  In the previous paper, we have shown the existence of magnetic monopoles in
the pure $SU(2)$ Yang--Mills theory with a gauge-invariant mass term for the
gluon field being introduced. In this paper, we extend our previous
construction of magnetic monopoles to obtain dyons with both magnetic and
electric charges. In fact, we solve under the static and spherically symmetric
ansatz the field equations of the $SU(2)$ "complementary" gauge-scalar model,
which is the $SU(2)$ Yang--Mills theory coupled to a single adjoint scalar
field whose radial degree of freedom is eliminated. We show that the novel dyon
solution can be identified with the gauge field configuration of a dyon with a
minimum magnetic charge in the massive Yang--Mills theory. Moreover, we compare
the dyon of the massive Yang--Mills theory obtained in this way with the
Julia--Zee dyon in the Georgi--Glashow gauge-Higgs scalar model and the dyonic
extension of the Wu--Yang magnetic monopole in the pure Yang--Mills theory.
Finally, we identify the novel dyon solution found in this paper with a dyon
configuration on $S^1 \times \mathbb{R}^3$ space with nontrivial holonomy and
propose to use it to understand the confinement/deconfinement phase transition
in the Yang--Mills theory at finite temperature, instead of using the dyons
constituting the Kraan--van Baal--Lee--Lu caloron.
