Dr. Ahmed Kareem was once a colleague of Dr. Benton Quest.
Kareem wore a white suit, with a yellow shirt and black tie, along with a red fez. He had black hair with whiting temples, brown eyes, and a small, black mustache.
Dr. Kareem summoned Dr. Quest, family, and Race Bannon to Egypt, telling them to come to see his latest find: the remnants of a lost city. However, Kareem had other plans for them. Unknown to him, the mummy of Anubis had broken free from its tomb and was coming after him for the dastardly deed he was going to commit.
Kareem's plans were to lock Race and Dr. Quest down in a tomb in the remnants of the lost city with some adders and one of Anubis' treasures so they'll be framed for the crime of stealing one of Anubis' treasures, and will be in big trouble, dead or alive. Then he would sneak back into the tomb and steal the treasures. This succeeded until Jonny and Hadji stopped the adders and saved Dr. Quest and Race. In a rage, Kareem started to shoot at them in an attempt to kill, but Anubis' mummy showed up and punished Kareem for his dastardly deed. When Anubis' mummy caused a cave-in, both were crushed by rocks and killed.
