The Nega-Flynn-Fletchers

These are the Negative versions of Phineas and Ferb. They will appear in Season 3 of New Super Flynn-Fletcher Bros!

Nega-Phin
He's the Doofenshmirtz of the Nega-Flynn-Fletchers. He thinks up evil Inators to take over the Nega-Tri-State Area. Well, he used to. After Isabelle's takeover, he went into hiding with Nega-Ferb. He was never seen after that; not even by the other Nega-Humans.
