Tom Felton portrays Julian Albert Desmond in season three of The Flash, while Tobin Bell provides Doctor Alchemy's voice when masked.[5] The character is a forensic scientist and Barry Allen's rival in the CCPD while Doctor Alchemy wears an outfit similar to the classic plague doctor's costume with a face-concealing, beaked mask. An acolyte of Savitar, he can manifest from mirrors and possesses the Brahmastra (also known as the Philosopher's Stone), an ancient Hindu weapon with the ability to restore the powers of metahumans who existed in the alternate "Flashpoint" timeline. Alchemy displays knowledge of the "Flashpoint" timeline even after a variation of the original one is in place, with Julian's presence being one of the changes made to the timeline.
