We study the decay modes of a S-wave superheavy quarkonium, formed by a possible fourth-generation quark in two-Higgs-doublet models. Because of the enhancement of Yukawa couplings and longitudinal weak bosons the main decays of these superheavy states will be into neutral scalar bosons H/sub i//sup 0/H/sub j//sup 0/ and a charged scalar plus a W boson. If the H/sup minus-or-plus/W/sup +- / channel is open for the psi(1/sup --/) superheavy quarkonium it will provide a quite clean signal for a charged Higgs boson. The decay of the pseudoscalar quarkonium eta(0/sup -+/) into a Z boson and one of the scalars will also be present in a large amount.
