Mesmerella is the debut of the newest power player in the Metrobay Universe. Enchantress is ordered by Ms. Metrobay and Alpha Woman to seek professional psychiatric help in dealing with her persistent criminal urges and visits professional hypnotherapist Ella Mesmer with Spellweaver tagging along. Instead of helping her, however, Ella hypnotizes both heroines and orders them to give her their magical powers, transforming her into the titular Mesmerella.
Using her new powers, Mesmerella stages an erotic hypnosis show for R.O.P.E. with the guest of honor, Omega Woman, being tricked on stage, entranced, and paraded about for their enjoyment.
