"Doofus Khan's secret weapon", called as such by Princess Isabella, is a giant robot dragon created by Doofus Khan as a last resort method. He activated this after the princess escaped thanks to Phineas, Ferb, Buford and Baljeet.

The robot, while it was attacking the city, engaged in combat with a Giant Terracotan Warrior, and was about to win before Master Perry intervened, revealing It's weak spot so that the kids could take it out, the robot collapsing shortly afterwards.
