Xavier is Candace's (and possibly Jeremy's) future son who appears in the episode "Phineas and Ferb's Quantum Boogaloo". He appears to act like his uncles, but reversed, as he loves nothing more than to sit by the virtual tree. His catchphrases are "I'm sitting under this digital tree". His brother is Fred. He appears in The Xavier and Fred Show and its movie.
