    According to Wikipedia, a Dyon is a particle with both electric and magnetic (monopole) charges, so a Dyonic black hole would be a black hole with both electric and magnetic charges.

    If you're interested, you can obtain the metric for such a black hole by simply replacing the Q^2 term in the standard reissner-nordstrom metric with a Q^2+M^2, where M is the new magnetic monopole charge. See, for example, http://en.wikipedia.org/wiki/Reissner–Nordström_metric .
