Can, and under which conditions, the 125-\gev SM-like scalar with the signalstrengths for its decays into $W^{+}W^{-}$, $ZZ$, $\gamma \gamma$, $b \bar{b}$and $\tau \bar{\tau}$ being consistent with experiments be accommodated inmodels that go beyond the Standard Model? Is it truly what it appears to be,namely the SM Higgs boson, or could it be quite different? A minimal extensionof the original electroweak-scale right-handed neutrino model, in whichright-handed neutrinos naturally obtain electroweak-scale masses, shows ascalar spectrum which includes either the 125-\gev SM-like scalar or a scalarwhich is quite {\em unlike} that of the Standard Model, both of whichpossessing signal strengths compatible with experiment. In other words, the125-\gev scalar could be an {\em impostor}.
