  We argue the conjecture that the on-shell component super particle actions
have a universal form, in which the physical fermions enter the action through
the ein-bein and the space-time derivatives of the matter fields, only. We
explicitly constructed the actions for the super particles in $D=3$ realizing
the $N=4\cdot 2^{k} \rightarrow N=2\cdot 2^k$ pattern of supersymmetry
breaking, and in $D=5$ with the $N=16$ supersymmetry broken down to the $N=8$
one. All constructed actions have indeed a universal form, confirming our
conjecture. Our construction is strictly based on the assumption that in the
system we have one half breaking of the global supersymmetry, and on the very
special choice of the superspace coordinates and component fields.
