Thief Phoenix is based on the Phoenix, as evident by its name. In mythology, the phoenix was a sacred firebird made of a large variety of colours and such. The phoenix would usually live for about a 500 life-year span, while at the end of it, creating a nest of twigs. The phoenix and its nest would burn into nothing more than fiery ashes; where in turn, a new phoenix or phoenix egg would appear. This new phoenix would then be destined to live for as long as its ancestor; thus being reborn. As is, the whole purpose of the phoenix: to be reborn and in a way, live forever; immortality.
The phoenix appears in many different cultures, mythology, and such. The aforementioned Bey has of course, a phoenix motif. This can be seen with its Stone Face, as well as its Chrome Wheel.
Its Japanese name, "Phoenic", can quite possibly be a portmanteau involving two other words. The first, can be of "phoenix" and "Phoenicia". This is because the phoenix also has mythological roots in the real-world place of Phoenicia. The second possibility, is between "phoenix" and "fushichō". Fushichō was the Japanese name for the phoenix and literally meant, "immortal bird". Although, another reason for "phoenic" can be simply because, the name Phoenix was previously used, so it was simply change one letter to avoid confusion over the former (however Hasbro decided to revert it to "Phoenix".
Thief obviously refers to a person committing thievery; the stealing of another person's belongings without their consent. The word "thief" being used in this Beyblade's name may be a reference to how in the anime, Phoenix "steals" Samurai Ifrit's special move.
