To reconcile the observed unusual high luminosity of periodic source M82X-2 of the first NuSTAR ultraluminous X-ray pulsations with the most extreme violation of the Eddington limit, and in view that a persistent X-ray radiation from M82X-2 ultimately precludes the possibility of typical pulsars, we tackle the problem by the implications of "microscopic theory of black hole", the preceding developments of which are of vital interest for the physics of ultra-high energy (UHE) cosmic-rays. Replacing a central singularity by the infrastructures inside event horizon, subject to certain rules, MTBH explains the origin of ZeV-neutrinos which are of vital interest for the source of UHE- particles. Withal, M82X-2 is assumed to be a spinning intermediate mass black hole resided in final stage of growth. Then the thermal blackbody X-ray emission, arisen due to the rotational kinetic energy of black hole, escapes from event horizon through the vista to outside world that detected as ultraluminous X-ray pulsations. The M82X-2 indeed releases $99.59\%$ of its pulsed radiative energy predominantly in the X-ray bandpass $0.3-30$ keV, while the pulsed radiation over the band $0.3-3$ keV was not detected yet because it is seemingly suppressed by more powerful persistent radiation over this band. We derive a pulse profile and give a quantitative account of energetics and orbital parameters of the semi-detached X-ray binary containing a primary accretor M82X-2 of inferred mass $M\simeq 138.5-226\,M_{\odot}$ and secondary massive, $M_{2}> 48.3- 64.9\,M_{\odot}$, O/B-type donor star with radius of $R> 22.1- 25.7\,R_{\odot}$, respectively.
