Deformed W-algebras are two-parameter deformations of classical W-algebras that exhibit deep connections with quantum integrable systems. A key feature of these algebraic structures is that their fields can be understood as deformations of ordinary q-characters, naturally leading to their designation as "qq-characters". In the established theory, q-characters are inherently generated by the q-char
