 abstract={In this work, we compiled and cross-identified optical variability data for Roma-BZCAT blazars using nine major photometric surveys. Despite the inhomogeneous nature of these datasets, their integration provides a unique opportunity to statistically characterize blazar variability and identify extreme cases for detailed study. Cross-identifications were performed between BZCAT and these nine catalogs, and variability parameters such as amplitude, periodicity, and light-curve morphology were analyzed across different blazar subtypes (BZB, BZG, BZQ, and BZU). Several objects exhibiting extreme variability were identified as candidates for detailed follow-up studies.},
