Dennis Raven

Dennis Norman Raven is a major villain in Totally Spies Not and its second series Totally Spies: Brotherhood. He is the first-born son of Augustus Raven and Miranda Weatherly, the older brother of Dustin Raven, the eldest grandson of Terence Raven, Emily Raven, Warren Weatherly, and Katrina Weatherly (nee Walls), the eldest nephew of Jonah Weatherly, the adoptive eldest nephew of Fauntleroy Donaldson, the great-grandson of Clyde Weatherly, Nancy Weatherly (nee Chalk), Thomas Walls, and Martha Walls, and also the great-nephew of Kyle Weatherly, Samantha Weatherly, Gary Weatherly, Barbara Walls, and Katrina's four older brothers. He was voiced by Brittney Karbowski as a child, and Breckin Meyer as a teenager.

Personality
Dennis is an aggressive and also has a nasty mouth with a murderous nature. During his first debut in "Jonah's Nephew", he pretends to be a sweet, nice and friendly boy, but he is actually a ruthless, sadistic, intelligent, and cold-blooded murderer (just like his maternal uncle Jonah Weatherly). Fighting seems to be natural for him, as he often casually talks with his enemies and smiles wickedly at them before killing them in cold blood without showing any remorse. Dennis harbors a bitter hatred for his Weatherly bloodline, despite the fact that his mother's real maiden name was Miranda Weatherly, prior her marriage with his father Augustus Raven. He did however greatly respect his paternal grandmother Emily Raven (his mother's mother-in-law), who died in a brutal car accident when Dennis was eight years old.

Appearance
Dennis appears as an innocent young boy with short dark hair and mint green eyes in order to conceal his true, wicked nature. Despite his murderous nature, however, he has no interest in killing innocent people.

Quotes

 * My maternal grandmother Katrina Weatherly put me in charge of Dustin while she's out of town today, so wherever I go, he goes!
 * Yeah, well, he didn't even say anything to me at all. Uncle Jonah knows where his younger cousin Ingrid Weatherly's hiding.
 * Nobody even told me why my paternal grandmother Emily Raven had to die like that.
 * Nobody even told me my maternal great-grandfather, my mother's paternal grandfather, my father's grandfather-in-law, my maternal grandmother's father-in-law Clyde Weatherly had to die like that.
 * Yeah, well, she didn't even say anything to me at all. My maternal grandmother Katrina Weatherly knows where her sister-in-law, my maternal great-aunt Samantha Weatherly's hiding.
 * (to his maternal grandmother Katrina Weatherly, while referring to his late maternal great-uncle Kyle Weatherly) Kyle Weatherly was your brother-in-law and my maternal great-uncle? Funny how you failed to mention that before.
 * (when confronted by Inga Bittersweet's goons) I don't have time for this! Get out my way!
 * Then that means he is no longer my maternal grandfather.

Augustus Raven
Augustus is Dennis Raven's father. It is unknown what Dennis thought of Augustus before the events of Totally Spies: The Return of Augustus Raven, but Augustus's werewolf-like alter-ego tried to extract Dennis's werewolf blood forcefully from him at the end of Totally Spies: The Return of Augustus Raven. When Dennis awoke, he told Augustus that he would perish and the two fought, with Dennis winning. Since then, Dennis has desired to destroy the Weatherly bloodline once and for all, and especially the werewolf blood and his father who revels in its power. Augustus and Dennis have not come into direct contact since, but Augustus opposed the anti-communist war that Dennis started with the Weatherly Financial Empire by taking over and militarizing Raven Corporation. This apparently was in accordance with Dennis's evil plans, however, as a war with his father was needed to awaken Azrael.

In Totally Spies: Savage Retribution, Augustus seems to have lost interest in Dennis's werewolf blood, mainly due to him being focused on fighting his cousin-in-law Irene Weatherly (his father-in-law's youngest niece), but Dennis still wants to kill his father as seen in the epilogue.

Katrina Weatherly (nee Walls)
Katrina is Dennis's maternal grandmother on his mother's side. Katrina took him and raised him during the events leading up to Totally Spies: The Grandson of Katrina Weatherly after his paternal grandmother Emily Raven was brutally killed in a car accident. Dennis was trained by Katrina in the Weatherly style fighting karate in order to prepare him to fight the Evil Entity, eventually in nearly three years mastering the Weatherly style and implementing it with what he learnt from his late paternal grandmother. Dennis trusted Katrina with his life, and looked up to her as a mother figure, but after Katrina betrayed him after he had killed the Evil Entity, Dennis started to dislike Katrina and his family lineage, causing Dennis to abandoned and reject his Weatherly heritage, including his maternal grandmother's fighting style. In Totally Spies: The Return of Augustus Raven, a vision of his late paternal grandparents, Terence and Emily Raven, made Dennis decide not to kill his maternal grandmother, sparing her life in the process after having defeated both her and her son-in-law Augustus. However, Dennis is completely aware that his mother's real maiden name was Miranda Weatherly, prior her marriage with his father.

Nancy Weatherly (nee Chalk)
Nancy is Dennis's deceased maternal great-grandmother on his maternal grandfather's side. The to met in Totally Spies: The Resurrection of Nancy Weatherly, and Dennis kill her in order to free her from the spirit possessing her and to take control of the Weatherly Financial Empire.

Fauntleroy Donaldson
Fauntleroy is Dennis's adoptive maternal uncle, who protected him during his coma in Totally Spies: Savage Retribution from an attack from Fauntleroy's adoptive older brother, Dennis's maternal uncle Jonah Weatherly and the Violet Ribbon Army.

Warren Weatherly
Warren is Dennis's deceased maternal grandfather on his mother's side and the original source of his werewolf blood. It is unknown, however, whether he knows him or not.

Trivia

 * Along with his maternal grandmother Katrina Weatherly (nee Walls), Dennis is likely one of the two villains who openly refuses to be Helga Von Guggen's allies. This makes him a polar opposite to his maternal grandfather's nephew-in-law Peter Oliver, who only joined Helga Von Guggen's side reluctantly prior to finding out the truth from his maternal grandmother's rival Rainbow Dash.
 * Aside from his mother and maternal uncles, none of Dennis's aunts and uncles were never seen or mentioned.
