There are five forms of nonlinearity that are being taken into consideration. The exact 1-soliton solution of the perturbed nonlinear Klein-Gordon equation is obtained for each of these five forms of nonlinearity. The soliton ansatz method is utilized. The parameter domains are also identified. Keywords Klein-Gordon equation; 1-soliton solution; Integrability; Topological solitons
