Phoenix idolizes his cousin Jonah and tries to be just like him. Nevertheless, he thinks his rapping is "just talking, really. Bragging in time to a simple repeating beat." He doesn't think Jonah's raps are very creative. He seems to be a fan of classical music. Nellie describes him as "sweet" and "just a kid". Even though he tries to be like Jonah, he is very different from him.
He was kidnapped by the Vespers while at a Jonah Wizard concert, right from the nose of security. He was the last of the seven hostages to be captured, because of his far distance, which was in Tokyo. When the Vespers shot Nellie Gomez in the shoulder, he appeared to be crying.

In Shatterproof, he is the only one of the hostages who escapes after falling off a steep ledge, into a turbulent river and surviving in the jungle.
