You're very welcome! : )

Oh my goodness, what an interesting observation. It does raise one particular question: Does Perry -- excuse the poor analogy -- "join the dark side"?

The above series of promotions features Alternate Phineas, Ferb, Candace, Doofenshmirtz, and *our* Perry. We are aware that Alt. Doof is a de facto tyrant, hence, an evil persona. His inclusion in the group seems to imply that the alternate characters -- and even Perry -- are, in fact, opposed to "our side". Now, whomever the resistance may be is ambiguous. In Doofenshmirtz's case, it is evidently Phineas, Ferb, Candace, etc. In regards to the other alternates, though, the resistance may be Alt. Doof himself. It just seems odd that Perry is juxtaposed with the alternates both here *and* on the DVD cover.

Or, I'm simply overanalyzing this. May just be the film's tagline and a means of promotion. Ha.
