Forum:Villains in Phineas and Ferb

Over the past year, we have had several characters marked as being a villain, followed almost immediately by that category being removed. It's happened often enough by several different people that I think it's time to make a decision as to which characters are villains in the series.

Some are pretty easy. Heinz Doofenshmirtz is a villain, as are all the other members of LOVEMUFFIN and those with an OWCA Agent assigned to them like the Regurgitator.

But what about Vanessa? She's admitted to being "a little evil" in "Summer Belongs to You!" and took her doll back from a girl, but does that make her a villain?
