Taciturn, being nearly completely nonverbal and seemingly emotionless, he has a dry sense of humour and a particular fondness for sugar. Has an unusual talent in extremely destructive magic, and a more understandable knowledge of defensive magic. Takes after his mother more than the rest of his siblings, in both appearance and personality.
Bears a close resemblance to his uncle Arlon, something that had not gone unnoticed by Glados. Both of them, too, have suffered severe trauma that had hamperedtheir abilities and divinity and left them bitter and crippled; Arlon physically, Phillip spiritually.
