~ Dr. Killbot introducing himself to the public during L.O.V.M.U.F.F.I.N.'s press conference.

Dr. Killbot, also known as Señor Killbot, is a supporting antagonist in the Phineas and Ferb special, Phineas and Ferb Saves Summer. He is a robot with a human brain who serves as one of the members of L.O.V.E.M.U.F.F.I.N. and can only speak improper Spanish.

He was voiced by Mike Bell.


Upon hearing that Heinz Doofenshmirtz has succeeded in moving the Earth away from the Sun to early autumn with his latest -inator, Killbot and the other villains are very impressed by this. At that moment, Aloyse von Roddenstein decides to lead L.O.V.E.M.U.F.F.I.N. to take over the world, so Killbot helped out in capturing almost all of O.W.C.A.'s agents (except for Perry the Platypus). The villains then head over to Danville City Hall, where Rodney introduces Killbot to the people in case any of the world's extorters speak Spanish, since he doesn't want to leave anyone out.

Killbot was present when Rodney contacted the world leaders about the progress of their plan, and when the world leaders informed that the pretzels demand is the only one that hasn't been met, Killbot watches as Rodney sets his -inizor (which is just ten times the size and strength of Doof's -inator) to send the Earth to perpetual winter, delighted to see that the world is now under L.O.V.E.M.U.F.F.I.N.'s grasp.

During the climax, Killbot is seen trapping the arriving Monty Monogram, Carl Karl, and Perry (thanks to the help from Dr. Diminutive and another unnamed evil scientist), but they are interrupted by Monty's father Major Monogram, who arranges for a street rat to free all the captured agents. This resulted another fight between the agents and villains, which happens to be the same one earlier in a ballroom during the beginning of the special. When this was pointed out by Diminutive himself, Killbot and the other villains decided to flee away from the scene for good.



  • Dr. Killbot one of the three members of L.O.V.E.M.U.F.F.I.N. to be a robot (the others are Norm and Chloe).
  • Dr. Killbot only speaks in Spanish in the English dub. Yet he spoke in a broken English in the Spanish dub. He's also referred to as Mr. Killbot in the Spanish dub.
  • Dr. Killbot is referred to as Señor which means either Mister or Doctor in Spanish.
