W.I.T.C.H. Wiki

Maria Medina is an Interpol agent from the crime psychology department who was assigned to investigate the Brown family's disappearance along with Joel McTiennan.



Maria and Joel

Agent Maria Medina, along with Agent Joel McTiennan and Tom Lair, investigated Elyon Brown's disappearance. They looked around the Brown's home for clues to the family's disappearance alongside Tom Lair and McTiennan found a photo of Elyon and the W.I.T.C.H. girls taken at the Halloween party and recognized one of the girls as Irma Lair, Tom Lair's daughter.[1]

This led to Will, Taranee, Cornelia, and Hay Lin visiting the Lair house, seeming under the pretense of joining the family for dinner, but in reality, it was so that both agents can interview all five girls about Elyon.[1]

Medina thought the W.I.T.C.H. girls were hiding something that would be helpful to their case, so as a result Medina and McTiennan tried to keep a close eye on the girls. They held a stakeout at Cornelia's home. Will, trying to smuggle Cornelia away, brought a disguised Vathek and an Astral Drop of Herbert Olsen, Matt Olsen's grandfather, who barely knew how to drive. Using this as an advantage, the Astral Drop asked both agents questions about driving which acted as a diversion while Will and Cornelia snuck into the van where Vathek was hiding.[1]

As Matt's "grandfather" drove away, the van's back doors flew open, revealing Cornelia and Vathek for a moment. Medina, seeing this, ordered McTiennan to follow them. Their car wouldn't start, and McTiennan briskly went to have a look at the engine. He found plants twisted around the engine, thanks to Cornelia, who helped a small plant directly under the car to grow.[1]

Medina and McTiennan returned to the Brown Family's basement, looking at a wall which does not appear on the house's blueprints (which was put up by during a magical fight previously). McTiennan tried to break down the additional wall, initially with a large hammer, then suggested using dynamite. Agent Medina said he should stop so that the house was not destroyed.[2]

Later at Irma's house, Maria Medina tried to talk to her but was stunned to see two Irmas, one being the real Irma, the other being the Changeling, which took the form of the Guardian of water. Medina dismissed the confusing sight, saying she might be working too hard.[3]

Later, they talked with Ralph Raphael Sylla, also on the police force, about the strange incidents that all five W.I.T.C.H. girls were all seen around, alongside Raphael Sylla, and started investigating the girls.[4] They were also seen discussing the same issue with Nora Frieder, also on the police force and who asked Medina and McTiennan to spy Sylla and his investigation.[5]

Medina, McTiennan and Scylla all worked together to stop Mr. Riddle. In the confrontation, guns were drawn and pointed at different parties in a standoff. This was resolved when The Oracle pulled everyone there to Kandrakar, where he used a memory spell on everyone there to remove their memories of the W.I.T.C.H. girls.[5]

TV series

In the TV series, Maria Medina and Joel McTiennan were hired after Alchemy raised questions about Elyon's absence and were fooled by Miranda and Sandpit into thinking that the Guardians were responsible for Elyon's disappearance. The two police officers nearly arrested W.I.T.C.H., but Elyon and her parents arrived with Caleb and Blunk (glamoured as a puppy) at airport to end Maria and Joel's suspicions staging that the family was on a trip.[6]


  • Because of their different builds, McTiennan and Medina are affectionately referred to as "Big Guy and Small Fry" by their colleagues.[1]
