Dyzeps
From Tardis Wiki, the free Doctor Who reference
Dyzeps was a parasite hired by Agnostina to infest Andrew Jacob Skrelli and cause a scandal. Instead, Dyzeps is surprised by how Skrelli resists him and falls in love, attempting to woo Skrelli. Eventually, Abbess Anin comes upon the pair and binds them together in symbiosis, though with Skrelli in complete control. (PROSE: The Sisters Of The Little Moments)
