Vanessa is the offspring of Dr. Heinz Doofenshmirtz and his ex-wife Charlene. She is 16 and is bent on proving to her mother that her father is evil. Although she hangs out with the wrong crowd, it seems this attitude is only skin deep. In certain episodes you can tell she really cares for her parents. Also, although not so subtle, every once in a while there is a hint towards her and Ferb Fletcher getting together. She is also one of the very few people who knows about Perry's secret life as an agent. She is pretty good friends with Candace Flynn and enjoys parties at scrapyards.
