Detective Lieutenant Chin Ho Kelly was a former highly decorated HPD cop before being wrongly accused of corruption which resulted in his career and reputation being tarnished.
For a short time, after Governor Pat Jameson's murder and Hawaii Five-0 being disbanded, Chin temporarily joined the Honolulu Police Department once again but after Steve was cleared, Hawaii Five-0 was reopened and Chin officially rejoined the team.
Born and raised in Hawaii, Chin lived a relatively normal life and during his time in high school, befriended teenage Steve McGarrett.
At some point, in his later adult years, Chin joined the Honolulu Police Department but his career was ultimately left in tatters as he took the fall for his uncle, Keako who had stolen money as Keako's wife and Kono and Chin's aunt, Mele was gravely ill and needed a kidney.
Not wanting his uncle to be shamed, Chin took the fall with many of his former officers regarding Chin as a thief.
After resigning from the HPD, Chin became a security guard with the fallout prompting him to leave his fiancée, Dr. Malia Waincroft for her protection.
In the Pilot (episode), Chin was reunited with Steve and instantly agreed to join the unnamed Task Force, Chin's technological skills and knowledge of Hawaii in general giving the team a huge advantage.
In Season Two, Chin proposed to his former fiancee, Dr. Malia Waincroft, and the two were later married in a beach ceremony, in the company of their friends and family.
He and Detective Danny Williams join forces with NCIS Special Agent G. Callen and Special Agent Sam Hanna to stop a smallpox outbreak from happening during Pa Make Loa (episode) with both teams heading to Los Angeles to stop a worldwide pandemic from occurring in the concluding episode, Touch of Death (episode).
In the finale, he was forced to choose between rescuing his wife or cousin.
In the premier, Malia died from her wounds, leaving Chin devastated although he later avenges her death while the team is later seen at her funeral (3.02). In the finale, he called Leilani out for a date.
In an alternate reality seen in Ina Paha (episode), as a result of the Hawaii Five-0 Task Force not being created, the Chin of that reality is presumably still highly respected and admired as a Detective.
As such, he has been promoted to Captain and also maintains a high position in the Honolulu Police Department.
Despite the accusations against him, Chin is an honest cop through and through although Chin has expressed some hurt at the fact that many of his former HPD colleagues don't trust him at times.
