Serphyl is an Eyrie owned by BaffleBlend. She's an experienced alchemist with a theatrical air to her demeanor, and prides herself in her study of morphing potions. She was branded with body markings during the Obelisk War in Neopia, signifying a curse—in her case, her two dormant past lives, which included derek964, were awakened from being sealed. Azalea Zefras is her older sister, and she's highly protective of her.
She's MtF. Even though sex changes among neopets are often forced by circumstance, such as via the random-effect "lab ray", her becoming female was entirely voluntary and permanent, via knowingly taking the "Strange Potion" item. Her personality has remained largely unchanged by this, save for her being more confident and comfortable and (slightly) less of a grouch than she was. She will not be drawn as a male except in images explicitly depicting the past.

She exists on the Neopets website: http://www.neopets.com/petlookup.phtml?pet=Serphyl
