We present results from the archival Chandra observations of the 0.3 s X-raypulsar PSR J1846-0258 associated with the supernova remnant (SNR) Kes 75. Thepulsar has the highest spin-down luminosity (Edot = 8.3e36 erg/s) among all thehigh magnetic field pulsars (HBPs) and has been classified as a Crab-likepulsar despite its magnetic field (5e13 G) being above the quantum criticalfield. It is the only HBP described by a non-thermal Crab-like spectrum,powering a bright pulsar wind nebula (PWN). Our spectroscopic study showsevidence of spectral softening (photon index = 1.32 to 1.97) and temporalbrightening (unabsorbed flux = 4.3e-12 to 2.7e-11 erg/cm^2/s) of the pulsar by~6 times from 2000 to 2006. The 0.5-10 keV luminosity of the pulsar at therevised distance of 6 kpc has also increased from 1.85e34 to 1.16e35 erg/s, andthe X-ray efficiency increased from 0.2% to 1.4%. The observed X-raybrightening and softening of the pulsar suggests for the first time that thisHBP is revealing itself as a magnetar.
