Monty Monogram

 is Francis Monogram and Mrs. Monogram's son and has been working in O.W.C.A. since "Minor Monogram". Vanessa Doofenshmirtz seem to become interested in him after she broke up with Johnny, and it is possible that he is slightly interested in her too because he winks at her before leaving.They have coffee together in Sipping with the Enemy, so they might have an actual relationship together.

In "Minor Monogram" he has recently graduated from the "High School Without a Cool Acronym" and he really wants to fight evil following his dad's footsteps. When Major Monogram sees what his son can really do, he expresses his approval. He fights with a combined style of acrobatics and brute force. His father has given him acrobatics lessons since birth, and he really incorporates that into his fighting style, such as flying on a trapeze while kicking someone in the face.

Major Monogram
He is his father and likes him and wants to help him sometime in the future.

Perry the Platypus
Though they have never had any screen time with each other, it is likely Perry likes him and vice versa.
