The propagation of solitons is studied in a tokamak plasma composed of immobile ions, hot fluid positrons and two-electron sets in hot and cold temperatures with a q-non-extensive distribution. Korteweg–de-Vries (KdV) equation is obtained via the reductive perturbation method (RPM). The dependence of positron-acoustic solitons on the ratio of hot/cold electron density to positron density, positron temperature to temperature of hot/cold electrons, the non-extensivity parameters q$_{eh}$ and q$_{ec}$, as well as the angle between the magnetic field and wave propagation are investigated.
