  Several extensions of the Standard Model require the burden of electroweak
symmetry breaking to be shared by multiple states or sectors. This leads to the
possibility of the top quark interacting with a scalar more strongly than it
does with the Standard Model Higgs boson. In top-quark condensation this
possibility is natural. We also discuss how this might be realized in
supersymmetric theories. The properties of a strongly coupled Higgs boson in
top-quark condensation and supersymmetry are described. We comment on the
difficulties of seeing such a state at the Tevatron and LEPII, and study the
dramatic signatures it could produce at the LHC. The four top quark signature
is especially useful in the search for a strongly coupled Higgs boson. We also
calculate the rates of the more conventional Higgs boson signatures at the LHC,
including the two photon and four lepton signals, and compare them to
expectations in the Standard Model.
