They made their first appearance under the form of Yuri Alpha and Lupusregina Beta. Alongside the summoned Evil Lord Wrath and Aureole Omega, the five Greater Doppelgängers in the form of every Pleiades member except Narberal Gamma were present when fighting against the Sorcerer King, Ainz Ooal Gown.
Currently, the musicians are estimated to be at least over five members strong. They also appear to be one of the Greater Doppelgängers like Pandora's Actor. As doppelgängers, they should have the racial feature of taking on the appearance of different people and using their abilities in the process.
After transforming into almost every member of the Pleiades, they are capable of demonstrating similar powers and teamwork tactics to the original. The group's strength is further boosted when Aureole Omega buffed them. For instance, one of the Doppel-CZ2128 Delta is able to stop Ainz from casting his spell.
