Fred



Fred is one of Candace Flynn's future children, which appears in "Phineas and Ferb Quantum Boogaloo." He is the son with blue eyes and brown hair. He and his brother Xavier are generally quite inactive, and constantly to make note of how they are sitting in front of the digital tree in his backyard of the family, much to the chagrin of her sister Amanda. Fred keeps talking about being next to something (Fred: "I'm sitting next to him," I'm sitting next to her, "I like the guy standing next to him").

His life takes a turning point, however, when by chance receives a visit from the age younger versions of his uncles, Phineas and Ferb. After the previous visit, Xavier and Fred build bumper cars that can move in five dimensions, but Amanda still answer questions about their activities with "Nothing", which bothers too no end.

In a recurring joke from previous episodes, Candace mentioned that in future she will marry Jeremy and have two kids Xavier and Amanda. Fred inclusion is almost certainly intended as a play on this theme, which implies that, alternatively, Candace finally changed plans or just have more children than she had expected. This problem is further complicated by the assumption that Jeremy is married to Candace, on the basis of genetics in the real world, a redhead and a blonde having a brunette child would be very unlikely. The gene for brown hair may have skipped a generation or so, but there has been no evidence of that situation so far, all known Flynns red hair or natural hair color is unknown, and all known Johnsons are blond. It's also possible that Fred is a step-brother to Xavier, to parallel, Phineas and Ferb. If this is true, Candace would have had to have split up with Jeremy or married someone else before him. There is also a possibility that Fred is adopted.

He and Xavier are about the same age, which means it can be twins if not brothers.

Fred and Xavier are bright and creative, and build impossible things as Phineas and Ferb, even though he had the younger version of his uncles to take them.
