theta$-supercompact, for any desired $\theta$. In addition, we prove several
global results showing how the entire class of weakly compact cardinals, a
proper class, can be made to coincide with the class of unfoldable cardinals,
with the class of weakly measurable cardinals or with the class of nearly
$\theta_\kappa$-supercompact cardinals $\kappa$, for nearly any desired
function $\kappa\mapsto\theta_\kappa$. These results answer several questions
that had been open in the literature and extend to these large cardinals the
identity-crises phenomenon, first identified by Magidor with the strongly
compact cardinals.
