Rajan has appeared only in Sly 2: Band of Thieves.
Rajan was in possession of the Clockwerk Wings, flaunting them publicly during his party at his newly bought palace in India. Thanks to an operation involving Sly distracting the partygoers, including Carmelita Fox, Neyla and The Contessa, Murray managed to steal the Clockwerk Wings.
Because of this incident, he went into hiding deep in the jungles of India. He was hiding in an old abandoned temple, using one half of the Clockwerk Heart to run his spice production plant, while the other half was used on his weapon. Bentley used Rajan's love of Indian watermelons to put him to sleep, so he could steal the blueprints for his operation. This spooked Rajan into hiding.
To get Rajan out of hiding, the Cooper gang decided to break the dam behind the temple to flood him out. This caused Rajan to get angry and demand the Cooper gang to come out and face him. Neyla crossed the Cooper gang, knocked Sly unconscious and watches as Murray and Rajan did battle. In the end, Rajan was defeated, and then arrested by The Contessa (Sly, Murray and Carmelita were also arrested). During the game's ending credits, it is revealed that Rajan became the owner of a rug dealership franchise in North America after he served his time.
