|~ The Biker trying to flirt with Vanessa, the very same words that sealed his fate.|
The Biker is a minor antagonist in the Phineas and Ferb episode "Vanessassary Roughness". He is an unnamed biker who likes to flirt with young girls.
As the evil scientist Heinz Doofenshmirtz is riding on his scooter with his daughter Vanessa to the Superduper Mega Superstore, Vanessa comments to her father that she's old enough to have a car on her own. Around the same time, the Biker comes by on his motorcycle and overhears Vanessa. Taking a supposed interest towards Vanessa, the Biker asks her if she likes to take a ride in a 'real bike', implying that he intends to take her away from Doofenshmirtz and flirt with her into a romantic relationship for his own purposes. However, an outraged Doofenshmirtz deduces this and points out that Vanessa is too young for the Biker.
In an act of karma, Doofenshmirtz uses his Away-Inator on his helmet to send the Biker to another dimension; even Vanessa herself is indifferent over the Biker's fate, implying that she too was disgusted by his attempt to flirt with her. In the other dimension, the Biker is shocked to be finding himself at the crib of a giant baby alien, who playfully (yet painfully) smashes him and his motorcycle with a rubber mallet. It is unknown what happened to the Biker afterwards.
- The Biker is considered to be one of the few disliked characters in the show given to his desire to hit on underage girls; even Doofenshmirtz finds him despicable for this reason.
