Spiteful, Impatient, and with a constant drive to "get stronger", Millie had no qualms with being the test monkey for Kate's experimental hormone enhancement.
The chemical cocktail, known as "Sekhmet" is injected into Millie's veins at a steady rate, but can be increased in dosage as she so chooses, though she has been warned the "dangers of overdose" and to not strain her systems too hard when on the drug, Millie seems to either have not been listening, or simply not care.
Her birthday is July 6th
Her favorite food is rare steaks
She's not gonna stop and you know it so it's not worth wasting breath to tell her she should.
