Here, it is demonstrated that the unconventional anomalous Hall effect (AHE) in Cr<jats:sub>2<\/jats:sub>Te<jats:sub>3<\/jats:sub>, characterized by additional humps and dips near the coercive field in AHE hysteresis, originates from an intrinsic mechanism dictated by the self\u2010intercalation. This mechanism is distinctly different from previously proposed mechanisms such as topological Hall effect, or two\u2010channel AHE arising from spatial inhomogeneities. Crucially, multiple Weyl\u2010like nodes emerge in the electronic band structure due to strong spin\u2010orbit coupling, whose positions relative to the Fermi level is sensitively modulated by the canting angles of the self\u2010intercalated Cr cations. These nodes contribute strongly to the Berry curvature and AHE conductivity.\u00a0This component competes with the contribution from bands that are less affected by the self\u2010intercalation, resulting in a sign change in AHE with temperature and the emergence of additional humps and dips. The findings provide compelling evidence for the intrinsic origin of the unconventional AHE in Cr<jats:sub>2<\/jats:sub>Te<jats:sub>3<\/jats:sub>\u00a0and further establish self\u2010intercalation as
