Chirag Gupta is a supporting character in the Diary of a Wimpy Kid series. He is an Indian friend of Greg Heffley. He has only appeared as a supporting character in the online and book version, but his role is extended in some of the films. In the first film, he is serving as an occasional addition to Greg's circle of friends, and he also warns him and Rowley about the Cheese Touch.
Chirag appears in All Star Smashers as a Support Spirit, as an Ace class, where you must fight Greg at Soak Central to obtain him. When fighting Greg, he will become invisible, and his punches will have increased power.
