The 2nd Dimension Charlene Doofenshmirtz is 2nd Dimension Doofenshmirtz's wife, and the main antagonists in Phineas and Ferb episode Tales From the Resistance: Back to the 2nd Dimension. She is an alternate reality version of Charlene Doofenshmirtz (the ex-wife of Heinz Doofenshmirtz), but unlike her original counterpart (who is civil and unaware that Doof is an evil scientist), she is shown to be very evil and intelligent, sharing much of 2nd Doofenshmirtz's personality in general.
